Having some problems going wot with a bike Im messing with. 303cc stock cylinder, 44mm lectron with pd-1 needle and single feed jet. Seems my needle is set close at least, idle to mid is snappy and clean. Past half throttle to wide open just bahhhhh like a rev limiter, like its too fat. Ran power jet wide open and completely shut, doesn't seem to help. Tried the needle way low and high to see if I could get it to try to clean out but no luck. Other than trying different ignition stuff is there something goofy I'm screwing up ? Is 44 just waaay to much for that cylinder? I appreciate any suggestions!
