OK got a problem to be diagnosed (by the way its not my banshee, its one at the shop) Ok, banshee just got a new top end, compression is good and everything, when you start it up it idles fine, but you revv it up it starts popping reeeeeally loud, and sputtering. we put a new CDI on it and it still does it, its not sucking any air and theres no broken reeds. I thought maybe a problem with the magnetic pickup??? Im gonna take all the electrical stuff off my banshee and try it on this one. any other ideas?

 

90% of the time when a banshee has a problem its due to the jetting/carb issue.

 

Yeah, give us a little more info... And hey I just checked out your photo's... What size carb's are you running? That's one sweet Banshee you have there!!!!![img]i/expressions/face-icon-small-smile.gif[/img]

 

How far did they advance the timing? Is your keyway sheared any?

I think it is a timing issue!![img]i/expressions/face-icon-small-smile.gif[/img]
