That guy wanted to run cpi's on the trails, he would never even really see the peak rpm on that pipe in the tight stuff. He never gave up his carb size either.
Oregons drag hills are about 100 yards long and whooped out. The midrange power works nice for the chops the engine does over the whoops. In that drag race video I posted, the front bike is a 4mill 2 into 1 setup with low-mid ptr's. Second place by 3 lengths back was a full port 350 with cpi's and 2 35mm pwk's. I was in third by only 1.5 lengths behind the ported 350 bike with my 2 into 1 pipe, 2 into 1 carb with 35mm pwk, a pro design head, and carbon tech reeds (stock internals). So, yeah I would say the midrange setup works pretty well. I can run the holes, then hit the hills without any issues.
If I ever do another drag bike I am gonna do a cheetah 12 mill with a 65mm electronic tune port injection throttle body on a 2 into 1 intake with methanol and show you all. :yelrotflmao:
