Turns out it was my own fault. For one I should have fully broken in the motor before today and got a good race tune on it. But it was a busy week. So I went back out on the track after all the mains were over to try again. I started by pinch testing the low-end, ended up being WAY to lean. So I fattened it up about 3 or 4 hours.

Started driving it and it was fat through out the entire range.. So I thought, 'hmm, lets try leaning out the top.' I ended up leaning out the top about 4 hours and that really seemed to wake it up. I had essentially been tuning it backwards. Once I got it right the thing was a BEAST!!

It ran cooler and just performed better from bottom to top. I guess on these race engines the LSN controls a LOT. Wasn't like that on my Go 3 port. I think I mostly have it running good now, temps were about 260-270 with no idle issues or flame-outs.

p.s. I have the new shorter LSN.
