Here is the lubrication chart for the Montesa 200, use 2 stroke oil mixed with the petrol maybe 50:1 ratio, so 100ml of oil to 5 litres of petrol, it looks a great project to restore

@rustyrider you’re the man ! Thank you very much they’re the specifics informations I was looking for !

I’ll let you know about the restauration, My next step will be removing the tank and air filter then 😉

The changes was I bought a later model Montesa 309 frame, swing arm and yokes, and converted it into a twinshock instead of an air cooled mono frame, I done this by welding the rear subframe to the main frame adding strengthen gussets where needed and top rear shock mounts on the frame and swingarm, the 200 engine fits straight into the engine mounts with no modifications, I used the original wheels and front suspension, the only modification was new front wheel spacers and I fabricated a new front mudguard bracket as the 309 yokes are wider than the 200.

Once the bike was in this stage I then bought a Montesa 310 front exhaust pipe and modified it to connect to the original 200 silencer, I fitted a dellorto carburettor from a Montesa 315 and fabricated a alloy air filter box and used a Montesa 315 air filter, I made a alloy chainguard and bought a Montesa 307 seat/tank unit and welded bracket to the frame to mount it, the seat I made to.
