Oceania is a region centered on the islands of the tropical Pacific Ocean.[1] Conceptions of what constitutes Oceania range from the coral atolls and volcanic islands of the South Pacific (ethnologically divided into the subregions of Melanesia, Micronesia, and Polynesia[2]) to the entire insular region between Asia and the Americas, including Australasia and the Malay Archipelago

yes agreed. and that model is produced in that region specificly for those counties. with the 3U6, 3W6, VINS
trying to find out the difference between the 3u6 and the 3w6 The 3u6 didn't come to the Australasia countries and i suspect it has an electronic ignition. There ia another thread with a guy who has one but doesn't want to tell us?

On the chart where is says 79-80 that was the manufactured dates. The manufacturing yesr is September to August. So the 79-80 is from September 79 to August 80. This makes it an 80 model year.

The 256 engines are not nessasarilybeter or worse than the 447 or 533 for that matter.
The 256 used some two stroke technology that turned out to not work so well with a four stroke. The biggie is the rod small ends. They used a needle bearing there. This made the rod end a bit thin and would get egg shaped under hard use. This led to rod failures.
Not a problem on most street bikes, just those used for racing.
Some say the way the intake and exhaust port angles and shape made on the 256 made them run better than the 447's. Some attribute this better running to different cam specs. It may be both.
I have never had a 256 engined bike to play with. I canonly repeat what others have said.

Any help on this? I have my frame vin, and I see 653 CC on the cylinder but i do not see an engine VIN......
Thanks!
^ yamaman's reply under breahn riley's question had the answer. This shows you where the vin is located on the engine: http://www.mikesxs.net/pdf/XS_Model_ID_Chart.pdf
It's on the front of the engine near where the front motor mount attaches to. If the engine is in the frame, the front motor mount kind of hides it.

Thanks for this thread. I was able to identify my newly acquired XS as a 1980 Jap model SG(frame # 3G5 000xxx)
But my engine is only stamped as "447". Is that (un)usual?

The stamp on the engine will be on the front of the case, next to the forward motor mount. The 447 is the type of engine.

yes I realize that - and it's only stamped with the number "447"

And that is typical. All the later engines sold in the US are "447."

So, no way to tell the year of the engine?

There should be the 3G5 000xxx stamped on the front, right above the oil feed tube base on the case. If it doesn't, it's kinda weird.
