In order to fit the new VM34 carburettors to the RD400 top end Jean-Marie has machined adaptors up to do the job!
He is working on solving a persistent piston failure problem!
Jean Marie made everything himself, except painting, and the re-boring of the cylinders!
Thank you to Jean-Marie Lecoeur for providing the photos and information about his project.
