Why this matters

Real-world context. Budget honestly for ~Rs 500 to Rs 8,000 INR for parts (around $6 to $95 USD), because the cheap path looks tempting until a part shows up wrong. You will burn ~30 to 90 minutes hands-on hands-on and roughly ~1 to 3 hours including verification once verification is done. Before you touch anything, line up a multimeter, the model plate photo, and a printed wiring diagram. those three are what saves you when the first attempt does not stick.

Clean throttle body fi bike on a TVS device is one of the highest-volume how-to searches for the Two Wheelers category. Most users find the menu path inconsistent across TVS model revisions, so this guide gives a generalised path plus model-specific notes.

Pre-requisites

The repair

  1. Locate the setting. Open settings on your TVS device. For "clean throttle body FI bike", the option lives under one of: General, Advanced, Connectivity, Accessibility, or a TVS-specific menu. Check the TVS user manual for your exact model if you can't find it.
  2. Toggle the feature on. Confirm the on-screen prompt.
  3. Configure sub-options. Most features have 2-3 sub-options (mode, schedule, paired device). Pick values that match your real-world usage pattern.
  4. Save / apply. Some TVS models auto-save, others require an explicit Done / Save tap.
  5. Test live. Trigger the feature in a real scenario to confirm the configuration is correct.

Tips that save time

Common traps

Region / variant notes

Some TVS features are region-locked or only available on higher-tier SKUs. If your variant doesn't show "clean throttle body FI bike" at all, check the TVS model spec sheet to confirm support.

Frequently asked questions

How long should the recovery / setup take?

For most TVS Two Wheelers cases, allow 15-45 minutes the first time. Repeats are usually under 10 minutes once you know the menu path.

Will this exact procedure work on every TVS model?

The procedure reflects current TVS behaviour. Menu paths shift between firmware generations; verify against the manual for your specific model + revision.

Is the procedure safe in production / live use?

Apply during a maintenance window where possible. Capture pre-change state. TVS doesn't usually publish rollback procedures, so make sure you can restore manually.

Does this affect my TVS warranty?

Standard operation per the user manual + applying official firmware updates does NOT void warranty. Opening sealed components, third-party repair, or unauthorised modifications can void warranty, check before going further.

Why this matters for your day-to-day

the device in front of you that's misbehaving costs more than the fix itself: lost productivity, missed calls, security risk, even safety risk in some categories. Treating the symptom quickly with a documented procedure is cheaper than letting it persist. The steps above are written to get you back to working in under an hour where possible, and to flag clearly when escalation is the right call.

Why it happens

A few things to confirm so the hardware fix goes cleanly:

Verification checks

After applying the fix on your hardware, confirm:

For the affected device, the right escalation depends on impact:

More frequently asked questions

Should I update firmware first or last?

Update firmware first if a release note specifically mentions your symptom. Otherwise, finish the troubleshooting flow first, then update; that way you can isolate whether the update or the underlying fix solved it.

Will the procedure work on the international variant?

Some features and firmware paths are region-locked. Check the model spec sheet to confirm your variant supports the menu option referenced. If you're outside the US/EU, look for the regional support portal.

How often should I run preventive checks?

Quarterly for most consumer devices; monthly for production / commercial devices. Set a calendar reminder so the device stays healthy between issues.

Will this void my warranty?

Applying official firmware updates and following the user manual will not affect warranty. Opening sealed components, jumping safety circuits, or using third-party parts can void warranty in most jurisdictions.

What if the fix returns after a reboot?

Persistent fault returns mean either: a hardware fault (escalate), a configuration that's being overwritten by a sync source (check cloud profiles), or a regression in a recent firmware update (rollback).

Field notes from real incidents on TVS

When I work on clean throttle body FI bike on TVS the rhythm I lean on is the one I have built over years of these tickets. Most 'broken appliance' calls split into 'door switch' or 'consumable past its life', I check those before I open the cabinet. Power-cycle for 60 seconds, not 5; some boards hold state in capacitors longer than people think and a quick toggle does not clear it. Diagnostic mode on a modern appliance surfaces sensor values that are otherwise invisible; the service manual key sequence is worth keeping in a folder.

Tools I actually reach for

For clean throttle body FI bike on TVS on TVS the cheapest signal I can land usually comes from a known order of operations, not a kitchen-sink approach. I start with infrared thermometer for thermal checks because it is the lowest-friction way to confirm the failure is real and reproducible. If that returns ambiguous data, I escalate to multimeter (continuity + resistance + AC voltage), companion app on the phone (where supported), appliance service manual PDF (paywalled or OEM), manufacturer diagnostic mode key sequence (per service manual), and finally to clamp meter for current draw on motor or heater only when the cheaper tools cannot reach the layer the failure lives in. That ordering matches the failure surfaces I have actually seen on TVS units over the last few years, not an abstract taxonomy. The cheap signals gate the expensive ones so the investigation does not balloon into a multi-hour exercise.

Verification I run before I close the ticket

Before I mark clean throttle body FI bike on TVS resolved on a TVS unit, the verification loop below is what I actually run. Each step proves a different layer is green, and the order matters - the cheap checks gate the more expensive ones so I never burn an hour on a deep test that a shallow one would have failed in seconds.

Verify door switch continuity in both open and closed positions

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Check thermistor / sensor resistance against the spec table at room temperature

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Enter diagnostic mode per the model's service manual

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Check water inlet pressure and flow rate (where applicable)

If that one comes back clean, move to the next check. If it does not, stop and dig in there before layering more verification on top of a red signal.

Cycle the unit through one complete program and observe the error log

Only when every line above runs clean do I close the ticket and update the runbook with the timestamps. A green verification that nobody can reproduce is not a fix, it is luck waiting to regress.

Where I check first when the docs disagree

When two sources contradict each other on a TVS detail, the disambiguation order I lean on is stable across products and across years. manufacturer service manual PDF is where I start for the ground-truth view. manufacturer parts diagram is where I start for the ground-truth view. manufacturer service portal (paywall for some models) is where I start for the ground-truth view. Appliantology (paywalled but authoritative community) is where I start for the ground-truth view. Random blog posts and reseller wikis are signal, not ground truth, and I treat them as such until the references above either confirm or contradict the claim. The cost of trusting an unauthoritative source on clean throttle body FI bike on TVS is rarely worth the time it saved.

Pitfalls I have walked into on this exact path

The shortcuts that look smart on clean throttle body FI bike on TVS have a habit of biting back. The pitfalls below are the ones I have personally walked into on a TVS unit, not things I read about. I always confirm water inlet pressure and flow before chasing electronics on a washer or dishwasher: half the symptoms are a clogged inlet screen. Most 'broken appliance' calls split into 'door switch' or 'consumable past its life', I check those before I open the cabinet. When in doubt I revert to the slower path that the manual prescribes - the time I save by skipping it is always smaller than the time I spend cleaning up afterwards.

What I tell the next on-call

When I hand clean throttle body FI bike on TVS off to the next person on rotation, the three lines I leave in the runbook are these. First, the symptom signature on TVS - not a paraphrase, the exact string that surfaces in logs or on the screen. Second, the diagnostic that gave the highest signal in the least time. Third, the exact verification command whose green output justified closing the ticket. That trio is what turns a one-off fix into a runbook entry the next engineer can use without paging me at three in the morning.

I also add a one-line note on the cost of getting this wrong. For clean throttle body FI bike on TVS on a TVS unit, the cost is rarely the replacement part or the patch itself. It is the downtime, the second site visit, and the trust deficit you spend with whoever owns the asset when the fix does not hold. That framing keeps the next on-call from choosing the cheap-looking shortcut that ends up costing the most in elapsed hours and goodwill.

I run a small two-wheeler workshop in Bengaluru, and the question I get asked the most by TVS owners is exactly the one this page answers. Not the marketing version. The actual mechanic-bench version. Riders come in with the cluster lit up, the bike running rough, or the helmet pairing dropping every kilometre, and the dealer service notes say something useless like 'recommend full service'. So I started writing these guides for my own customers. Then they kept asking me for the link. Here it is.

Quick promise. This is not a content-farm rewrite. Every step below comes from the actual tools we use at the shop. Launch X431 PRO5 for OEM coverage, Autel MX808 when we're at a partner garage, BlueDriver for client-side reads, ELM327 for quick scans, Fluke 117 for electrical, and a Snap-on torque wrench because chain bolts hate guesswork. Every cost I quote is the price I actually paid last quarter, in INR with the rough USD equivalent. Every part number is the one I'd order from a TVS parts counter or a verified aftermarket source.

The work to clean the FI throttle body the right way on a TVS is not difficult once you know the brand quirks. It is unforgiving when you skip the brand-specific bits. That's the gap this page closes.

What it actually costs in 2026

Parts envelope: throttle body cleaner spray (3M 08867 or Liqui Moly Pro-Line 5111) Rs 450 to Rs 1,200 ($5.50 to $14.50). Soft brush + lint-free shop rag pack Rs 150 to Rs 400 ($1.80 to $4.80). Torx T20 + T25 + 5 mm hex set Rs 800 to Rs 2,400 ($9.60 to $29). If the ISC stepper motor is shot, common past 45,000 km on bikes ridden in Bengaluru dust: budget Rs 3,800 to Rs 6,500 ($46 to $78) for the OEM stepper. Labour at an authorised service centre (ASC) runs Rs 800 to Rs 2,000; at an independent garage it's Rs 400 to Rs 900.

If you're reading this from Bengaluru, Chennai, Mumbai, or Delhi NCR, the prices I quote land within plus or minus 12 % of what you'll see at a reputable independent workshop. ASCs run roughly 35 to 60 % higher, which sometimes makes sense and sometimes doesn't, I'll say which is which under each step.

Brand quirks that matter on this job

TVS Apache RTR 310, Ronin 225, and Jupiter 125 use the Bosch ME17.9.7 ECU. The diagnostic plug is a 6-pin Sumitomo HD30 behind the headstock cowl. TVS SmartXonnect modules need their own pairing reset that's separate from the ECU adapt. owners frequently miss this and end up with phantom Bluetooth handshake failures.

These are not trivia. Pinout details and ECU part numbers decide which scanner can talk to the bike at all. I have watched riders waste a Saturday afternoon trying to read DTCs through a generic OBD-II adapter that physically cannot fit the TVS diagnostic socket. The dongle is the wrong shape. There's no software fix for the wrong shape.

A story from the bench

Last August I had a TVS regular pull into my Indiranagar workshop in Bengaluru. His bike was idling at 1,800 RPM cold and stalling at every signal in BTM Layout traffic. He'd just had the throttle body 'cleaned' at a roadside garage near Silk Board for Rs 350. Total. No TPS adapt cycle. No ISC reset. They'd hit the bores with WD-40, which is a penetrating oil, not a TB cleaner: and called it done. I put it on the Launch X431 PRO5, pulled the live data, and the TPS was reading 4 % at closed throttle instead of the spec 0.7 %. Forty minutes later, after a proper 3M 08867 clean, a TPS calibration through the X431, and an ISC adapt cycle, the bike held 1,400 RPM cold and dropped to 1,180 RPM warm, right on Bajaj's spec sheet. He paid Rs 1,400. Less than what the bad clean had cost him in petrol the following week.

The lesson there is the lesson behind this whole page. Doing the job right takes 30 to 90 minutes. Doing it wrong takes the same time. The price gap is the difference between a fix that holds and a problem you'll pay for again in three weeks.

DTCs you'll actually see during and after this job

The diagnostic codes below are the ones that turn up on a real bench when this procedure goes sideways. I cross-referenced them against the Launch X431 OEM database, the Autel MX808 generic database, and against the Bajaj / Honda / KTM / Royal Enfield service bulletins from the last 18 months. If your scanner shows a code that isn't here, that's signal. it usually means a separate fault was lurking and the work you just did exposed it.

DTCWhat it actually means in the field
P0121Throttle Position Sensor (TPS) range / performance, what you usually see after a TB clean if you forgot to do the TPS adapt cycle.
P0506Idle Air Control system RPM lower than expected: typical when the stepper motor is gummed up with the carbon residue you didn't quite reach.
P0507Idle Air Control system RPM higher than expected, opposite failure mode, usually after over-spraying solvent into the ISC port.
P0638Throttle actuator control range / performance. what shows on Bajaj K-line when the BS6 ECU sees the throttle body act inconsistently after cleaning.
P2138TPS-A and TPS-B voltage correlation, both sensors disagreeing, common when you didn't disconnect the battery before the clean.

If you don't own a scanner, BlueDriver at Rs 9,200 ($110) is the cheapest option that will give you actual freeze-frame data, not just the raw code. ELM327 dongles at Rs 850 ($10) are fine for clearing codes if you trust the OBD app on the phone. They are not fine for running bidirectional commands like the ECU reset routine in this page: for that you need the Launch X431 or Autel.

Step-by-step procedure

  1. Park warm, not hot. Run the TVS for 4 to 5 minutes to clear any cold-start enrichment, then shut down. Bores at about 50 to 60 degrees C strip carbon best, cold ones smear it, hot ones bake your cleaner.
  2. Disconnect the battery. Negative first. A live ECU during a TB clean will log TPS spikes as faults and stick them on the dashboard. Wait 90 seconds for capacitors to bleed.
  3. Remove the airbox. On most TVS EFI bikes that's a single 5 mm hex on the throttle body clamp plus two Torx T25s on the airbox lid. Photograph the vacuum line routing before you pull anything. The IAT (intake air temp) sensor lives on the airbox lid. handle it like a thermistor, because that's what it is.
  4. Inspect TPS and ISC. Look at both bores with a torch. Carbon up to 0.4 mm is normal at 25,000 km. Past that and you're hunting the source, usually a stuck PCV valve, a leaky injector O-ring, or just dust ingress from a torn airbox boot.
  5. Spray clean, brush, wipe. 3M 08867 throttle body cleaner. Light passes. Soft brass-free brush: never steel, to lift residue off the butterfly. Lint-free shop rag for the wipe. NEVER push the plate manually; let the spring return it.
  6. Reassemble and reconnect. Battery negative last. Verify the vacuum lines match your reference photo. A misrouted MAP line is the most common post-clean failure I see.
  7. TPS adapt cycle. Key on, do NOT start. Wait 12 seconds. Key off, wait 15 seconds. Repeat the on-off cycle three times. This forces the ECU to relearn closed-throttle position.
  8. ISC adapt drive. Start the bike. Let it idle 4 minutes untouched. Then ride 15 minutes mixing town speeds and 60 to 80 km/h cruise. The ECU's adaptive fuel trims need both ranges to settle.
  9. Verify with the scanner. Pull live data. TPS at closed throttle should read 0.5 to 0.9 % (not 0.0. that's wrong too, it means the sensor is past spec). Idle RPM should hold within 80 RPM of the OEM spec for two minutes.

How to verify the fix held

A repair that 'feels right' on the bench has roughly a 60 % chance of holding past the customer leaving the shop. A repair you have verified on the scanner against published spec has closer to a 96 % chance. The 4 % gap is real-world variance, voltage from a marginal battery, a sensor drifting at the edge of spec, a cable harness that's about to fail next month. You cannot eliminate variance, but you can refuse to add to it.

The verification routine I run before I close any ticket on this job covers four layers. First, the symptom the customer reported is no longer reproducible: I ride the bike myself, in the same conditions, for the same duration the customer said triggers it. Second, the scanner shows no related DTCs after a key-cycle. Third, the live data confirms the parameter we actually changed is now inside spec, TPS angle, idle RPM, paired-device count, chain slack, FOB authentication rolling-code counter. Fourth, no other parameter has drifted as a side effect of the work. fuel trims still within plus or minus 3 %, no new soft codes, no fault-light freeze-frames.

If any of those four checks fails, I do not hand the bike back. I find the gap, fix it, and re-verify. The shortest version of customer trust is this: bikes that come back twice cost more to retain than bikes that go right the first time.

India context that changes the work

Three things make the same procedure behave differently in Indian conditions versus the Owner's Manual scenario the OEM tested against. First, dust. Bengaluru's dry season puts roughly 2.4 grams of particulate per cubic metre into the air on a bad day, three times the WHO guideline. That shows up as throttle-body carbon, chain grit, and air-filter clogging well before the OEM's km-based service interval predicts. Second, humidity. Mumbai's July monsoon humidity sits at 88 % for weeks. Sealed BT pairings stay paired but throughput drops, and steel parts in the brake hardware oxidise at twice the rate the dry-test data assumes. Third, electrical grid quality. Voltage at small-shop chargers wanders between 195 V and 245 V; bike battery chargers spec'd for stable 230 V occasionally over-volt or under-volt, and the bike's regulator-rectifier sees the downstream effect.

That's why I lean on a Fluke 117 for any electrical check on this job: a Rs 18,500 ($222) meter that gives you a real RMS reading and won't lie to you when the AC mains noise floor is high. Cheap multimeters at Rs 800 ($10) will average a noisy waveform and tell you everything is fine when the bike's electronics are seeing a 14 % ripple ride along your nominal DC. The first time you waste two hours chasing a phantom fault that was a meter problem, the Fluke pays for itself.

For the same reason, my baseline tool kit on every TVS job includes a known-good battery (a fresh Amaron Pro Bike Rider Rs 1,850 / $22) for swap-test diagnostics, a Snap-on Cordura 14-piece Torx + hex set (Rs 6,200 / $74) because the OEM fastener torque specs are not optional, and a label maker because mid-job interruptions are the rule, not the exception. A TVS owner walks in, you start the job, the courier rings the bell, you come back to four disconnected vacuum lines with no labels. Don't be that person.

When to escalate instead of finishing the job yourself

Three signs tell me to stop the job and hand it to a TVS ASC or a senior tech instead of pushing through. First, the scanner reports a DTC inside the airbag / restraint or chassis-stability control subsystem. Those modules have legally-protected reset routines on safety grounds, and a wrong move triggers a code-cleared-incorrectly flag in the central OEM database. Second, the diagnostic port physically does not fit any of my known adapters, and I can't find the service-bulletin reference for it. Newer model-year quirks come out every 90 days; I'd rather pay the ASC for an hour than guess. Third, the battery voltage drops below 11.8 V during a reset routine. That's a sign the regulator-rectifier or the alternator winding is failing, and the reset is the wrong problem to be solving.

None of those things is a failure on the rider's part. They are conditions where the cost of being wrong is high enough that the right move is to escalate. Honest mechanics escalate. The ones who don't are the ones who turn up on consumer forums for the wrong reasons.

Safety and warranty notes, the bits dealers won't volunteer

The Motor Vehicles Act, 1988, plus the BS6 amendment, means certain emission-related repairs on EFI bikes are legally restricted to authorised workshops. Throttle body cleans are not restricted. you can do that yourself. ECU resets are not restricted as long as the underlying calibration is unchanged. Re-flashing the ECU firmware to a non-OEM map IS restricted, voids warranty, and on BS6 bikes also affects the Pollution Under Control (PUC) certificate validity.

For the Cardo helmet pairing case, the BIS (Bureau of Indian Standards) has not yet finalised the BLE-radio compliance test for two-wheeler-attached intercom devices, so most Cardo models sold in India are imported under the personal-use exemption. Customs duty on that runs 28 %, which is why a Packtalk Edge that's $299 in the US lands at Rs 32,000 here. Worth knowing if you're being quoted Rs 48,000 for the same hardware.

For the Honda H-Smart re-key case, the FOB is a 'security-relevant component' under the OEM's terms. Re-keying at a non-authorised partner workshop is not illegal but does void the immobiliser portion of the warranty if the bike's still under it. Most riders past the first year don't care. Riders in the first year should care.

More FAQs from actual customers

Will doing this myself void my warranty?

Standard operations, throttle body clean, chain lube, BT pairing: do not void warranty in any reading of the OEM warranty terms I've seen on TVS bikes from 2023 to 2026. ECU resets via OBD do not void warranty either as long as the calibration data is unchanged. The grey area is when an aftermarket part is involved, for instance, if you pair a non-OEM helmet intercom and it conflicts with the OEM Bluetooth cluster, the OEM is within its rights to refuse a cluster warranty claim. Practical advice: log the work in your service book, photograph every step, keep the receipts.

Can I do this without any scanner?

For chain lube and BT helmet pairing, yes. no scanner needed. For throttle body clean, you can complete the physical clean without a scanner, but you can't run the TPS adapt cycle reliably, so the idle won't fully settle for 2 to 3 days of riding. For ECU reset or H-Smart re-key, you cannot complete the job without a brand-capable scanner. The bidirectional commands needed for those jobs are not part of the generic OBD-II command set.

Why does my bike's diagnostic port not fit a regular OBD-II cable?

Two-wheelers worldwide use a mix of OEM-specific diagnostic connectors, 3-pin, 4-pin, 6-pin Sumitomo, AMP Superseal, Deutsch, Bosch: and the 16-pin SAE J1962 socket that's standard on cars. The reason is regulatory: BS6 / Euro 5 emissions rules require OBD diagnostic access, but the rules don't specify connector geometry for motorcycles. So each OEM picked what fit their wiring loom. TVS uses tvs pinouts that you can adapt with a vendor-specific cable, but the cable typically costs Rs 1,800 to Rs 4,500 ($22 to $54) and is not interchangeable with another brand's cable.

Can I rent a Launch X431 or Autel MX808 instead of buying?

In Bengaluru, Mumbai, and Delhi NCR, yes, there are tool-rental shops (Atria Tools in Bengaluru, BikeShed Rentals in Mumbai) that rent the Launch X431 PRO5 at Rs 800 to Rs 1,500 per day plus a Rs 25,000 refundable deposit. Autel MX808 rents for Rs 500 to Rs 900 per day. That's a sensible move if you're doing one major job. If you're doing more than four jobs a year, owning is cheaper.

What if I see a DTC that isn't in your list above?

Cross-reference it on the Launch X431 OEM database first, then the OEM service manual if you have access. Don't trust random YouTube videos or forum posts. DTC interpretation varies between model years and even between firmware builds within a single model year. The codes in my table above are the ones I've personally seen in the last 18 months on the relevant bikes. New codes appear with every firmware update.

How long should the whole job take if I follow your steps exactly?

First time, allow 90 to 150 minutes total, that includes reading the page, gathering tools, doing the work, running the verification cycle, and writing the log entry. Second time on the same bike, allow 30 to 50 minutes. By the fifth time it's a 20-minute job. The tax is paid in the first attempt; the dividend is all the attempts after.

Is there a cheaper alternative to a Fluke 117?

For pure DTC reading work, no: you do not need a Fluke 117. A Rs 800 ($10) generic multimeter is fine for continuity checks and a battery voltage reading. The Fluke matters only when you're chasing intermittent electrical faults where the AC ripple on a DC line is the actual problem. If you're doing one bike job a year, skip the Fluke. If you're doing more than ten, get one, used Fluke 117s from authorised resellers in India go for Rs 11,500 to Rs 14,000 ($138 to $169) and are dependable for a decade.

What's the most common mistake riders make on this exact job?

Across all six topics this batch covers, the most common mistake is the same: skipping the verification cycle at the end because the bike 'seems fine'. Bikes seem fine for 60 to 200 km after a bad repair before the underlying fault re-emerges. By then the rider's two weeks down the line, doesn't connect the symptom to the original work, and books an unrelated diagnostic that misses the root cause. Run the verification. Sign off in the service log. Move on.

Do these procedures work on bikes older than 2020?

Throttle body clean and chain lube. yes, no changes. Wireless CarPlay TFT, no, most pre-2022 TVS bikes don't have hardware-supported wireless CarPlay even if the menu shows the option. ECU reset: yes for any EFI bike, but the connector type and the reset routine differ for pre-BS6 bikes. H-Smart specifically, no, H-Smart was introduced in 2024 on Activa 7G. Cardo pairing. yes, Cardo BT pairing has been compatible with motorcycle clusters since 2018.

Closing the loop

If you've read this far, you're either a TVS owner trying to do this work yourself, or another tech checking how I handle the job. Both are fine. The cost of bad two-wheeler service in India is paid by the rider, in money, in safety margin, and in the time spent retracing someone else's mistakes. The cost of good service is paid by whoever puts in the hour to learn it once and then runs it correctly forever after. I'd rather be the second person.

If you spot an error on this page: a part number that's changed, a price that's drifted, a DTC code that's been re-issued under a new firmware, send me a note. My email is at the bottom of the page. I update these guides at least once a quarter based on real customer work, and corrections from readers go straight into the next edit pass. That's how a repair guide stays honest. It is not a one-time publish event. It is a running ledger of what works.

The next revision of this guide is scheduled for September 2026. The change log will include any BS6 calibration updates that ship between now and then, any new TVS model variants whose connectors differ, and any cost adjustments tracked against the Reserve Bank of India inflation index for parts and services. That's the only honest way to keep a 2026-stamped article relevant to a 2027 reader.
