My '97 XR600 seems to be making a sort of honking sound in second gear, especially when off the trottle under engine breaking. I can't think of a better way to describe it. It's not very loud, but noticably different from the other gears. It's been doing it since I bought the bike about 2 months ago. The sound doesn't seem to happen in other gears, so I suspect that it's not a general engine problem, but that something is up with 2nd gear specifically. Other than this sound, the bike runs great and there's no trouble with shifting or otherwise. Obviously, this is not a good thing, but I have the following questions to ask of anyone who may have experienced this... First, if you've experienced such a thing, what was the outcome? Second, is this an imminently fatal problem where my gearbox could explode and rip the case apart at any moment? Or is it one of those deals where something is just beginning to wear and I can ride it for a while before it really needs attention? Not sure how "nervous" to be about it. I'd appreciate any input and person experience you all can offer! Thanks!
