Today I installed my two new JT sprockets and DID chain. Needless to say, I needed them - I hadn't really taken a close look at the rear until today
The front wasn't nearly as bad - looked just a little worn. Both were JT, so not original. The new DID chain is marv. Cleaned up back there while I was at it.
Any secrets on those funny little washers holding the sprocket nuts in place? I considered painting my sprocket cover, but after beating the heck out of it bending those washers back into place, I'm glad I didn't bother.
