I have another problem with my 2002 Honda Forman 450. I just developed a shift problem where it will not shift out of 1st gear. It is a random problem. Sometimes it will shift to 2nd and other times it does not. I don't know if this matters but I can shift through all gears if I am sitting still and just idling. It is only when moving in 1st that it will sometimes not shift to 2nd gear or higher. I don't know if this has anything to do with my speed I'm at when trying to shift. I made several repairs to the ATV since I got it. But my knowledge of transmissions is extremely limited. What would cause the ATV to not shift out of 1st gear?
