World beating super shit hot two stroke fuel injection is old hat now. This could be Team ESE's next Side Car project.

thats 90cc each cylinder me thinks. they got me another time.

Then we'd better provide you with some more pictures of the beast.

And some more.

hey frits in that first photo is that what wobbly keeps refering as wasted studs?

Looks like it, doesn't it? But in Wobbly's case (pictures below) they really are studs, holding the cylinders and the heads down.
In the Maxiscoot cylinder they are merely filler bars, hanging from the head cover; they have no connecting function.

I thought the maxiscoot ones locked into underside od the bottom allen bolt "studs" and then hold the head on,
If not is there only reason for being to provide access for the to closely spaced 50cc stud pattern?
If thats the case why attach them to the head a all?

They provide access to the studs and they fill the space above those studs in order to create decent flow paths for the auxiliary exhaust ducts and the B-transfers.

Where else? You can't just screw them into the cylinder; they need to be held in a fixed position. The small pins indicated by the arrows are taking care of that.

Frits, looks like a neat bit of intersitial engineering (ie filling the gaps).

Now the reed block manifolds. Are these nylon of some sort and were they moulded, 3D printed or machined from solid?

[Larry Wiechman]

I just noticed the keyslots in the casting.

I'm going to guess that the patent holder, Michael Burgard, is a moldmaker by trade.

I am so sick of our Sla 3D printer. Bane of my life.

Ok. . . Not as bad as the accountant.

They're 3D-printed. I don't remember the type of material.

Guess again, Larry. Burgy is a two-stroke developer by trade; has been all his life.

Who says they need to be fixed???

That was me, wasn't it? Are you thinking of doubling their function and rotate them like throttle valves, Shnaggs? Good idea
