well heres the problem....me and my stepdad has been rebuilding a outlaw 500 and we got everything done and tried to fire it up and the timing seemed to be backwards....??? it sucks through the exhaust and blows out of the air filter.....i tried turning the cams 180 degrees thinking that was the problem....but that didn't work either...i've tried timing it like a dozen times with no luck at all so any help or ideas would be greatly appreciated....this is the first time i've worked on a dual cam quad so i'm learning as i go.....thanx......
