Im running the dellorto sha carb with a .65mm jet. Im sure i can tune it better but it runs awesome with my expansion chamber. Im running 93 oct and when i had the factory exhaust wit 93 oct i had more four stroking going on until i added the expansion chamber.

As for the record, i bought a 36t sprocket so it should be in next week. Cant wait to see how this motor does with the new sprocket.
