With a vacation ahead i was happy to finally get a full working day on the bike. I had all the parts for building up the frame sorted cleaned,serviced and ready to mount (linkage, swingarm, brakes, suspension).
Grey airboxes are not easy to get, i found this one in a nice condition. Cleaned it and applied a thin layer of matt clear coat, this way it looks like a almost new airbox!
I went on steam with a verry long working day
Tried some things to restore the fuel tank. After this i found 91 technosel fuel tank stickers for the fuel tank.

For now i want to try the 36mm PJ carb wich i rebuild. I have a 38 also, that one i ordered a service kit for. I have a CR250 intake tube fitted, already for the bigger carb (wich i think will work the best). I like the oem colored keihin carb vent tubes
The exhaust damper is one from the brand hgs (also dutch), it needed a refill, so i got that one fixed and got the steel parts whire wheeled so they look like new. New stainless steel gastight rivets.
The exhaust pipe i found from the italian brand Messico turned out to be a type that you don't see very often. Is has more sections than the normal production one, maybe it is a older version? Still trying to find out. Would be cool if someone know annything about this type.
I also had a exhaust pipe calculated and build, this should be a more top end pipe so we will see! A custom made coned exhaust pipe always looks good in my opinion
Frame vin sticker remade
Twin air oldskool stickers
Hrc style case saver
The benefit of this part is that the area from the case saver that contacts the crankcase is a lot bigger.
My favorite: a exhaust joint that has several o-rings to seal the exhaust flange. The stock construction leaks verry fast, and i doubt if it ever seals 100%.
It comes from a kart engine industry company, nice quality stuff! It also has o-ring mounting at the back where the flange meets the cylinder.
When i bought the bike it did ran healthy, but now that everything is new the sound of the bike is like a new one! Bike runs healthy with a fast throttle response.

Excellent job it looks fantastic.
I’ve tested almost everything i had laying around for the bike.
Some dyno work: Honda CR 125 dyno
I started out with 33-34 hp (this was with using a stock pipe+vforce and 36mm carb) and for now i have it at 37.1hp with a (38mm carb+govener mod)
That’s only 2hp less then a stock Husqvarna TC125 2017/2018 on our dyno. Real two stroke fans know those bikes are fast.
After all, it has to be proven on the track also. At my first race i got an insane good start with my 125 between the combinated class with 250s/500s.
Will post dyno charts soon!
Nino is the man when it comes to the hpp. Someone needs to reproduce the 99 power valve and guides, as theyre getting rare.
Can you get leaded fuel in Europe?
Honestly i think a 125cc will give you more rpm's than a 139 kit. I have tried a 139 before, i didn't like it over a 125.
I talked and still talk with Nino about engine performance and things to try out. We have leaded fuel here, but only Avgas 115. I'm using RON102 fuel for the bike.
I will use 100 avgas for lead but end of year lead is banned in Australia. Is your 102 fuel oxygenated much?
