Hello,
I have a 1944 WM20 that I am trying to keep going. It seems like the previous owner didn’t focus on tightening the nuts and bolts that holds the bike together. Assuming the bolts that mounts the engine to the frame are the original ones, what nuts do I need for them? It would be great if someone knew size and type of threads for these…

Cheers,
Tom

Tom the engine plate studs are 3/8" BSC. But there is lots of further information on the technical page of this site. Ron
