I put on a hub adapter and 40T with 26x 195 tire gps it at 39mph on flat ground. I normally run around 20 riding around. I do have a CDI question, there is a lot of info on this subject. But some old maybe some not true. Does the stock CDI advance the timing to much? Will it beat the bearings out? I have the BBR stage 1 CDI. I think it’s stock with a NGK wire and boot.
