Now Ian, that's something to ponder, which engine to transplant into a New AJS?
Electric start Serow springs to mind, but it seems a shame to spoil a Serow, any other suggestions for a suitable donor engine?
I have a couple of spare CB250 RS lumps, in truth they are a bit too big and heavy, I once offered one up to an XL185 whilst I had it's engine out, just would not go in without extending the frame.
Robin.
