Could it be that you have 350 cylinders on the S1 bottom end? If so, maybe just a port clean up and you are good to go. |

I think it is a custom pipe of a Suxuki 380 they also made one for the Waterbottle. I might make a diferent 3 into 1 a two stage setup with a plenum chamber.And a few extra ports.If it don't work i will scrap it and use another motor.
