discovered while cleaning chain...

Thanks guys. I wouldn't doubt the PO mixed and matched parts. It would not be the first silly "fix" I have found.

Interesting kawasaki.com says a D2 rear sprocket is 40T. Because mine FSM says it is 41T, which is what I have and it appears to be in great condition.

I'm going to take some more measurements and get on the phone with Z1 monday.

Interesting. Does your manual give the size for the countersprocket? Ed

Final reduction ratio = 2.56(41/16)
Overall drive ratio= 5.81(@top gear)
