New SUPER PK 80 build

[Stoneman]

No idea what I’m doing but I’m doing it

Any advise is appreciated

That's what these engines are for, experimentation! Don't think those wrist pin bushings will work too good as cylinder head though

looking forward to hearing your results. Anything with a Akubra on the side cover has gota be fast. I don't know if this setup is any better than what you have done, but no harm in showing a pic.View media item 60553

I’ve been told I may loose bottom end with doing that, but I see it so often.

So I figured to start with the very basic than add and see what the improvement is

Bit of myth busting for my self I thought.

Can you use an extension on a reed valve and would there be any effect?

I have asked this and been told yes, it's the same as when you extend the intake on a piston ported engine (Jaguar). But I have not tried it myself yet.

Cool, that makes things a little easier

There is a good chance I won’t have to muck around to much fitting it in the frame looking tonight, but I bet that will change haha

Bit more work with match porting the reed

Looks good.

Any plans for the petals?
