rob it went on a 200 mile round journey and just sounded a bit funny when i got home, that night i took it to bits and the big part of the crank fell out because the timing side still had the gears on. i must say the whole engine clutch included was a mess, i managed to get a whole unit that a bloke had cut out of a bsa frame and that unit is what i rebuilt and have today, he put a water cooled suzy engine in the bsa frame and made a kneeler.
