4 mill stroker port and polished, lockup clutch, cpi inframe, 33 mm carbs, coolhead 18cc domes, running vp 112. I run a 17 tooth front sprocket and i think a 41 in the rear. I just checked my time sheet and i ran low 8's in the 1/8, but thats with a 17 front sprocket. It should be low 7's with the right setup.
