What's the life expectancy on a set of cush drives, on a street-only bike? I've got a '97 m750 and I just put a new sneaker on the rear end this weekend (Pilot Powers - w00t! w00t!), and I noticed that I can compress the sprocket by hand - which I'm not sure whether I should be concerned or not? There's no rotational movement, but I can decrease the gap to the rim by pushing on the sprocket. It doesn't touch, but I'm just curious what I'm looking at here. Should there be some compression room? Am I still good if there's no real rotational flex or slop?
I don't stunt the bike, but I certainly ain't driving miss daisy either; we're at 38k miles, and AFAIK
, these are the original bushes. I know these don't exactly pop out with a smack on the back either ... what am I looking at in terms of replacement/maintenance, anyone?
Thoughts/suggestions/advice greatly appreciated!
