Hi BS and Ollie,

All those Chonda type engines are 19mm / 3/4 size PTO shafts so as such a new Clutch half will be part of the order. Now that's ok if you have to change the clutch anyway, but if you have a machine with one of the original type Cast Iron clutch halves you'd move heaven and earth no to go away from that type as they are bulletproof and never wear out unlike the cheaper Aluminium die cast units constantly do.

As far as the handle bars clashing with these engines you'll probably find you'd require a pair of the handlebar adaptor plates to be fitted at the lower end where they attach to the chassis. Regardless the handle bar would have to be adjusted so that it fully leans backwards to clear the carby.

Cheers,
BB.
