Hi there,

I have a strange clunking sound that seems to come from the back wheel somewhere...maybe the front sprocket but i doubt it.

Happens when I pull away in first gear but it doesn't happen all the time?
Seems to do it when it starts delivering power to the back wheel...or on a incline
when you pull away twisting it a bit more vigorously....  ???

Doesn't last long...I would say when you get to 3500 rpm it's gone.
Almost like pulling away in second gear except the noise is from the back wheel.

I took it for a 10K service at BMW in Pretoors and also had them change the
tyres...
I don't think it's wheel bearings as the wheel doesn't have any play on it when you wiggle it. 

Any suggestions/idea's would be appreciated!
Will go around the block this afternoon without helmet to hear if I can hear better...!

Thanxs!
