Hey guys... I'm buying a 93 ZX-6 off a friend in the next little while. We've got the price pretty much agreed upon, but there's one thing I"m not sure about. The throttle doesn't return by itself, you have to manually turn the grip back to back the throttle off. I figure it's probably a problem with a spring or something (never had experience fixing bikes) and that it'll be fairly easy to do myself. BUT I just want to be careful that it isn't a problem that will cost me big buck to have fixed in the long run. Any input? Thanks!
