That's the bottom of the Cylinder Larry........I don't see any Aux ex ports (but I might have that wrong)
I only see one and a lot of transfers

The picture is not real clear but could swear I see auxiliary ex ports also. Just as suprising is a lack of evidence that any valves exist in the "valve plate"......... Kermit Buller

Is it an aux exhaust port , or a port to tap off exhaust for reuse/hcci purpose as it seems to be above the bridged exhaust port

**Yow Ling** · 20th January 2016, 17:05

Frits, is this the homologation engine or an early development engine ? are they the same ?

**ken seeber** · 20th January 2016, 17:30

Clearly we are looking at parts that don't necessarily all come from or go into the same engine.
I think the auxiliary ports either side of the main exh port aren't exhaust ports (the doccos we have seen indicate one exh port only), but some form of blowdown ports. There is lots of energy in the exhaust to do something with. Remember the 30:30:30 rule. There could be 60 hp (45kW)or so to provide some charging function as an alternative to using a tuned pipe, or possibly both together. I reckon a 60 hp supercharger (not that it is) would have to be very useful in increasing the power of a 125.
The Ryger could be the way to harness it.
OK Frits, we're thankful for the first feed of breadcrumbs, and they tasted good, so looking forward to the next snack.

The port that comes down from the reed cavity to the base gasket surface appears to almost dead end at the base plate. The open area cross section would only be the thickness of the base gasket.
Clever how the cylinder pilots on the base plate to ensure concentricity.

Ok, I will calm down and not get angry.
The point I was making was we could beat the best in the world, if you raced Biland in his LCR Krauser what do you think would happen after 20 laps
around Taupo - wet or dry.
And I dont want or need the " business ",I post on here to pass on 2T knowledge very few people have.

We appreciate that Wobbly, the more we learn the more we realise how little we know, thanks.

I would get my arse kicked like most of the people on the planet would be.

But boy would I send him packing with his head between his legs in a game of table tennis...

I think it could be an early development engine, the front studs look longer than required. However regarding the ports, the homologation document will include a drawing showing position of these.

and about a cm to the left of the yellow circle looks to be the other end of the duct you mention.

So, a heavy but solid topped looking piston. That fits in a tube for linear motion. A ridiculous amount of inlet area. Conventional transfer area but with sharp holes on the inners.
My brain hurts.
