Have you tried these guys yet? https://clasicaslegendarias.com/ Have a look and compare the part numbers of the Cota models listed.

The film has to be 'thin' in order to fit smoothly to the curves of the panels. Hair dryer helps in keeping it pliable. Using soapy water is normal for applying self adhesive graphics. It is 'thin' sticker with adhesive on the back.

Cheaper vinyl will not be as durable as some of the more expensive types. The surface that you are fixing onto MUST be ABSOLUTELY clean. Wash, wash wash, then wipe down with IPA. You will need : A trigger spray bottle with soapy water. Spray the surface with this. Helps slide the film into the exact position. A hair dryer to help the film stay as flexible as possible in cartain positions A squeegee - old credit card A good eye for lining the film up An absorbent cloth to mop up. Once in position, leave fro 24 hours or so for full drying and adhesive bonding.

I think that the cover you describe will fit the earlier 247 models. My 1982 248 looks like this on the drive side

348cc

Engine through bolts are M7 (as are all the engine outer casings). I did not torque mine up. Just used flat washer, spring washer, drop of thread lock. You might have to resprt to the Dremel method to remove the bearing race out - 3 or 4 surgical cuts....

Very common problem. That lug on the kickstart shaft always causes this damage if rotated too far round. Seen it lots of time, and search posts on here for other pictures etc. Will need proper welding - preparation is key. If the case is oily welding will be difficult. Casting will need thorough degreasing. So, engine out, head and barrel off, split crankcases etc, etc. Otherwise the timing case will fill with water, mud, oil etc and spoil the Electrex electronic ignition that somebody (you?) have fitted.

Try Vallmoto in Valencia, Spain. I bought most of my 248 parts from them.

Hey. Nice collection of bins. Really though, bike looks like its had very little use?

Pressurize with a high pressure, low volume hand pump as used on MTB forks and some MTB shocks.

Also heard that kickstart gears are 'a known problem'. I was looking to buy this bike, but I'm cooling off a little....😐

Last on here a lot when building a 248. Now that has gone, I am looking at a MH200, year 1983. (According to the VMCC dating cert for the V5). So, one key question. It has a plastic tank under the cover. What is the current position with modern, ethanol fuel with the plastic. Do you need to use a 'special' additive in the fuel? Does the tank have to be lined? Is there an alloy fuel tank from another Montesa that fits as a replacement?

This is a very good source for carburettor information and spare parts. https://surreycycles.com/

Best to ask them.
