Re: M21 needs more power -any advise (if my subject not is relevant - please remove
Thanks for the illustration, nice looking design. In my opinion it was acually not a bad idea to offer OHV conversion kits most sidevale WD motorcycles. However - since its the first time i hear about Gruppo Velox it must be very rare, and due to that - not a big sale succes. I found another picture and even i am not sure, it looks like the rockers are incorporated in the cylinderhead - just like it was at the more modern BSA A65.
