The bar you took off the front was short on the ends, It was for folding foot pegs. The pegs you have will hit the ground when you turn. the gearing on the jackshaft you might want to put the larger one driveing the wheel, and the smaller one from the clutch. that will give you the speed you want. You have plenty of power. the bearings :chinese: may have to be up-graded, and you will need raceing chain, not cheap chain.
