I started playing the game again after a 2 year break I took from it.

These are my new creations:

- MÁV Class V44-001 "Radony" Electric Locomotive https://steamcommunity.com/sharedfiles/filedetails/?id=3814291052

- MÁV Class MDmot diesel multiple unit with a working control car https://steamcommunity.com/sharedfiles/filedetails/?id=3810463157

- Ganz-MÁVAG Type VM15 prototype based on an old blueprint (This was the first thing that I built after starting again) https://steamcommunity.com/sharedfiles/filedetails/?id=3802315690

So I've managed to get my hands on one of these things. They are very rare and so are the parts for it. It is practically equipped with a Morini M101 but with some twists and redesigns that make 80% of Morini parts incompatible with this. It started on the first kick after a carb clean, but it was producing the symptoms of leaky oil seals. So I disassembled the variator side and surprise surprise... the crankshaft is loose on the bearing.

Great, time to pop the cases. I've managed to get new bearings and new oil seals, and got to assembling the engine. I've glued on the variator side bearing with CX80 RC38 bearing retainter.

But if I've disassembled everything, why not do some tuning? So I've machined 1,7mms off the cylinder's top to get those 5 sweet channels to open up fully, made a thicker base gasket and started working on a 15mm intake for an Arbeo SHA 15.15 carby.

And by pure luck, I've found a CDI that has no speed limiter in it for dirt cheap. I've tested it on my regular Eko with the Indian clone M48 engine and it works great.

I have high hopes for this project because this thing went 48 km/h with the restrictions (my regular Eko goes 46, tuned {goes 30-35 stock}). Hell, this thing might go 65+ km/h if done right. I am assembling the engine fully tomorrow and will do the first start after the maintenance work.

The shifter mechanism pushes over the detent of second to neutral when I'm dowshifting from third. This is a 50cc semi auto engine (KN139FMA).

I know this isn't a pitbike, however the engine is from one. This is a 139FMA 50cc engine with a PZ20 carburetor. I've installed a vacuum fuel pump because the petcock sits below the carburetor. I tested for air leaks a dozen times, even used some sealing paste on the gaskets and it still seems to be surging. The idle screw is almost backed all the way out, the air screw is 2¼ turns out. The pilot jet is 43 and the main is 72. Even if the slide is all the way down this thing still idles (yes the cable has slack so that doesn't hold it up). Any ideas?
