stavely

Hi all, I need some help I want to get into the above forum but I've tried and failed over the last 3 weeks. Is it still operating? If so..... Can anyone put me in touch with a moderator or administrator to help me? the Board Administrator contact button just doesn't work. Cheers. In the meantime does anyone know if UK TDR 250 barrels & pistons are a direct fit onto a french TDR 240 bottom end? Or is the crank throw or something else a problem? How can a 240 be identified by its frame and engine numbers? Is there a significant difference in performance for the 240? Thanks all
