300ex bogs down at 3/4 to full throttle 300ex Owners HELP
Alright geez please help me here im going crazy here. My 300ex has just recently sputterin at 3/4 to full throttle it has always acted up since I put a 400ex carb on it and I am running a 155 main jet its like when Im hittin top end it starts sputtering and wont stop unless I let off the throttle its like it isnt gettin enough gas or something is clogged but its all clean. I was tryin to see if its jetted right today but had no luck I accidently put a 160 in and it seemed to not sputter as much but it just seams like a 300ex with fmf full exhuast no airbox lid and a k&n filter also to 400ex carb to be running anything over a 155 main please help me guyz
