I'm sure some of it has made it on my rear tire. There is quite a bit on shock links. So far I don' t think there was enough on the rear tire to be a real hazard, but obviously it will only get worse.
I've decided to get the seal kit from Murph and just replace them. As much as I like the though of the 7th gear, it is just one of several up grades I'd like to put into a bike that, ultimately, I'll no keep forever. I've had this bike since new in '04. I'd like to do the 7th gear mod with exhaust gear and 2mm jet kit, Kossman rear tire, and Russel Day-Long seat. Ok, start adding all that up. As much as I like this bike, I just can't see dumping close to $2k in mods into her. No, I think I'll just change out the seals and drive her until one day I get something different.
