Knot, I'm pretty sure it's coming from the front sprocket. I didn't install it or ever have it apart, so I'm not sure what all is involved. Everything seems OK at the moment. I don't notice any difference except for the noise. It kinda sounds like every other open primary right now. The Baker was always quiet. That what I liked about it.I'm wondering if your clutch disc fingers are wore bad enough to cause the sound your hearing...I have had MastiffDaves baker off his bike 2 times working on it...he didnt have a clunking sound it was more of a clinking sound if that make sense...what I found was the clutch disc (fibers not the steels) had enough wear on the ears that it was making a clinking sound...I put new clutch in it and it fixed the problem
