Cm200 cheap fixing up

I had some different bikes in the past, the most Jawa 350s in different versions, and for short periods some bigger more sophisticated bikes.
I kinda wished for some very basic bike, preferably 2 stroke, 1 cylinder, not too big, also not too tall (I'm short, damn it.).
I was actually without bike having only an old Jawa scooter purely for tinkering, when a colleague told me, that there's some "shiny" bike in storage left by her Brother. Had no idea what it was, only that it had to go ans they got fed up paying taxes for the vehicle.
Took a look, smiled, paid.

Soon I had the plan... I like simple bikes, right? This is pretty simple. Lot of moving parts, compared to a 2 stroker, sure, but hell. It was dirt cheap. (I guess I paid 200PLN, some 70USD...??)
I will have the original seat thrown off, make it a bit (just a bit) like a dirtbike of the 70-ies.


Bike came partially disassembled, but almost complete.





Some aftermarket indicators and taillight:

In some days to come I figured out and fixed a few small issues, like fixed up the taillight, indicators, got a battery, plugs cleaned carb, and replaced oil. This did not look good:



Learned that, the starter clutch does not work, so hoping, that the metal rubbish on the filter came from the clutch. There was a home-made spring for the oil pressure valve which I managed to replace with an original Honda part. Removed the starter motor relay just to make sure... Compression test came up with promising results, about 122 and 126 PSi

Afterwards there was a lot of trouble with the carb. At the end I just replaced it with a locally available Chinese copy. (sold for some of the bigger quad engines) With new Denso plugs the bike started up and finally had a stable and adjustable idle.


quickly put a plank on it as the seat, mounted the mirrors and took it for a ride.

I'm not usually a forum nazi, in fact I have a CM450 myself and I love it, but you are posting this build on a BMW Airhead thread.

Here we are right now,





I think there is a pair of MZ shocks, which seem to be longer than the original. (DDR is stamped on them (East Germany).
right cylinder smokes, so I guess after a while I'll have to pull off the head and sleeves. :/ But it pulls ok, has a badass noise as 1 muffler has a hole in it, and apart from the weird sitting position, it feels ok.

there are two new tires in the back of the car now, I shall fix a licence plate holder and get it registered. ;)
