BSA B40 Motorcycle, Pre 65 MX

Hi. I am looking to swap my BSA pre 65 mx for a British road bike. I would prefer a Triumph or BSA twin but I will wait and see what I get offered!
The frame is a chrome twin down tube replica with oil in the frame but I can't see any numbers on it. it has betor forks and yokes/gremica hubs/works performance shocks/renthal bars with tommaselli levers. B40 GB 350 engine just had a rebuild on methanol. victor h/c piston and head. ported with 30mm carb and pvl ignition and the tyres are good. I have built a new metisse for this year so this one is no longer needed.
I value the bike at £4000. advertised elsewhere and can be removed at any time thanks for looking.
