4 Mil Stroked Stock Cylinder Setup v/s 4 Mil Cub Setup


Recommended Posts

Had a stock cyl 4mill dune port by fast. Ran pretty strong. Had the crank bearings replaced and re welded after 6 years just because I was doing a new build. Just built a ported serval by fast. Id say both motors were between 70 and 80 hp.

 

 

I had been looking at either fast or hjr. Fast is closer, and shipping would be cheaper but hjr has kits at a decent price.
