I am needing some advise, I have an 04 with some mods, hetrick pipe, 24mm carb, uni filter, it is a 52mm bore I just put a fresh piston and rings in it and now it will idle fine, but if you give it past 1/4 throttle it cuts out and backfires and won't hardly run, but it goes right back and idles fine. If you go straight to full throttle it bogs and dies? I've tried plug, reeds, and cleaned the stator. Anyone got any suggestions?

I ran a compression check and it had 85 psi, not sure why, I am using a stock cylinder that I haven't used yet, but it looks good, can't figure out why the low compression, everything looks good.
