Yeh, don't tell him that the rotary valve head won't work and he will probably make a success of it
Looks too good to be true, good on the young guy! Now just to turn it to a Uniflow twostroke.

Becoming a two stroke won't improve things much - I reckon any kind of sliding exhaust valve is severely handicapped from the start because of all the heat, shit and lack of lube.Originally Posted by Flettner

The good old poppet valve still works ok despite all it's failings, which includes cams (thought you'd like that bit).

This is the Excelsior 3, - Thought for a moment it might be an Anzani engine, but can't find Anzani having had any association with Excelsior.
Here it is anyway plus a twin (in a car).

He will be dyno tuning this engine in near future. Oryginał engine had giagantic problem with making power because poor casting quality of the head and the valvetrain components were made of not good quality materials.Right now he doesnt have problems with heat because it's not tuned for any power I think.

Twostroke has a sliding exhaust valve.

Now, I had a bet with myself and anticipated that you'd say exactly that! - In my defence I was going to reply "well, but in that case, there's a nice cooling oily charge coming in right over the sliding component" However, as you said, don't tell them it won't work and they'll probably succeed!
They're using the good old Kiwi "suck it and see" attitude and that will tell them once and for all whether it will work or not!
Polish people are well known for not giving up too!!

While we have ventured onto the topic of pommy 2 stroke twins, it reminded me of an absolutely beautifully styled. Oz made, luxury sedan, powered by, no less than the Villiers 325 cc twin.
Ladies and gentlemen, I offer you the Lightburn Zeta circa 1964.
But wait, there's more! As a result of its overwhelming stunning international sales success, a sports version was also made. However, as a reflection of its sporting character, it was fitted with a 500 c twin.
You've gotta admit, pretty impressive hey.

Noddy and his best friend Big Ears would have really really loved that one - especially the sports model!

Low personal B.M.E.P.
Saw a writeup on the Lightburn saga some years back. The pom who was behind it had been involved in kit cars back in the UK. The Zeta was pretty much all Aussie but the sports was alleged to be off the moulds of one he was involved with in the UK.
Again from memory, at the time of the writeup he was heavily involved in vineyards and winemaking in SA - and doing very well indeed.

You have to admit, it would look real nice with a V6 300 HP twostroke under the bonet, six chambers all stuck out the side!While we have ventured onto the topic of pommy 2 stroke twins, it reminded me of an absolutely beautifully styled.

I am pretty sure Mercury or one of the other outboard makers did a full on V8 as well Flet.

How about using the chambers as an integral part of the body and save space and weight - that would make it a hot little number!
But ...... after having had a good laugh about it, I'm sure that right now it's a valuable collector's item - and it really does have some appeal.

Confirmed, it's in the National Motorcycle Museum at Willenhall, near Birmingham airport in England.
Some more info on it here:

Sammy has some Ariel square fours, and four cylinder Hendersons in his museum.

Thought you were probably right, - would be nice to go over there and soak up the bike stuff but I don't think that I'll be travelling much from now on unfortunately.
Still I did have a lot of bike fun over there and a lot here too.
I spent 22 years in N.Ireland and 50 years in New Zealand! (50th anniversary of my arrival just a couple of days ago) - so I am much more a Kiwi now!
But .... who knows I may still make it!
