we had dadders experiment on that one as we werent planning on using it .We have another but didnt have time to get it broken in for the race. So we went with the old one. Dadders can modify your to be like ours but it does burn a ton more fuel as he did something to the transfer ports.
We use a starter box as we dont want to rely on a pullstart for racing.
contact dadders for info about his port work. He can probably tell you more about what he is able to do for this motor.
