westygas270 Posted February 26, 2012 Author Report Share Posted February 26, 2012 its looking that way its loud not a small noise, has anyone had problem with clutches on them? Bikes hardly had any use but i got told that the material on clutch goes and they can do it? sounds more than that to me tho Quote Link to comment Share on other sites More sharing options...

pindie Posted March 1, 2012 Report Share Posted March 1, 2012 What oil mix are you running? Do you do road work? Lots of full throttle work? For this to happen something is not right. Most likely a lack of lube or duff bearings from new? I don't know what your carb settings should be but I'd check them out to make sure enough fuel mix is going through the motor to lube it.

westygas270 Posted March 2, 2012 Author Report Share Posted March 2, 2012 carnt remember what ratio it is i use without looking have it marked out have used it on my betas b4 and run spot on to now, nope no road work or full throttle hardly need it from torque of the bike think its duff bearings got to see lampkins in the week to talk to them bout it Quote Link to comment Share on other sites More sharing options...
