Ride it,,,,, Hell, I WANT it. I could tell at the DR, you were on the right track with the long tail. You just needed a place to put the feet down lower.
I'm so tempted to build someting much like it. Money is, as always, the barrier for me. Got me thinking though. I have an old 5304, Some 3000 watt controllers, frames laying around, and a welder. Maybe I could rig it up somewhat like a stokemonkey. It wouldn't have that insane power, but maybe enough to at least pull cool wheelies.
You really showed us the way this time. It's a classic bike that goes down in history alongside the bikes Dr Bass has built.
No doubt, you will quarter mile it sometime?
