So I bought a rear JR sprocket for my 96 xr600r that was listed as the correct sprocket. I went to put it on and guess what?? The bolts I currently have are not tapered. So, is this just a simple fix of buying a new set of tapered bolts (as long as the holes in the sprocket are on the correct center, and the diameter of the bolts are the same, I should be OK)? If so why are the ones I have now not tapered? I'm replacing an aluminum sprocket with a steel one.
