Genesis xm200gy-b

Hello all. Thanks for all the great information here. I'm living in Honduras, and just purchased a chinese dual sport. It's my first motorcycle, and I assume this is the same motorcycle with just a different name on it as the ones you talk about these forums. Can anyone verify that this is the same motorcycle or at least same type (which means the mods should be the same)?

I bought a new Genesis xm200gy-b, for around $1300. Found here:
http://www.global-genesis.com/produc...XM200GY-B.html

Looking at the sticky labeled "zongshen sierra 200gy" thread (awesome info!!!), I think the first thing I'm going to do is purchase a Mikuni 30mm carb.

Question: Do I need to "jet" the mikuni 30mm? I've never worked on a carburator before.

I'm also thinking about putting a few holes in the end of the exhaust as well.

Nice bike and welcome to the forum. That was a good price. We are looking forward to seeing pics of you and the bike in Honduras.

Welcome! Nice looking machine. We'd need to see some close-up pics of the motor before we can guide you.

Indeed, please do post some photographs of your bike. You can learn how to post photographs on these forums by reading the following thread.

Here are a few pics. Can anyone tell me anything about the engine and carb? The biggest complaint I have is that when I hit the gas hard, it boggs down. From what I've read, that could be the jetting in the carb. I've adjusted the carb to have a nice idle after warm-up, and no matter how I adjust it, it doesn't change the bogging.

I forgot to take some exhaust pics. I'll try some tomorrow when I'm changing the oil.





Looks like it already has hex bolts on the brakes



And I won't have to cut the gaurd in half







That looks like a weld, but it's actually a beed of grease

Still need to take the plastic off around the gas tank.

Thanks for posting the great photos. You bike looks great!

You have a different motorcycle than my Zongshen 200GY-2, which employs a copy of a Yamaha engine. Your bike has a copy of a Honda engine, a different front brake caliper, and a different, left crankcase cover. Your bike also employs a different carburetor, sprockets, et cetera. Therefore, the threads you are reading in the "Zongshen Sticky" don't apply to your motorcycle. However, you will still find a lot of good information about your bike on these forums.

This looks just like the TMEC gy200 discussed on a few threads. Not sure what engine the Genesis company uses, but the US version uses the Zongshen 167 FML. I had a custom rear sprocket with 40 teeth made for me, but your sprocket (hopefully) is one of the more common Honda-clone sprockets which are far easier to find. Looking at the photo, it seems to be the Honda type vs. whatever we get here in the US, so if you want a more usable bike, if your bike has a 56 tooth rear, you would be best served with one in the mid-40's. If it is the same engine as what I have, you should already have a 17 tooth front sprocket.

That engine is based on the venerable CG125, which is very popular in the UK and Brazil. If the carb has three screws holding the bowl on, it is a Keihin clone, and I've had much better success with a 30mm Mikuni. If you're using the stock air filter and muffler, the 100 main and 20 slow jets in a 30mm Mikuni would probably be ok, but bigger jets are needed if you begin to modify.

In this pic, you can clearly see the pilot mixture screw, which is on the underside of the carb. Gently turn it in, counting the number of turns until it is barely seated. Unscrew it to a different point and go for a ride. In other words, if it was 1.5 turns out, try two turns out and see if it improves. It is responsible for the transition from the idle circuit to the main circuit.

As with Culcune, I was also going to comment this bike resembles the TMEC 200 sold in the United States. However, I like this bike better than the TMEC 200, since it appears to use Honda rear sprockets. Also, I like the conventional, 18-inch and 21-inch wheels.

Thanks for all the comments. Very helpfull info. I left town for the weekend, so I didn't get to work on it yet. When I do, I'll try to find some distinguishing marks on the engine and carb, and try to take some pics without the plastics on.

I've tried to adjust the carb screw a bit, but still get the bog no matter which direction I put it in. I'm going to try to ride my mechanics and see if he has the same thing.

video of my carb

I took some crude video pulling my carb out, trying to make some adjustments.



Can anyone recognize it, or what it's cloned after? The numbers on it did not come up with anything in a google search.

There are two external adjustments. One can be seen and adjusted while it's hooked, I assume this is the normal gas/air mix The other has a similar screwdriver adjustment on the bottom, but can only be adjusted after it's removed.

I adjusted it a few times, and I still get the bogging at full throttle.

It's not that I want to race this thing, but when I'm going up hill it affects the speed. It could also be a safety issue, if I need to accelerate around someone.

Also, The black tube that comes out of the bottom of the carb, is that supposed to hook up to something? I think it just hangs there.

Thanks again for any input.

Oh, and here is what the throttle sounds like (garbage)

The screw on the underside is the pilot mixture screw, which is responsible for the idle to main circuit. it must be adjusted while on the bike, with the engine warmed up. If you can't access it with the carb on, you need to buy more tools.

The screw on the side is the idle adjustment.

The carb is a copy of a Keihin that came stock on Honda XR200's in the eighties. The 30mm Mikuni is a much better carb.

Thanks for the insight. I'll see if I can get some needle nose or something and adjust it tomorrow. But, I'll probably order the Mikuni anyways.

What about the black hose out of the back? Does that need to be hooked up to something, or just dangle? It kinda scared me as it was near the chain.

The hose at the bottom of the carb is either a drain hose, an overflow hose or both. It just dangles, but make sure it doesn't contact the chain.
