hi i have just got a k plate cagiva super city 125 it needs abit of work doing to it i have a few problems finding supercity parts and i was wondering if i can use parts from any other model? i need, a throttle cable, a clutch cable, ignition barrel with key?? also the chain i have is really tight with no play what so ever, i think the last owner may of put the wrong chain or sprocket on it, so does any body know what size/ measurements the chain and sprocket should be??
