Well, My Y2k and my buddies 99 both make a lot of mechanical noise on cold start ups, not knocking, and not clattering, it sounds like it is coming from the tensioner area, he has done the recall on the 99 and it still makes noise, his bike has like 6k miles and my bike has made the noise since day one and though it does not seam to be getting any worse,it only does it cold and at slow idle, once it is warm, it is fine, no noise whatsoever. After reading all of the failures on the board, now I am thinking about it. I have 4k miles and am ready to start taking some trips and I do not want to worry about driveability. The bike is about to be my daily transportation because my 99 Formula is going in for warranty work(blown 6spd)so I don't need the bike to take a dump when I need it most! How do the manual tensioners differ from the stock? I don't want to have to be adjusting it all of the time nor do I want to void the warranty by having a manual tensioner.
