I had the same problem with mine I only got to ride it 5 minutes and the cdi box went out of it. Id take it back to them and tell them to put a diffrent cdi in in it and see if that works. It sounds like you have the problem I had.

Just an update found reason does not start no compression.Cked compression do not even have 20psi. Thanks to those replys

if your quad has not run in a while, the constant tries at starting your quad will eliminate compression......no oil. oil helps eliminate the gap between the rings and cylinder wall. that could be and probably is why you are getting low compression numbers.

what did your quad do when it stopped running? if you parked it one day and the next it didnt start, chances are it is not a piston. If you were riding and it started losing power AND THEN didnt start id say it was a piston.

good luck..
