Re: Modified Final drive?
Don, I was worried from day 1 (that being the day I learned I had bought a bike that was reported to have a FD problem). I have an '01 with just short of 80K on it. The PO, GoldenDragon, said that a dealer had done a pre-emptive FD rebuild just prior to the expiration of warranty. I lost my rear main seal at 68K, and tore the bike down for that. Since I had it apart, I thought it would be a good time to just peek inside the FD for an inspection and because I just wanted to see what was in there. That's when I found that my bearing retainer was broken in 5 places.
I used Curtis' video as a guide to rebuild mine, and discovered, as he suggested that I might, that I was over shimmed by a wide margin. Likely the dealer that rebuilt it at 30K simply replaced the bearing and stuffed the old shims back in without measuring.
I'm now a firm believer is taking a peak. It's really not that hard to do.
