I think I am topping out about 25mph,but the torque feels anemic,the slightest hill slows it down.
I only have about 10 miles on break in so far,need to find some flat lander ground to run it with out having to lug the engine trying to go up and down hills.
I did check the head bolts today and they were loose,so I might have been losing some compression,will run it tomorrow when the rain ends.
Did modify the air breather some with my drill,still waiting on a jet kit to see if I can get some more torque out of it.
