I should have asked this before...did you do any work to the crankcase? There are some gains to be had by cleaning up the inside of the crankcase and helping the fuel\air flow through to the transfer ports. There is quite a bit of material in the way at the bottom of the cylinder right over the bearing. It can be removed adn smoothed out to aid int he flow. Basically get rid of any hard corners and polish it up. I have also found that the ports on the sleeve don't match up perfectly with the cylinder so if you can match them you will get better air\fuel flow into the sleeve.
