This was touched upon in the budget bikes thread, but I'm going to start looking for engines now and was wondering what opinions were on the BSA engines (or other brands) that are pre65 legal. The frame I've got is a B40, and after reading a couple of magazine articles I'm thinking a 350 would be the go.
I suppose the main aspects I'd be considering would be availability, cost, reliability and the like. Nothing too obscure just for the sake of impressing someone else, just something that'll go well, look good, and not bankrupt me.
The B44 350 was mentioned in the budget bikes thread, is this pre65 legal?
Cheers
