I go to dunes, live in AZ. Yes I agree it is too lean, but it cuts out and is sending flames out the exhaust once above 3/4 throttle, which would indicate too much fuel because it is still buring it as it comes out the exhaust. I have gone from 150 to 162 with no change. I feel it is something fundemental. It is very consistent and does it at the same RPM. ?????? any thoughts anyone

I bulit a banshee with long rod 4mm stroke approprate spacer plate pro design head pump gas pro design intake with bottle v force reeds over sized pistons 34 mm carbs cpi drag pipes -Cuts out on top. Once you hit a little over 3/4 throttle it is like it hits a rev limiter. It acts very rich. I am at a 150 main and it still does it. It will spit blue flames out. Am I missing something or do I need to go leaner. TORS is off. Help Thanks
