A late A10 should be alternator with the 4 spring Triumph cluctch....not the six spring pressed tin BSA clutch...........anyhhoo,people replace the clutch with a Suzuki one ,cant recall which ,but the swap is well documented.........Incidentally the dragging clutch will smash your gearbox gears apart.,and sharp gear chips will score the shafts.............To cure this problem ,I fitted an army beezer clutch ,this freed easily,but tended to slip under power.,just had to ride the bike sedately .............Anyhoo,when I sold the bike ,it lasted only one day , and was on the news that night..........he tried to pass a bus on the inside as it turned left .
