well i am getting my bike back from a race tuner. got the valves and carb done for a whopping 125.00. i did go and get a pilot air adjuster. so all in all i got 150.00. he told me the vales were at 4 thousands, and they should be 15 thousands. the pumper in the carb wasent working and the old air adjuster was gone. (the guy i got it from played with the carb) so i think this should fix all my over heating and no idle problems. so when it gets good here in michigan(like its ever nice) i can race my buddies crf 450(i have a 426) and beat him even badder then i did the last time. so thanks to all te people that replied when i was asking all the nebie posts.
