l started my quad one day to take it for a spin to warm it up and it will not stay started if l let go of the gas. Also when l do go forward and then let go of the gas to slow down the exhaust kind of puts. Anyone have an idea on what it might be?

l think l mayt know, the idle might be too low, when its too low the engine cuts when you let off the gas and the engine wont stay gowing unless gass if aplied, you can look in you owners manual to find out how to adjust the idle and make it a little higher
