2006 ltz 250 carb wont rev

[krashtopher]

every time i let this bike sit for awhile the bike will start but wont rev. the only thing that has worked is taking it to the shop and having it professionally cleaned out with ultrasonic cleaner 150.00 : ( really?? is there no other way to keep this thing running more dependable??

best thing to do if you let it sit is to put stabilizer in the tank, turn the gas off and empty the carb bowl. stale gas is the worst thing for a carb ,,,
