  • Why does everyone just mindlessly blip the throttle really fast? Why don't they bring it up to, say, 1300 and 2500 and stuff so that we can get a feel for what it really sounds like on the highway instead of just sounding like a toughguy at a stoplight?

  • Rock, that's a very good question. That was my hand in the video and I was only testing throttle responsiveness to the Bing carb, not RPM range. Unlike the production model, this prototype (John's)had no tachometer so I did not want to unknowingly run it into a range that would have damged the engine. The 1st production model (mine) has the tach info in the mirrors. -Ollie (Afghanpilot)

  • To be honest, I purchased the #1 production bike without riding the prototype. I also changed to a chain drive due to the torque the Rotec 2800 puts out, 7 into 3 pipes for more horsepower, softail for a smoother ride and hidden handlebar cables and reservoirs. Thanks for posting.

  • Batjac you're absolutely correct regarding the vibration. While I was at the JRL facility he placed his cell phone on the fender and it didn't budge. Totally smooth.

  • whats the speed of that thing and how many mpg does it get

  • MPG?

  • Could you not have 5 or 3 block engines for practicality and economy as well as the big 7 and 9 for those with lots of money? You might as well.
