Thanks to DCarver over on the 1300 site who posted this pretty cool Oil video.
Check out:
European, Chinese, Italians?

Fortnine!  They have a lot of interesting videos on Youtube.  They sell out of Montreal.

Interesting video. I rode a Royal Enfeild 500cc across India for a month a few years back, they are crude and rude but bullet proof. I put about 5500 clicks on that bike and it had about 30000 before me and it didn’t skip a beat. 

One thing not mentioned in the video is the mileage on the oil samples.  The photos of the oils clearly show different level of usage (darkness of the oil sample,) with the oils from the bikes they say were the worst being the darkest.  More miles = more particulate matter in the oil.  

 

I think it was more that all the bikes tested were "brand new" and the colour of the oil is a indication of the residue of... crap that was left over in the machining/building phase of the engines, all the oil was the same oil just ran in each bike for a set amount of time and then drained out to be tested. The Chinese obviously broke the machine with the crap that was left inside the engine after production.

Kind of related. this was several years ago, but I read somewhere that if you get a chinese mc, first thing you should do is replace the fasteners as they used cheap thru-out. supposedly, doing so would reduce the number of problems.

In 2006 I bought a brand new Roketa 200cc motorcycle for $1,300. It was so poorly built that after every ride you had to fix something. It was shot after 2,500 miles, a patchwork of repairs. The only good thing I have to say about it, is it got me back into motorcycling after a 25 year absence. 

Here is another video of carburetor vs fuel injector.

A group I'm involved with purchased a bunch of dual sports offered under the brand "TT". These bikes looked to be dead on copies of a Suzuki DR 200. I was told we got them for $2,100.00 each. We dumped all of them within two years. They were just plain undependable.

I'm not so sure.  The darkness in the oil indicates usage.  No oil looks like that fresh after install.  Not to mention these samples came from contributers.  No way those engines are straight off the showroom floor in all cases.

So gave it a good second watch and each bike was on its first 1000km service with manufacturers oil and filter, that oil the was in the bike from the manufacturing line along with any residual “crap” from building/material. So that seems more Like a balanced test, apart from some of the bikes may have had few more or less Km’s done  at the time of the oil samples.
