4-stroke Dirt bike not idling.?

yes it is typical with any bike weather it's 2 or 4 stroke...if you don't ride it and leave old gas in it for a long period of time then it will do that...an easy fix would be to get out there every couple days and fire the bike up and rev it up to clear out the carb and circulate the gas through...you might have to go get gas again to ride it but it will save you that hundred bucks....and yes there is...you don't put it in the tank though..it's a can of carb cleaner that you can spray into the carb that will clean out the carb...and you don't have to take it apart to use this stuff....i've had alot of luck with it....
