My quad, which has probably had no service in a few years, won't start, it just back fires after a few attempts. The air cleaner smells like gas a bit. Anyone know what I should change, check? I suppose it has plugs like anyother engine. I wanna tune it up, basically.
 
Change the gas, clean and gap or change the plugs. Put some octane boost or some sort of fuel additive in it till it runs smooth by itself. Change oil. Chang air filter if dirty. Once it starts, keep it running a good 15 minutes.
