How many kms on your ODO bro, it would help if you can elaborate what your vibrations are like, is it from the split handle bar, or the shockers... what did SVC say about it?Originally posted by veyron999 View Post
This seems to be your brake pads. While touring there are many dust particles which come in contact of the brake pads and which rubs on the disc plate and they make some noise. A pressure water wash on the front disc can help in making you sure where this sound is coming in. If it goes then it is the disc pad, if not then its something else.Originally posted by veyron999 View Post

1) My rpm is different at ideal condition. When the engine is cold it shows 1.5K and when I travel for sometime its around 1.1k. Is it normal? I am at 635km by ODO.
1.3k when the engine gets hot is normal. Cold start rpm may be around 2.5k too. That is normal.
Edit - This is for 20P1 series.No.Possibly, but the effect should be negligible with slime.
Thanks in AdvanceAbhimanyu, I tried this and found that the sound is not at all related to speed. For all gears, the sound will peak at 6k rpm only! If I pull in the clutch, the sound mostly disappears. And higher gears or greater load increases the sound level by a bit. It is not very noticable at lower gears (1st & 2nd) and gets almost irritating by 5th & 6th.Originally posted by abhijeet080808 View PostI will pull the clutch in while riding at at 6k rpm and see. AFAIK, it mostly goes away with the clutch pulled in.
Also, noise is more under load - say climbing a flyover.
Performance is fine, no vibes too. Just that it makes me rev above 6k rpm to ride comfortably!

Is this the clutch bell issue or is it something else?Last edited by abhijeet080808; 05-18-2011, 11:09 AM.Your biking tells a lot about the person you are!

1. no the rpm should always increase in 38B1, the cold start rpm may be 1100rpm bt after the engine warms up it should be between 1300-1500rpm
2. do your home work and go through the manual, everything is written there.
3. by liquid if you mean slime, then the answer is NO. if you talking about any other liquid then I dont know
Yeah it is the Clutch Bell sound only which is quite common, how many kms on ODOOriginally posted by abhijeet080808 View PostAbhimanyu, I tried this and found that the sound is not at all related to speed.

alright bro, 20P1 has more vibrations than 38B1 specially of the clutch bell. Well if you feel that the sound is way more than normal, then you can go to the SVC and tell them to check. May be they will open the clutch plate, clean it and fit it again. SO check with them and keep us updatedOriginally posted by abhijeet080808 View Post11k done as of now. Its a 20P1 model.
Thanks for the confirmation!

The clutch plates needs to be cleaned? Did not know about this. Anyways, I will be replacing the clutch bell shortly.Originally posted by Shivanshu View Postalright bro, 20P1 has more vibrations than 38B1 specially of the clutch bell.

If I recall correctly then your bike has done about 11K... there should not be a problem for atleast another 10 to 15K... I suggest you wait for another 5K and observe if the sound is increasing... if it is not then don't waste money because after you replace the bell, the sound will most probably come back in another 10 to 15K...Originally posted by abhijeet080808 View PostThe clutch plates needs to be cleaned?

As of the cleaning the clutch plates; it not exactly cleaning as the plates are immersed in a oil bath which keeps the plates clean by suspending the particles that break off due to friction of the plates... what it is normally done is that when you open clutch plates, if glazing is observed on the friction material then to break that glaze sandpaper is used. This is old practice which I really don't know if its really relevant now.Only a biker knows why a dog sticks his head out of a car window.

I have been observing the bike since I got it at 5k kms. It has been increasing slowly ever since. At 5k kms, it just felt like a slightly rough chain. Now it is mildly irritating at 11k.Originally posted by abhimanyu31 View PostIf I recall correctly then your bike has done about 11K... there should not be a problem for atleast another 10 to 15K...

Now if the new clutch bell exhibit the same issue after some kms, I wonder if there is any good in replacing it. How is it on your bike?
The bike has been smooth and silent except for this. I am also planning to install Joel's Big Bore/exhaust. I guess after that this sound wont be audible enough to bother me anymore.
As for the cleaning, that procedure does not sound like it can decrease the sound.Your biking tells a lot about the person you are!

My bike too has the same noise... I was going to change the bell and even bought the clutch bell... then I discussed it with Joel and his recommendation was leave it as it is... I have no problems with the bike, its smooth, fast and very responsive... it just a sound which you will get use to... so right now I have not changed it... I did open the clutch (my bike has done 11K) to replace the springs with the heavy duty ones sourced from Joel... at that time I took a look at the clutch plates and found them to be in very good condition with no glazing at all... thats why I said that I really don't know if this old practice has any relevance now...Only a biker knows why a dog sticks his head out of a car window.

^^^ makes a huge difference... the lever action still requires the same effort, that has not changed... what has changed is the feedback that you will get when you engage and disengage the clutch... it allows for more precise shifting... also another thing that I noticed in stock bike (maybe its one off case with mine); during high speed runs if you are facing stiff head winds the clutch has a tendency to show some slippage, this was exasperated even further with the big bore kit... all of that is gone now... I would recommend these springs even for stock bikes...Only a biker knows why a dog sticks his head out of a car window.
