No-one else has replied. I've never heard of it either and I thought I'd seen most things in the '70.s The motor looks Kawasaki like. Was it sold in the UK ?

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

ok progress today is that i managed to split the cases...
very easily infact, another first time for me was that there was a gasket between the crankcases,
that made the job very easy indeed,
here is the evillness that is my bottom end :cry:

so crank cases split i have another problem, there is a little pin that is on the right hand of the crank that is there to spin the gear that spins the disc valve,  which means i can't get the crank past the damn bearing...
am i right in thinking that the bearing should move out wards and not into the bottom end??
it has a circlip in place which makes me think that

well i managed to get that pesky pin free... very easily infact,
good old side cutters did the trick no bother,
bearing stayed in the case and the crank slid through,
hammered the bearing free,
and bobs ya uncle,
and here is the culpret...  32years with out being started and this is what you get

i did some measuring and found that the bore is 42mm and the stroke is 43,
so that makes this bad boy a staggering 59.57cc  wooo hoo.
can you feel it???
