I just bought a 99 yz250 and it is going through spark plugs like crazy... It seems to run fine, but after about 30 minutes it just up and dies... Inspecting the spark plug, the end is completely black...
The throttle response seems good and power is very snappy... It "seems" to flatten out a bit at the top of the rpm range, but I'm not sure how it is supposed to feel as this was my 1st time on the bike. It does have a pro-circuit pipe and silencer on it... I am a total noob and don't know a thing about tuning carbs... Any suggestions??
thanks,
Brian
