One thing that the Ryger did do was to get people thinking outside the square for a bit, possibly leading to some quantum leap in performance as the Ryger was purported to do. Alas, neither came thru.
The other thing that gave us the shits was the way one of our key 2 stroke posters here on ESE (and elsewhere) was badly compromised by the first stage of the Ryger story
"Success is the ability to go from one failure to another with no loss of enthusiasm.”
There was a bloke racing a Bantam at a Belgian meeting a few years back who had a small oil cooler/rad mounted to one side of the frame downtube even though the bike was plainly air-cooled.
Turned out he had an electric pump circulating water through copper pipe in the primary chaincase to "give the clutch a chance of coping with the awesome power"
When I lived in Belgium (up to 4 years ago) there was a house nearby that had a collection of 2 stroke cars and vans parked around it, mostly pretty sorry looking examples, sadly.
If you search "Grensstraat 10, 3078 Kortenberg, Belgium" on Google Street View you can see that some of them at least were still there when the Google camera car went past.
After a long time a small update.
First of all, see the new factory that is also a big improvement.
The engines have been reliable and ready for sale for several months.
At the moment enough people who are still very enthusiastic and have also bought an engine, and I'm sure they would not have been if the power was only 35hp.
Their enthusiasm was most intensified after making a test drive, which can take place almost every day by appointment.
The sold engines will certainly participate in competitions this year.
I can't edit my previous post so again with an better link

I went to an experimental electric vehicle get together tonight where people talked about their latest projects and all things EV that they were up to.
And by chance I saw this portable go kart dyno that they make here. A very clever piece of kit. Not only the normal dyno functions like rolling road simulation and direct axle coupling it could mimic a track and put the cart through the same demands as if it was racing by simulating the track. Not only can you use this dyno for tuning at the track on race day. By using the computer control system to simulate a circuit you can use the dyno anytime to tune pipe ignition etc for the best lap time and base setup for any particular track.

Very interesting motor. I love the position of the fuel injector, I wish I could get mine so directly under the piston so it can squirt onto the under side of the piston crown to cool it.
Certainly old news here, but think it was entertaining reading about a mechanical push rod injection
first I thought it was united flow design but it just seems to be exhaust

No amount of experimentation can ever prove me right; a single experiment can prove me wrong.
Are you tried it, or still in process. On Experimental Aircraft Association forum I saw one, maybe, earlier version (posted photo some time ago )
Last year I prepared for the tests two different pistons, different from previous tested versions, but at the end one looks too fragile, another too heavy, so nothing was tested. Like always, never know what happens tomorrow. Best luck for your projects.
Another two inventions with separated crankcase. Christian Vialette called it Three-stroke.
