So far I have ridden 2 skis that are similarly (I use that term loosley) set up compared to mine. One is a 701, 2nd bore, ported, stock carbs, MSD enhancer, swirl, ada head and TNT pipe, it makes more power all around and has better responce, BUT its ported and mine is not.
The second was a fresh 701, ported, B pipe (ported), head, MSD enhancer, 48 carbs, wamiltons built ski, the bottom end (right off throttle) was actually less than my ski but everything above 1/4 throttle had more pull than my setup. I think with some porting and maybe smaller domes this thing will make some great power.
