We are going to do some testing on valve size vs power in a kart engine. The engine is a Tillotson 196 cc shortblock (designed for stocker classes). I will be installing a clone head (from Mike at clone engine parts online), it's set up for a 27mm intake, 25mm exhaust package. I will flow it and then dyno it ...then I will be installing a 32mm intake valve, and only blending the bowl to the seat..reflow and redyno.... let's see what happens.
