I was playing around with an extra topend I had when I discovered this. Ok, so here both transfer ports are open on this side of the cylinder (The piston is hanging out of the top the cylinder way past TDC, dont worry about that right now.)

Now in this picture, the piston is near TDC (The piston is just held at the top of the cylinder to keep it from falling out so its not exact) and look how much of the transfer closest to the exhaust is open, and the back one is closed almost half way off. This is off of my 500R. Whats going on here? Is it just because its a Wiseco? Are the stock and Pro-X pistons any better? That has to be hindering a substantial amount of mixture flow. I dont really know the answer to this, I'm looking for suggestions and theories. This isn't a "I know the answer and you guys have to figure it out" thread :cool:
