I recently purchased Treatland's Tomos A3 "Largest Kit in the Lands". It's basically a 45mm A35 cylinder with and specific A3 45mm piston and 10mm wrist pin (which I am upgrading to a needle bearing). I also got a Tecno Boss pipe for it. I'm using a Dellorto SHA 15:15.
My question is, what's a good main jet size to start tuning the carb with?
