hi i have an 02 honda trx 400ex bored .26 over and it wont run on top end does any one know what could possible be wrong if so please let me know!i hade it at a dealer to get fixed twice and it still aint running
Sounds like a jetting issue to me. Does it do it if you slowly accelerate up? Or only when you rip on it? I mean if you just gave it say half trottle and slowly got going fast does it still bog in the top end?
