    I have now run in my bike and still find it running a little hot. The fan is on most of the time. Is this normal? I remember soemone Perce possibly telling me to change the jets from stock to something else but can remember the numbers. Can anyone help? The bike is also very sharp which I thought I'd get used to and would soften with time but now I want to soften it myself. How do you retard the ignition on these bikes and are fly wheel weights available and worth adding?

    My clutch is dragging on my 01 280 to the state that I can't find neutral at all before a section. Pretty easy when the bike isn't running, but a little embarrassing. I've seen the comments on the US Gas Gas site about measuring the clutch plates and that they expand. The problem I have is I don't know where to start. Give me a Haynes manual and I'll work it out (or hit it with a bigger hammer!) How easy is it to open the cases, check the the clutch plates and replace them or do I need to take it into a dealer. All the best, Rob.

    I have an 02 Pro 280 that is set up wonderfully.. Everything is perfect EXCEPT the clutch has become very hard to pull at the lever... it operates well, it just fatigues the hand. Knowing how the clutch operates, I have my ideas about why it has become hard to pull. Does anybody else that has knowledge of this clutch have some thoughts? A hint about what I think is going wrong: The "spring" (which is actually a "ring") is the culprit. What do YOU think? I'll be calling the "parts house" first thing tomorrow and ordering the necessary items.. a ring at the least, an entire clutch pack at the most.. . thanks, W

    I finally removed the muffler bracket on a GG, annealed it to be safe, and bent it to a nice "s" shaped offset, and the tire no longer hits the muffler. For the time being... Replaced the rubbed-off rivets, too. 5/32", I think.
