Notice that the engine is stamped with Shineray on it, I would say that the engines used on the Shineray motorcycles are manufactured by Yingang.

The water cooled DOHC 4-valve is a copy of a Honda NX250 engine.

That engine 170MM can be found on several Chinese motorcycles.

That model appears to have EPA approval, unfortunately they have no filings with the NHSTA. They are registered under the WMI of LY4 but have no coding document on file.

I say it appears to have EPA approval because it is being advertised for distribution in the USA. This model shares a common engine with other brands….it would be logical for them to share information and work collaboratively in establishing parts support.

I still think the market is very limited in the USA, they need to be very cautious entering unprepared. Full documentation and parts support would be prepared. That and cooperative ventures with others to share operating costs. Dealers want easy and simple systems online indexes linked to schematics.

I believe that it is difficult for them they are producing high volumes and selling them, but the lack of documentation and parts leads no were. It will ruin the reputation of any brand, simple and easy to access parts lists based on schematics are required.

This is good example of how it should work.

Actually tracking VIN numbers is even better, because the model number and year can be encoded in the VIN. This way if the part changes on a model then it would also change the links. Then each time parts are ordered it would also track consumption of the parts. That could all lead back as a report to the primary supplier. They could see the flow of parts and also see if certain parts have higher obsolescence then others. That’s how things that break too soon get taken out or off the assembly line, they get replaced with a better parts that last longer.

Here is a satellite image of the YinGang factory.

People that work at the factory live in dormitories. That's communal so they get paid less but housing is included.

Here is a photo of the housing.

I found this advertisement for a Yingang bike, they call it the Mountain King.
They offer it with a 200cc SOHC engine, it a great commercial.

I really like the ad, but I am not crazy for that bike but I like the concept of it, all the racks would make it very practical. I would like to see it with a mono shock and more rear travel, heavier shocks in front maybe.

[katoranger]

I wonder how much that tank holds. Looks to be larger than most china bikes. Patterned after the ag bikes offered everywhere, but North America.

The racks could make it a great slow pace adventure bike.

[Weldangrind]

I'm ok with the twin shock setup; I'd bet that they can handle more weight.

[katoranger]

I am fine with twin shocks too. I believe they fit with the bikes intended use.

Like this Yingang also, it called the YG200-9 it comes with the 163fml engine standard or it can also come with the 250 version 167FMM 230cc. The bigger engine has the same hp 15.64 as the 200 but at lower rpm and has more torque then the smaller with only (15@5500) at higher rpm the 230cc has (17.5@7000)

I just like the looks of it and it has a 33” seat height, which I like as well. I think the 230cc engine would have a bit more pull at the higher end?

It’s a different looking bike, its not a dual sport but a totally street version of the same configuration, very light and nimble with a 4.10” wide 16” rear tire and a 3” wide 17” front.

[Oengus]

I pointed out this website before…
http://www.motosportparts.com/

They have bikes listed for sale and the prices are very low except for one that is listed at $10,000.00 which is obviously a mistake.

But the they have a dual sport listed for sale at $950.00?

I registered and then attempted to process an order, it resulted in it telling me that there was no available shipping to my address? I would not buy it, just wanted to see what the shipping costs would be or if the system even worked, it did not it hit a glitch or dead end.

It's not a bad website, but it has some serious flaws, it looks ok but its buggy.

This site is linked to the YingangUSA http://www.yingangusa.com/ site and that tells me that eventually you could see the Yingang bikes being sold on that website. It seems they are clearing out the old SUNL inventory or attempting to? I am not sure but it seems it is the same people that operated SUNL.

[Oengus]

That site also has a forum...its hilarious it looks like it was hacked into by some people that only speak french? Its as if it is a hang out for bots?

I think SUNL went bankrupt, they spent a ridiculous amount of time building that website and it does not look to be anything more then an experiment? Typically beta sites are not on the public domain, they usually build and test on a intranet not the internet. That being work all the bugs out before you make a bloody fool of yourself and damage your reputation.

Somebody could clean all that up....but repeating the same behavior and expecting different results is in fact ignorance.

Sometimes with respects to buggy programs and crazy complex over the top websites...it can be better to just start from scratch. In other words it is too complex and does not work well.

Ok it looks like the Yingang engine is based on a Yamaha and it the 250 in the FZ16 not the NX250 or a Honda and Yamaha share an engine?

[Oengus]

Actually that’s is a Chinese engine transplanted into it, the Chinese engines is not a copy of a Yamaha FZ-16 they have 150cc engines.

Here is a thread on the swap on an Indian forum….the individual paid $1,300.00 for the engine. Bought direct from the factory and had is tagged with his original engine serial number…tsk tsk.

[Weldangrind]

That's pretty funny that he had the same number stamped, but this engine is liquid cooled. I guess that anyone other than an enthusiast would never figure it out.
