I wanted to do the same conversion to my 348, since I like the idea of the alloy tank safely fixed under the flimsey GRP cover. I was told by a bloke that had a set to sell that they dont fit since the frame is a different size.
to repack my old montesa cota (1978) do I have to cut the chamber open?
since it doesn't have a fancy unscrew able end plate. It is simply a welded up metal can.
Would it then be worth bolting the hole shut so in future I can repack it without needing a welding torch?
