I'm sure your set up works great in the right application. I'm using a stock Magnum E50 that is ported. I made the transfers open (finger ported) and...
it wouldnt idle with a 51 slide and 2.22 atomizer. With a 51 slide and 2.17 atomizer it idled great and had ok low/mid but with the midified 24 its real nice, pulls as hard as a kitted bike up to 25mph.
It wont rev with the one ring needle.
The only problem it has is that at wide open the exhaust sounds like its farting and it stops reving, about 28mph, it will pull through it to 35 then stop reving (the pull is slow). If I have a slight down hill it will pull to 40 then if the road gos flat it will hold that speed. I dont know, I might make a video and start a new thread. Maybe squish or ring flutter (pulling this out of my ass, I dont know). Jetting richer or leaner wont help, timing is at 19ish mm of flywheel rotation with CDI, maybe a bit much but with the finger porting the cylinder runs so much cooler its ok. BOSS pipe.
