Some sound coming out of engine after 1st service..!!

Hey Guys..I am facing some issue after getting my R15 serviced..I drove about 600 kms and then went for first service...And after that some sound started coming from engine..its not very loud but still I can feel it. I dont know from where exactly its coming but it feels irritating...I went to the service guys in Yamaha. They did something and then they drove themselves. But sound was still there..They said its normal and it will itself go away...Also one of my friend told me that its pretty normal. And also performance is not an issue..Bike is flying like anything..Not an issue at all...But that sound certainly feels very irritating....So what should I do guys??...Shall I go again and get it checked or should wait for sometime...Although its already been 2-3 days..and now my meter reading is 950 Kms....

^^lol!

ahh!! now i know why sheel would be smiling...
and yeah +1 for video

most probably coming from the chain, not an issue..

Dude, While the ECU cost is lowered so is the Chain. It's 855 MRP now and the whole chain-sprocket kit is 1436 MRP

Well..I went about lubing my chain through the rainy season without cleaning it and 2-3 weeks ago stripped the whole rear end at home and cleaned, lubed and greased everything that needed attention. Bike's running well so is the chain. SAE 90 grade is good, but not for us who ride hard. If one prefers to ride at 40 kph expect the SAE 90 oil to stay on the chain for a bit longer. :P

I'm still using Motul but will test the TVS lube if i can get my hands on it as my Motul can is almost over. TVS Chain Spray is 500ml for 295 MRP sounds like VFM but have heard that it doesn't last long on the chain, especially in the rains. But at the price I don't mind lubing twice as much.

AFAIK Stock valve springs are good enough for the bike. But are you facing anything like the rpms staying at 8.5-9K or a dip in the rpms when you get to your aforementioned rev-range?

Same here, touch wood!

Like Satyen said it, Claim Insurance! I've cracked my rear alloy once and claimed insurance!

TVS Chain Lube is good. I personally found it to last longer than my Motul.

Is it? That's great! Will pick up a can of TVS Chain Spray if i get it in Mangalore.

Damn, missed out on that! You know what? I'm going to get my chainset replaced soon too! BTW, is it still DID manufactured? Or localized? And about the lube, have you tried wurth? It really is worth every extra penny! It lasts longer than any Motul, OKS, TVS, even under high pressure and moisture(read light rains). It even has much more penetrative power in my opinion.

It appears like my bike prefers staying below 9k RPM for some reason. The whole character changes, it becomes more evident when the payload is increased. I previously thought it could be a tappets issue, but re-adjusting thrice also couldn't help much. But I have to mention, there might be some change in spark plug gap(gap got messed accidentally, never got to check it with a guage again..appears okay visually when compared to a stock plug). Also, the NVH has increased a lot.


EDIT: One more thing. The next time you take out your chain, you can actually boil it heated grease, in case your chain is already nearing its end and the links are getting jammed. This way the grease'll get back into the rollers, and the links will get unjammed too...that's one way of reconditioning a bad chain!

I'm still using the old one. Next visit to the SVC i'll look it up. But I think it's localized now or I remember being told. Will update you soon. And I don't get Wurth chain spray here or rather my attempts to locate one has gone in vain.

You should have replaced the plug immediately instead of fiddling with the gap. I've replaced mine twice at 10K kms each, not that it was required but I prefer my bike running at optimum conditions as possible. The old ones are in a box along with other spares.

Speaking of tappets, I've never checked mine, neither valve clearance. 24K+ kms and no loose tappets. I think my clearances are fine but will check them at 30K kms.

I've replaced my radiator under warranty although I've had no issues ever but there was the radiator replacement drive so I got it done.

Valve float on a stock bike is unheard of and will need to cross check this one.

Good idea regarding the chain, i had thought of it since the last cleaning session but i don't think i'll be allowed to boil the chain at home. Will have to get new utensils along with a load of grease lol! My chain still has some way to go but i think i'll get this done in december when I have more time to do this again and replace the sprocket dampers along with it.

I replaced my chain sprocket on saturday of last week. Its still DID manufactured. Bought it from a Yamaha Authorized Service Center in Vashi, New Bombay. The cost printed on the bar coded price tag was Rs 2110 for the chain. The rear sprocket was a lil over 300 bucks. The primary sprocket (front one) cost Rs 270.

Someone had quoted the reduced price. So i might have got one from an older stock inventory. Not sure

On a separate note: Post 14,000 km here are the changes that i got done.

Disc pads, front and rear. Chain sprocket, engine oil Motul. However at 12k km i had got my clutch plates replaced as they had worn out. I ride the bike everyday in heavy traffic. Now i got these changes done through a local and what i'd like to describe as a reliable mechanic. However at a lil less than 14k km, the pick up has gone down and it already feels like the clutch plates have worn out.

We thought there was some problem with the fuel tank, fuel pump so we opened those up and got those checked. No problems there. The bike doesnt miss a beat, misfire or there is no drop in RPM in a jerky manner when accelerating. So i'll go with the assumption that the fuel system is fine. FYI: I've been only using Speed, or Extra Premium or Power and some times Speed 97.

Could my new clutch plates have worn out so fast? Has the mech done a faulty clutch plate replacement? What could be the possible way out? I've been getting the bike serviced outside the service center since i got it because of a bad service experience with my previous bike with the authorized service center. Should I get the clutch plates changed again? Also I find the clutch push rod near the engine a bit laggard with its tension. Could that have caused an improper clutch usage?

What do I do guys? Any or all help will be really appreciated.

Oh sorry, my bad. Will check the prices myself. Thanks for the info brother

Do you stay in three figures all the while? During the 150kms I mentioned, I stayed around the 70kmphr mark.

Hmm but a dry/unlubed chain makes that irritating chakk-chakk-chakk noise.


Well 40 kmph is a bit too low. I prefer 70 for commuting. And please post a thread in the DIY section regarding the stripping of the rear end. I want to know how to adjust chain slackness and how to access the front sprocket.


Guys, you should also mention the risks involved in the procedure, viz-a-viz mom kicking you out of the house for greasing up her utensils. :P


Is this available at the TVS Authorised service centers?

how many teeths are there in R15 sprockets???

First off, Clutch plates replaced at 12K kms? How did you contribute to make that happen? I find it shocking that you've had your clutch plates replaced so soon. Any why a local mech, mumbai must have atleast half a dozen dealers and atleast one authorized SVC competent enough to carry the works on your bike or atleast diagnose the exact nature of the problem.

The chain you bought is from the old stock.

Also it's waste of money to use high octane fuel on the R15. It does not have a high compression engine.

Get used to the noise, it's a characteristic of the bike. You have to live with it. It's not an issue.

DIY will have to wait a bit lol

No issues if your folks are used to you turning your parking into a makeshift garage on the weekends

AFAIK, Yes it's available at TVS SVC.

Front: 14T
Rear: 42T

oh yes. two of them actually. both 2008. one was pathetic. trying hard to cross 125. it was extensively used for stunting and was abused hard. but the irony is that it had only clocked 18000kms. the other was strong. clocked more than 30000kms and maintained properly. but that bike was too ridden fairly hard. the thing here to notice is that proper maintenance goes a long way.

mine has clocked more than 7000kms.

I do agree with u on the marketing part, but 3bhp was a LOL to me over there, but i needed to get down the price so i kept quite.

Poor guy, let someone do the SIN and get him buried(some day 4 sure). He is the only nearest authorized dealer in the city, the other two dealers are just too far away so i was forced to go to his shop.

This is just a KN, no ever comparison with a DAyTONA KIT. I just felt a bit of initial pick up and high end torque is OK nothing much.

With KN, the pick up is a bit more, the revs were faster than the stock. And nothing to much finally the roar was good thats it.

Guys by bike is done 13k on the odo, should i need to change the tyre now? mech said that it will run 3k more kms but i feel somewhat the threads have just started dissappearing.

Thats great ... Will have to check with BPCL bunks if they have started stocking Speed 93 again ...
I sure hope that they do have it now ..
