Why is my Kymco Maxxer 300 quad on a 07 plate having starting problems?

take your carb out, clean the entire thing, that means every nook in that *****. do this and if still a problem write back because in most cases were n idiot is involved, this is the most over looked problem

get a can of starter fluid and spray a short burst into the air intake...it should fire up...if it won't stay running or idle your carb is clogged from storage i presume...right? usually storage for more than 3 mos will clog a carb if you did not winterize it...Good luck to you friend...Tim

A service manual is a valuable tool with an aging bike. I suggest the dealer/mfr. or Clymer books. In the meantime, go to the library reference section...646 stacks should have what you need.

I see: you changed the plug because it was backfiring.

Does it back fire when you let OFF the throttle after revving it, or does it back fire while being revved?

If it does it when you let off then Ollie's suggeston might do it. If that doesn't do it then check for dirt in your pilot jet.

If it back fires when revved up high could be dirt in your main jet.
