Test Partners gezocht:
Wie rijdt er met een 24mm carburateur en heeft tijd en zin in het samen afstellen en testen van deze nieuwe carburateur van XTNG?
Er zijn een paar prototypes gemaakt van de nieuwe serie 24mm-30mm en de 24mm komt naar mij toe om te beoordelen.
Straat, cross, race, allemaal prima. Laat maar wat horen. (Het is wel handig als je een beetje in de regio woont)

Solutions to problems.
This engine had an 60 years old unreliable and tired ignition with odd sizes. Nothing would fit the easy way. So I decided to work with a PVL internal rotor unit and a steel spacer plate that gives some wanted flywheel effect.
It was a challenge, but it fits and works.
The engine is very lively without being nervous.
Its a moped with mild tuning, doing a bit over 60km/h instead of the boring 40km/h.
Light? No a PVL has no light. Plan is to use LED lamps and a little lipo battery. 8Ah, one charge might be enough for the whole season.

Riga engine part two.
It didn't shift...it refused to shift..it locked somewhere half between the gears.
And its probably made for big Russian boots, the shifting action itself takes plenty of force, hard to do by hand. Which makes the search for the problem harder.
But I think I found the mistake, a mistake that is typical for these kind of very rare engines, which are in fact hand made piece by piece from a drawing. (I had exactly the same problem when I was rebuilding my Tatran racing engine)
The mistake is: parts from another similar engine.
After first examining the gearbox parts for unusual wear patterns or damages, which it didn't have, I finally found out it was impossible to slide an engaged gearwheel off the axle.
This should be possible.
Then I noticed the gears are actually new, never used, new old stock parts I guess.
But...the cutouts in the gearwheels for the balls are not deep enough (maybe 1/10mm) to combine with this blocking rod.
In the rare occasions it engaged a gear the whole thing then got stuck and needed brutal force to disengage again.
So I adjusted a few cutouts and the shape of the blocking rod.
Now it seems to work. Hurra 🥳

Today something very rare..
Its a 50cc sport engine produced in small numbers by the Serpuchov Institute near Moscow in the USSR times.
Mostly used in little offroad/motocross bikes.
But this one ended up in a Riga racing bike.
Type 6s, made in small(5?) numbers.
It needs overhaul and won't shift.
So I am digging through the engine an wondering about the shifting mechanism that is very ingenious with its rotating rod to block the shifter balls.
But the parts also show the mistake in this, the ball always wears on the same spot on a very slim ridge.
I just hope after a bit dressing there is some life left as I want the bike to ride again on special occasions.
Most people (me too) are intrigued by the weird inlet and outlet same side arrangement.
Things look smart enough inside. Its clear they came to this arrangement to make a big 3th scavenge port in the back.
It flows through a big hole in the piston.
