Scotto,
Yeah I've priced them & they are silly priced (over 1K).
I may go with fatter tires (possibly knobs) but for right now its good to go.
I finished up the floor board this morning & ordered some new ACS Crossfire freewheels.
After having experimented with two different ranges of gearing (front different than rear), I decided to make both geared for 40 mph & run both engine throttles all the time.
Having them geared a little tall for high speed will still give real good acceleration since two engines are pulling the load.
So far the ride has been great with no mechanical issues whatsoever.
Like riding on a magic carpet only standing...lol
