I've had another hard look at this machine and I'm starting to wonder if this still has its original engine as there is a clip on the right hand side of the handlebar exactly the same as on the left side, only the RH side should have a throttle cable running down and clipped into place.
Either the whole control assembly has been removed due to its failure or the engine has been changed with a replacement unit which has the throttle and choke controls on the engine itself, thus the control unit has been removed.
Without closer shots of the RH handlebar assembly in the upper area it's hard to judge.
Cheers,
BB.
