They are crude, piston ported two strokes, hot rodding them like they did in the 50's applies.

Well, A good plug wire help the chinbna engines a lot, and so does opening up the intake/cleaning the ports up, as long as you adjust the mixture accordingly.

They don't have a flywheel to be lightened so to speak, and I don't have an knowledge of the stalker exhaust, so I can't comment on that.

I will say these engines respond to all the regular basic hot rodding tricks.

Reliability goes down as power goes up.

So.... dealing with a numb skull like me, I'm cleaning up the intake manifold that I have, HOW or what setting would I want to put the clip at?

how are you cleaning up the intake manifold. I've read that the interior should remain alittle rough for atomization.

On the steel manifold I have, the weld was about 1/8" off. So I'm cleaning that up. If you stuck your finger in, the one side you could feel the metal protruding I've just ground that off. I have the older style cast manifold on the bike currently. I hope that makes sense.

Cleaning up the intake will not likely need a clip adjustment unless accompanied by an mod to the air filter cover.

You may see slightly higher revs, or a little better pull in the mid to upper end of the rpm range.
