I totally agree. And it's not as if once built, your trying to kick over some little triumph 650 engine. These are big motors and take some oomph to crank over, let alone kick. There's not a whole lot of timing or carb jetting information out there for them which make s huge difference on starting an engine, especially a kick start.. I saw a good running super vee at the Minnesota Isle of Man race a couple of summers ago. The guy was using the Super Vee bike to trailer his cafe racer to the event. He said he had over 60,000 miles on it. It was one of the last generations ones without the exposed flywheel. He told me he had one other one as well.
On a similar note, I know of one other engine where a guy cut the front 2 cylinders off a Ford V-8 and had it running so he could eventually put it in a bike. But he never did. He was my brother in Law and I think he still has the engine. The Super Vee was a good idea but the quality control was pretty crappy. But they can be made to run.
