does it sound the same and just looses power or does it pop and fart around ?

does it free rev cleanly ?

its sounds ok bottom end but more than 1/2 throttle it breaks up

try some spark plug caps they are cheap and are know for faulting over time. when you change the caps, cut about a 1/2" off the end off the coil spark plug wire and screw the new plug cap on.

check the normal stuff like pick up gap on the fly wheel (.017"-.020") and coil resistance.

 

have you tried any other jetting and needle positions ?.

I've ran CPI's on a stock shee and they ran great...

 

Maybe those 300's are too rich, so its choking on fuel at WOT?? Just a guess Do a plug chop
