I just noticed, this hemi is on a bike! Yahoo, hope it has electric start.

I saw a guy with a Boss Hoss, chevy big block. I can get having a small block, but that big block was extreme. I asked him about the torque when accelerating and he said you have to hang on to it. He also stated not to start it by standing next to it verses sitting on it. He found out the hard way when it flopped right over after cranking it.

Looks pretty cool. Keep us posted

I like to think of it as being two wheels mounted on a Hemi.
Hanging on to torque is a problem that is dealt with in the controls. I agree that burping the throttle on something like this needs to be done with care when not moving. At speed, it is much like feeling a side wind and no big deal.
As for kick-starting--Its funny you mentioned that. In the pic you can see my "kick starter". It is from a Honda 90. My intent is that it would trip the electric starting. And with the engine being fuel injected it should come to life with ease.

I'm liking the kick starter idea!

How did you form your tubes to the square ports?
I bought a kit of 45 degree and 90 degree bends to work with . Also a couple of welded doughnuts for the tightest bends.

I had many puzzles to solve to make this workout. And making tools as needed got me to this point.
