Joey: Willing to share/swap port maps? Mine never really throws me off the back ever, just a smooth increase in power up to max revs. I'm geared 16x42 also.
I'm hoping the case induction helps; I sourced a reed block off of a Kawasaki KX80, and I'll make an intake for the Mik. The reeds are the stock metal crap, so I'll replace them with 0.3mm carbon. Or maybe dual-stage Boyesen?
