    I don't know much about 2-strokes but scavenging in 4-strokes is a function of velocity of air. I make my ports smaller (and uniform) to increase velocity which increases scavenging and low-midrange power (at the sacrifice of top end due to the restriction of the smaller ports). The faster I can get the air moving the more of it will fill the cylinder while the piston is doing nothing at the bottom of the stroke. It's supercharging effect similar to an expansion pipe on a 2-stroke.

    I may have gotten lucky... there is another guy here in my area selling an identical four wheeler for a few hundred bucks. The one he has was stolen but recovered and the thief took carb and battery off of it. If it is still there next weekend when I get home, I will be picking it up. He says it was running next year.. if so I may just slap my good parts on it and then decide rather to just slowly rebuild the current bike or just keep it around for a parts bike. Figuring out what is going on in the transmission is more than a little worrisome to me.
