i have a 16t z1000 front sprocket and stock rear.
the sprocket and chain have about 2500 miles on them.
i am going to replace the chain and rear sprocket up a couple teeth.
question is...do i need to replace the front sprocket also due to have a little wear on it. my friend was telling me you need to replace both sprockets and chain all at the same time so it wears even. is he correct?
another question about the front sprocket. i was thinking about going to a 520 conversion, but i dont like a lot of noise. the z1000 front has the rubber buffer around it that keeps it quiet. how much louder would just a standard steel front sprocket be? is there a big difference in chain noise, or is it something barely noticable?
This is a rather loaded question because..it involves what is wear, how is it detected, what does it do.
And what is the price paid, on what happens to your chain and rear sprockets life?
Thing is, if you had higher mileage, jump out and bite you visable wear, on the front sprocket, it would be a clear cut, slam dunk, no two ways about it issue.
Problem is, say .003 (thousands of an inch) wear is not seeable, but to the chain it is shifting load bearing progressively away .003 -.006 -.009 -.012 with each tooth engaged. This over loads the chain roller, hastens the chains getting "stretched", stretched chain hastens the wear on the new sprocket.
Lotta Yammering to say....go with your friends suggestion, Your just talkin the price of a front sprocket.
