Hello, I'm helping a friend out with a 02' Bear tracker 250, It doesn't idle well until its FULLY warmed up and it also has a glowing red header if ridden hard so I figured id adjust the valves just in case- but Yamaha does not publish the specs in the Manuel. Does anyone on here know the valve clearance? Is the glowing red head pipe normal, it looks like the same thin wall pipe my friends raptor uses?
Thanks, Joe
if its glowing the pipe chances are the timing is out . take out the big allen nut on the reverse lever and take the cap off the head on the left side of the head and bring piston up to top and check timing marks , being a 250 it probably has a worn camchain or tensioner and has slipped .
was it the timing that was making the bike idle bad. i have the same bike and it does the same thing. i don't know if i need to adjust the valves or the timing
