Interesting thoughts. We got the 2 bikes. Because they could not be registered in California IA due to smog, but the are a great donor for the parade Rat Tryke. To project uses the engine trans and a 85 MR 2 trans axle. So it is gear low for parades and has a reverse. I have a parade for it Sept 21 so I am getting down to the wire. One other problem I have is actually finding a wiring diagram that fits the harness. So I am step by step testing out connections. Thank you for your input.
