160,000 miles on a bike, is that possible? lol Well I guess it'll never matter if you don't plan on selling the thing.
Sorry I can't be help with it, I just found out yesterday that bikes have adjustable suspension and the guy I'm buying my bike from explained how it all worked, pretty cool.
Do you have previous experience riding? I've NEVER been on a bike before, lol, so I've got a lot of practice and need to get more comfortable on one.
Are those bikes carb'd or fuel injected? Mine is carb'd but my buddies is fuel injected, other than the tuning pros', I didn't really see a difference in them. I mean I've gotta play the choke for 30 seconds or whatever, but big effin deal.
