Well, it's been a while since I've updated this but rest assured, work is still continuing. I managed to find a replacement head, piston, rings and gaskets in Japan and had them shipped over (at great expense)- These arrived just a few days ago.
In the meantime, most of the frame is stripped and, like the wheels and other parts, suffered from the rust bug under the original paint. I'm in the process of organising paint- Originally I intended to get it sprayed by a car painter but the cost of the cylinder head etc meant I'll have to paint it myself to save some money
A couple of questions for the gurus: The previous owner filled the crankcase etc with oil to stop the parts going rusty etc- What's the best way to remove this (as well as any grime that may be in there?) The new piston has a dried film of oil/protectant (presumably to protect it in storage)- Should this be removed before installation? When reassembling, is it ok/good to have some fresh 2 stroke oil in there to lube things before the fuel/oil mix is drawn through etc? (I'm intending to replace the oil injection system with pre-mix as I suspect a leaking oil line caused the original seizure)

yeah id say that piston is fine
try a set of rings from a qingqi D1E41QMB but look at them first make sure the alignment pins are the same or close

It has been awhile since I have been here. I am the fool who recommended shipping the engine to Vietnam and have it built right. I have a 250 CC Hoffman motorcycle restored in Saigon awhile back.. Got awesome work as a very good price. anyway, I do agree with your rational for doing it. As long as you know it is a 20-30 mph smoker when you get it done, It will not run with the smokers you typically see being used in the Orient.
Glad to see you are still working at it. Re the paint work, you can do the priming yourself without much concern. I would consider using almost any brand self etching primer. Most Auto paint stores can help you select materials
Sorry the new parts were so expensive. the real cost of restoration is often terrible. Hope you find some thing more fun and lees expensive to get you off the computer some of the time..
Good luck lefty2
