alright, i'm thoroughly confused on this one. I've read up on jetting and feel like i have a pretty fair grasp on the concepts, but i haven't messed around w/ my quad yet, because i don't want to do anything until i know for sure what i should change.
okay, initially, i could rev the bike (300ex) up to wide-open SLOWLY, and it would reach the top end. But if i would punch half throttle, it would stutter and die. Then, once the engine warmed up, i could punch half throttle, and it would stutter but then rev up.
I drilled two holes in my airbox to see if better airflow would help. But instead it's even worse. Once it was started, it wouldn't go above idle. it owuld just die. And i could actually feel it pushing air OUT of the hole in the airbox lid. When i covered the holes up, it did the normal thing that i talked about earlier.
what does it sound like i need to do? i'm a roast. baste me.
