I would go with Nigels idea of getting in touch with the local MZ Cornish section. As most modern bike mechanics don’t have the experience of dealing with older bikes, and the tools required aint silly expensive, and I’m sure if one of the members local to you offer to help they will probably have the required puller for the clutch. the rest of the job is just basic hand tools, so a decent screwdriver, socket and spanner set will be well up to the job. Don’t lose faith. and the best way to learn is to do it. just take photos at ever stage of the strip down. so you have a record of how it was set up and put together. compare that with diagrams in the workshop manual. and take your time, patience is key.
