can anyone tell me if there is a supplier of B40 high comp pistons in the UK ?

the metal removal is a very good idea and worth considering if it proves too problamatic/expensive finding a custom sprocket, thanks

Im just wondering if anyone knew of a sprocket manufactuer who could make a one off rear sprocket that would need to be offset by 10 mm ? . this is because ive aquired a very nice Montesa rear wheel (complete with akront rim) that I want to fit in a BSA C15 frame with a B40 engine, problem being the chain alignment, I would need an offset to move the chain run closer to the tyre. im not sure exactly what model of Montesa the wheel is from but I do still have the original sprocket that came with the wheel, although the ally has delaminated and corroded its still usable for providing sizes etc.

Hello michael, thanks for the info, is that an american company or a british one, do you have an address , all the best buddy, Ricasso
