I had a new clutch installed by my local shop around two months ago; however, right after I left the shop, I noticed this high pitched screeching sound when shifting into first, I usually don't hear the noise in the other gears. I figured I would give it a few weeks to see if it would settle down but it has not gone away. If I release the clutch slowly I wont hear it, and I don't dump the clutch either. It makes the noise when the clutch starts to bite. I brought it back to the shop and they adjusted the clutch cable and the chain tension, but I'm still hearing the noise. The mechanic said the next step would be to take the whole thing apart, does anybody have any other suggestions before he takes it apart?

Thank you

 

What brand clutch did they put in.

 

They were carbon friction plates, I think from Alto, I'm still waiting to hear back and confirm from the mechanic. https://www.jpcycles.com/product/630...pak-clutch-kit

 

I just did my clutch, i was going to go the Alto route just to try something different. But i did not see much info for them online. So, I went with Barnett, sorry to hear of your troubles, but to be honest, it kind of makes me feel better that I changed my mind.

 

 

I put an energy one clutch in mine and it would squeal some on take off. I changed to a Barnette Kevlar clutch and no squeal what so ever. Some say the squeal doesn't hurt anything. it was aggravating to me.

 

Thank you! I'm assuming that is the case here (I hope I'm not wrong), I was worried that it might be damaging something inside. I don't have money to replace it right now, it'll have to wait till next summer for me to do it; will definitely go the Barnett route next time.

 

It's supposedly not harmful, except to your ears and your nerves. Seems to be related to removal of the spring plate assembly.

It would be nice to know if the carbon or kevlar are more likely to squeal. I don't know if you can use the same oil for both and keep that constant.

Looks like Apache Snow has tried both, with better results on the Kevlar plates. However, maybe some others have experience with one or the other and can chime in.

I use Red Line 75W90 GL5 gear oil. It works really great. Neutral is easy to find and the clutch hooks up very positive. I believe this is on Barnett's list of oils to use with their clutches.

 

I did the Energy One and have the same squeal on moderate take off. Super annoying but not enough for me to take apart and reassemble to see if it goes away.

BUT,....the Energy One does rip thru the gears like a champ. Hitting 2nd and 3rd hard at the right rpm is a real kick in the a$$!
