2002 yamaha bear tracker 250???
I have a 2002 yamaha bear tracker and cant seem to find out the problem.... i had the head sent out a few years ago to get rebuilt and finally found time to put it all back together after cleaning out the carb and putting everything back together i found out that it will start up great with or w/o choke cold or hot and it will idle great as well. But when i start to ride it it will start bogging out at 1/2 throttle or more and when i back off to 1/4 throttle it sometimes helps but it will also sometimes bog. It's like it cant carry any wait on it or go up hills, going down a slight hill it will go but other than that nothing. it would be great if someone could give me an idea of whats going on thanks.
