    Top end assembled and engine all together! Two stroke noises and blue smoke not too far away now.

    Thanks! Hopefully with the powdercoated finish i can keep it looking pretty decent with a wash and detail after each ride.

    Some more progress, the carb, airbox and intake are all done, pipe repaired, painted and heat baked. The muffler is a sealed unit and was badly dented so have cut a delicate square around the mount to enable it to be panel beated from the inside, then repacked before it is sealed again.

    Beautiful work. Brings back great memories of hurting myself every weekend and trying to hobble back into work on Monday. I had both the explosive RM370 and the more controllable RM400. I could ride the RM400 faster, but the 370 was much more exciting because it let you know that it could flip you over on your back any time it wanted to.

    Well, you have a great dad!

    What is the story on the antique bike in the background of one of the photos?

    Also, I notice he only removed part of the paint on the tanks. Is he planning to blend into the original paint somehow? Always liked those alloy tanked RM's!

    The other bike is a british triumph around 1910-20 era (i'm not sure on exact year) My Dad ran a british motorcycle restoration workshop for quite a while but is now retired and just does some personal small builds at home.

    Both tanks for the RM had to be cut open along the seams, i had two tanks but one had been very badly squashed from the top, and the other had the tunnel forced open wider around 50mm (presumably to be fitted to another model bike) so we had to seperate the tank halves and sort them out, i think Dad is going to do one tank at a time with paint and use the old stickers as a placement guide for the first tank.

    Here's the bike as we got it, you can see the tank damage. Once cut along the seams they were repaired then welded back together. They are incredibly lightweight and we should end up with one really nice tank and one pretty good tank as a spare.

    Tank halves welded back together and pressure tested all ok, they are ready fr etch primer now and will also be getting a clear coat once done to prevent any problems from fuel spillage.
