Idle RPM is set to 1.5 - 2k but it also has stopped at times at around 2.5 - 3k

^^Even am facing a similar issue as Vineet when I ride, but my bro claims that its perfect!!!! Will have to try it out for a longer duration and verify it.

You are facing the same with an FI or R15?
i don't c how a stalling engine could be perfect but sure does scares you when these things crop up on a 2 week old bike!!

I have an R15 and my brother has an RTR-Fi Its done 3K kms. I think this issue is more related to the summer temperatures. Will have to spend some time to understand the issue.

Oh Ok!! Thats a racing family right there anyways do lemme know if something comes up. Even i would be giving my bike for servicing in a couple of days. Lets c if they have any kind of opinion on that.

Any particular things to look out for during the first servicing??

the SC guys changed the FI unit on my bike. The problems I reported were bike turning off for no reason and missing power arounf 3k-4k rpm (only sometimes).
but even after replacement, the issue of switching off persists.

it's generally hapeneing when the bike is run to 10-15kms....and if the bike is parked in sun for long...
thr are some issues in FI tht has no reasons....
here in this thread we call them the "CHARACTER" of the FI!!!!!!!

..................

i think now it has become the signature of the FI!!!!!!!

"CHARACTER" of the FI

Even I'm facing the same problem....

Idle rpm : 1300 (+/-500) rpm

Pick-up almost dies in rpm band of 3K~4K.. and the bike moves creepily....
Even 0-60 best timing shot upto 5.2sec... whereas my best timing was 4.1 sec...
I feel like I'm riding any ordinary 100~125cc bike....

I was thinking of related causes:

Faulty FI, faulty fuel filter, choked air filter, lean mixture, engine oil...
Any more causes pls add.....

We have to do something cohesively about this.

@renny

while it's nice to inject humour into any situation the character joke is getting a little long in the tooth. these people are troubled by rather serious issues and come to the forum for help. let's just try and help them without cracking poor old jokes. and btw, it's a characteristic of the engine, not character. and there are no issues without reasons. it's a machine, there will be a technical reason behind every problem. and it's tvs's responsibility to solve each and every one of them. time poeple started demanding their rights. missing power, erratic idling and random switching off are NOT trivial issues. It could even be life threatening if the engine just switches off in the middle of a busy highway.

i should feel lucky, i dont have any of these issues. not a single one, no matter how hot it is. well, there is a general reduction in power when the engine is very hot but i guess that's normal in any performance bike. my rd had that too. the very day i bought my fi, there was a choking problem; fuel not getting to the engine at higher revs. turned out the petrol pipe was too long and getting constricted under the tank. when a shorter, proper length pipe was used, the problem disappeared. nothing ever since.

hey pal please understand YOU don't have to do anything about the problems. TVS has to. What we have to do is make them do it. i would suggest following aparajith's example and writing to tvs head honchos.

i can't help it if english is a problem ... anyway, the point i was trying to make is that instead of trivialising these issues into a joke, we should be getting tvs to solve them. not accepting them as 'came with the bike' or 'standard accessories'
i'm probably one of the unluckiest persons out there. just think, would all the fi owners who don't have any issues with their bikes come out here and post that they DON'T have problems ? no, it's just the ones that do who will post. i'm sure there are plenty of FIs out there without any problems.
well then it's obvious that the FI unit itself was not faulty. regardless, tvs HAS to solve the problem.
we would all like to know the cause of the problems. but even if a person isn't so inclined - hey there may be someone who just wants to ride the damn bike without knowing what makes it tick - i'm coming back to my main point that TVS must fix it.

well, ignorance is bliss i guess. i did say performance bikes. the fiero was a very relaxed tune and would probably run for eternity without as much as a whimper. i actually do know fieros that have run for ages. and you're kidding about the more heat=more power right? just because YOU don't know something doesn't mean it aint true. it is common knowledge that overheating reduces power. an easy (relatively) way out with 2-strokes like the rd was to optimise the squish band so more heat could be transferred from the hot piston to the cooler cylinder head. also the incoming charge also helps cool the engine. one of my theories is that due to the fi, the charge isn't cooling the engine enough. i don't talk about what i don't know dude. suggest you try the same.

It may seem to be idiot question . But can anyone tell me how to perform stoppie? plz. give me step by step procedure. i tried doing it on my RTR hile braking 60-0. however i brake hard, the rear gets lifted by hardly a inch. shall i have to give jerk or something, shall i initiate braking progressively or how? there is no problem with wheelie and burnout. plz. help buddies.

Hi guys,

I got my first service done a week ago. Here are some issues I'm planning to report to the SVC guys on Monday -

* I feel a loss in power and acceleration

* Engine misfiring. When I take the bike to 60kmph, release throttle for 1-6 seconds and twist the throttle again (however slowly), engine misfires. Sometimes even at 50kmph. I'm able to reproduce this every single time.

* Today was the first time my bike got wet in the rain. When I reached home, I noticed that the idling rpm had gone up from 1250 to around 1750! How is this possible? You think the rain caused this or just some mischievous guy meddling with my bike's idling setting (how do you change this in RTR FI, anyway?) ?

You guys think there's a possible connection involved in the above 3 issues?

* There's a kar...kar... sound from the rear (like twice every rotation of the wheel). Sometimes this happens, sometimes it doesn't. The sound is VERY noticeable at low speeds (~20kmph, when I'm slowing down my bike to park it) and embarasses me and my bike by making everyone around look at us. I'm not able to tell if its from the wheel or the chain. Any of you faced this problem before?

Thats about it I guess... will post again if I remember anything else. Any input before Monday is appreciated

check with the engine oil level & quality. svc might have not topped it well resulting in heating of engine and high rpms.the kar kar sound must be from chain they may have not lubricated it and slackness would insufficient(it must be 3-4 cm). if its not chain, check rear disc for uniformity a bang of hammer may distort it at time of service. its my experience, the chain slackness kept by svc on my rtr was 1 cm. they didn't lubricated it. engine oil added was 800ml and of 5W30 grade. On Fi, the rpm is controlled by ECU. it runs faster because of heating. and yes, check throttle free play also.

guys there is one problem.
when i run in a bump,my head(bike :P) makes a sound like khat khat,like if something is loose. but all the nuts are well tightened.
what could be the problem?


S

you need to tighten the check nut of the handle.
