What do you think is rong with my r...?

Ok on top end it cut out just DONT rev high, and about half throttle it pings... we have messed with everything, its either my piston, like rings or sumthin, my reeds, they might be torn or sumthing(kinda dougt that though) or my CDI. In my manual thing it says that my CDI I can cause this, maybe its going out? What do you guys think? its not my jetting!;) :mad:

is it a new engine? if it runs good jsut off idle then pings and then cuts out...thats a for sure sign of being lean on the main.

Its a fairly new engine, and trust me its NOT the main jet!;) It was perfect.... I dunno what is the matter...:( :mad:
