Hi Vintagetz,
I will enjoy to read about your builds.
But which TZ125 tank will you use on a RD250/400 frame?
Regards Uwe

Some other countries got an RS125 and a RS200

The RS200 was a 2 cylinder. In fact a low key RD200.
We had the RS100 in Germany also but very few were sol here also. Our RS100 models overhere had a disc brake at the front. But overall spoken it is a boring bike. It was more intended as a low key bike for the asian markets.
A couple of years ago I owned one exactly like the one in the pic.

Finally the bike arrived from the UK here in Germany.
It is really an amazing little gem. In the meantime I got all infos and records of the bike. It is not a 250 as expected. Only the crankcase and the transmission is of a 1986 YZ250. Homemade crank with shorter troke. Homemade cylinder with less bore. So the displacement is down to 200cm. That was done to can parcitipate in different classes in the UK back in period. They had a big 200cm class scene and a few different 2stroke single cylinder classes up to 250ccm. Got spares of the homemade casted engine parts with the bike. And the bike has a name also. It is called Tomic 200. Created by the name tags of the 2 builders. Very pleased with the bike.

Hi,
the RD400 has a different diameter compared to the early ones. At least the european models. But we have Hitachi units. So not sure if that will help
Regards Uwe

Thanks @1976RD400C and @SoCal250
That will help. The YR1-3 range is very rare overhere. I doubt that more than 2 dozen bikes are on the road
Regards Uwe

Hi all,
a guy on a german Facebook site has bought a YR3 and is a bit struggling to find data for that bike. Very rare bike overhere.
How much gearbox oil to fill in that engine please?
Regards Uwe

Mark,
the frame was the reason that I wanted hat bike. I always desired a monocoque frame, equal which 2stroke engine in it. Such a unique engine which is in it is a benefit for me. I have now a monocoqued framed race bike, a trellis framed(Siroko TZ) and a central tube framed(Höpfner TD3) one, beside the normal framed bikes. I have the patterns and drawings of the Scitsu frame also lying here. For a bike like that one:

Just haggling with my son in law(who has to build the frame/bike) which engine we will use. 50ccm or 125ccm
Regards Uwe

Hi Mark,
nothing of that bike on Facebook. The guy who built that bike isn't on Facebook.
It was pure luck that my friend stumbled over it last year and that he knew the builder/owner since centuries. "Thanks" to Covid, who let the guy find the time to finish it, it was begun many moons ago and than abadoned. Beside a few test runs the bike is virtually new even the build was started nearly 30 years ago.
As soon as it at my home I will take detail pic but that will be in October, just talked with my friend when he comes over
Regards Uwe

Amazing and beautiful! Please tell us what it's like to ride

As the bike is still in the UK I can't say when it will be here in Germany. Have to wait till my friend attend at one of our races. Everything not so easy since the Brexit.
Above I only wrote what my friend saw at the trackday. He was impressed with the speed.
With a bit luck the bike will be out at one of our meetings in September.
Regards Uwe

Hi guys,
a friend of mine in the UK stumbled over a very unique bike in spring 2021. A friend of him built and developed it. It was up for sale as soon as everything will be 100%. My friend got first option to buy it for me till all is sorted. Well this worked out now last weekend. Everything is running as it should. Very fast bike and handles really well.
An all homemade monocoque frame, 6-speed YZ250 engine converted to disc-valve induction, self engineered and then casted cylinder, Astralite 18" wheels, 35mm fork, Lockheed brakes, tank and plastics homemade also. Many hours in head scratching in this bike.I am very pleased my friend found this for me.

In Japan the RD's were sold as RX350 back then.
Regards Uwe

the NC DMV has no idea thats even a thing, trust me on this one..  . They think Pennsylvania is an exotic land far far away. My bet is its a typo. 

For sure I trust you on this subject Mark. Wanted only to state that a RX350 exist. I have no clue also how the frame numbers begin on a RX frame.

Whoever you end up buying the Vape from, make sure you take all the screws out and blue locktite everything including the small ones for the pickup.

Very good statement. Coming loose screws happened to a friend of mine with his HPI one at a race 3 weeks ago. Luckily RD's and TZ's are common in our paddock so a spare ignition was found quickly. Otherwise his weekend had been over. We more experienced guys had simply forgot to tell him that in front

@teazer
The reason Motoplat and Femsa built everything in house had simple political reasons. Back then under the Franco regime spanish companies had to pay high customs if they bought goods from outer spain or/and some goods/parts were not allowed to be imported at all. That was to protect the spanish industry.
@m in sc
Yes Mark, but HPI buys most electronical parts from outside. HPI is mainly a 1 man band on top.
Regards Uwe

@jradnich
I think you mis-match something. Vape(czech company) and HPI(belgian company) are very different companies and Vape were never sold as HPI ignitions. Vape is the same like the former Powerdynamo(german company) ignitions. Vape was the producer of the electronic components of the Powerdynamo ones. Powerdynamo itself "only" machined the mounting hardware and confectionated the ignitions for the various models. As they closed and moved into other business fields Vape took over the whole process.
