nah im back in new zealand now,
the previous owner (the guy who bought it from new)
seemed to think it was inported into new zealand by general motors,
and that it was based on a yamaha engine when the thaiwanese bought yamahas tooling gear,
i suspect its a kawasaki or suzuki copy
it has the rotary disc carb system with the carb under the right cover, similar to the ts50
bottom end is seized at the moment and i have stiped down to cases
ill have to buy some splitters today and see if i can find someone who will supply me with some new bearings
