Have recently aquired a Sammy Miller CCM 350T Hiro which has been modified, snell ported, Yamaha piston but unfortunately it has a broken 5th and 6th gear which the part number is cc08.13.106 and have no idea where to aquire a new or second hand one. Possibly even the whole gear cluster. I would greatly appreciate any information on how to purchase these or any Hiro components and any information on this bike would be greatly apperciated.
With Thanks Andy from Australia.
