Elwood was a man of many talents (this included being a flag marshal) - but not many realized he was actually a talent spy for Suzuki (on the lookout for budding motorcycle engineers!).- but he was out of luck on that occasion, cos I wasn't present!

Will, that pic is a perfect period microcosm. So much is familiar even though I never got to Baypark in the period.
The tank shape is familiar - seen it many times but can't remember who made them. The tacho is the only one available in NZ at the time which would go over 10 grand. they're a pos. Mine is somewhere here still reading 1500rpm....
The crowd so close. Normal then. Sidecar Bob could probably put names to some of them too.
The back brake operating arm is impressive. No lack of leverage there, lol.
Glad to see that pic, I was beginning to think that all these memories were just a figment of my imagination and I thought, 'gone forever'!
I have never seen that pic before ........ unfortunately I was too engrossed with the bikes to ever think about taking photos myself!.
As you more or less said, it was a rare find and should be treasured - not just for the bike (which was built from parts we had lying around and was just for a bit of fun), but the whole sixties/seventies NZ scene.
If the guy who was riding it is still around, (he'd be over 80 now), he would no doubt be very pleased to see that photo!
Maybe we shouldn't discuss the brake linkage! (perhaps we figured it might be needed when the brake drum at the front faded! ) - I really don't know if there was any theory behind it at all - a mystery!

Chinese Foxtech design not the state of art, just working and increasing range in 4+ times related pure electric. I saw other 2-stroke UAV 11kw 180cc engine which use direct injection and have rather impressive 280gm/kWhr and multifuels. It use air injection system originated from 50cc italian scooters.
JB, from your description it sounds like the Orbital 2 fluid system. 280 gm/kWhr is good. If you have a look at this, you'll see that Orbital till makes engines, specifically for drones: https://orbitaluav.com/propulsion-solutions/. I thought that they were only 50 cc units, but they may have increased the capacity to the 180 cc to cater for larger drones.
One of the key selling features is that it can run spark ignited on heavy fuels, eg Jet Fuel A due to the very good atomization due to the compressed air being a propellant for the fuel charge. Jet Fuel A is a requirement set by the US military so that the majority of all their transport (sea, air and land) can run on the same fuel, this being for logistical reasons.
Might sniff around to see what engine capacities they are working with.

Hi Stefan,
In fact I know nothing about Ryger group, except what has been published in various forms on the internet. So I can’t say anything further about their work.
I still think that stepped piston concept is the simplest of all possible options to separate crankcase and use the fuel without oil. And no additional moving element.
Another question is how to take advantage of the stepped piston for scavenging.
I nearly started again with stepped piston on NSR 250 crankcase, but decide to continue my tests with direct to transfers scheme, with inside reed valve.
This time with 54 mm stroke and Honda RS gp cylinders, adapted to Honda NS 400 crankcase.
Seems like at least one has been located, I doubt they ever sold many at all
