My new Long March, XY200GY-7
Hello,
I just got my Long March two days ago. I had a cruiser 3 years ago, never a thumper before. I had no idea it would be such fun. Roads? Who needs roads..
http://hotimg23.fotki.com/a/116_52/2...mage-vi847.jpg
Electric cables were not insulated. Amalgam tape.
http://hotimg23.fotki.com/a/116_52/2...mage-vi852.jpg
Bike vibrates too much if i reach 80km/h. How to fix this ? I've seen some bikes put heavy weight on the bar end to make it heavier, does that work?
Also, I've been told that i should not be riding over 60km/h for the breakin period, and i've read there is no such thing as break-in period on modern engines :confused1:. I'm going easy on it for now.
http://hotimg23.fotki.com/a/116_52/2...mage-vi785.jpg
No fuel meter, but tank has reserve, so i get a warning before im completely empty. Duel tank does not have a lock, and i don't think it's possible to fix this. Any ideas?

New steering clamp is different than the original that broke with Supersignet and different that the redesigned one posted here Hope this one does not break.

Also, the choke lever has three positions, i don't which is what. Any ideas?
Road tires felt weird for the first few rides. I could feel the bike wobble too much. But it's the first time i've had a dirt bike. Getting used to it now, i still have to try to breaking hard on some empty road and see if i can handle the bike comfortably.

Re: My new Long March, XY200GY-7
Anyone else has this bike? What cruising speed are you getting? I am comfortable at 70 km/h and if i try to go faster the bike vibrates too much i cannot hold on anymore. At 80, the rpm shows 5k on flat road.
Any suggestions? I'd like to get 100 or 90 km/h.
Other than this issue, im really happy with the bike. Climbs mountains easily, and it is really fun off road. Also, i dont mind potholes or speed bumps at all; barely notice i went over them.

Looks like a great for doing china!
How many cc is the dog?

Re: My new Long March, XY200GY-7
I'd be worried about the vibration, no modern bike should vibrate that badly. Where do you feel it? At particular revs or does it grow with speed? Front end or back, through the bars mainly or through the frame from the engine? I know you may have done it already but check the engine mountings first and look at obvious things like is chain correct size!. Many things can cause vibration.
I'd have a good look at the alignment and connection of all running parts and the suspension too (are the shocks low on oil?), maybe a bolt out of line on rear or wheel rubbing, something like that.
We need to know more about what and when you feel the vibes. Does it vibrate when revved but stationary etc. Under acceleration or deceleration or both? What happens when you (carefully) pull in the clutch at speed (this isolates engine).
It could be many things like steering head not tightened up enough, bad rubber pattern on a tyre, even wrong pressures, wheel rims unbalanced, an engine mount cracked, sprockets and wheel bearings loose, right down to nasty things like crank shaft. Sorry not to help much but need more info. Be careful for a while and tell the dealers if it isn't something obvious.
After all that is sorted, you can also get rubber mounted foot pedals!

Re: My new Long March, XY200GY-7
Felix, thanks. I just love getting lost on this bike. Dog (Milo) eats as much as i do. I think his stomach is ~200cc, heart 50cc.
Vibrations I mostly feel through the grips. Also if i close my knees around the gas tank. Vibrations only get really bad if I reach 80 km/h. Then i don't feel confident going any faster. I can feel the vibrations die momentarily if i pull the clutch, just until I'm in gear again. But I can check again tomorrow, I'll keep the clutch closed and see if it rolls smoothly. I will also try to rev it while stationary, in neutral or with clutch pulled?
I should mention that it's a bit smother now than it was first 200-300km. So far I've done 650km.
Dealer says it vibrates because of the big rear sprocket, he says bike is not made for road use. I don't buy that Chinese way of trying to :bs: me. I don't want to change the rear sprocket because I really like how the bike handles off road; i don't think it will behave the same with a smaller one. Bike is brand new from the oven, nothing was obviously broken, but i will have a closer look at engine mount tomorrow. The only odd sound is my keys rattling.
Thanks for the quick reply, i'll update tomorrow.

Re: My new Long March, XY200GY-7
Slabo,
Thanks for sharing your experience with the GY7, nice to see you racking up the miles quickly. :thumbsup:
About the vibration.... that's the way they are. I rode Supersignets GY7 last spring and I couldn't get over how much it vibrated above 75kph. The dealer is correct, the bike is not geared correctly. Ninety percent of the bikes sold here do not have the correct gearing for their intended use. Play with the sprockets, they are a cheap easy fix to the problem. If there's enough space up front, try going up one tooth.
Enjoy your bike!
Cheers
ChinaV

Re: My new Long March, XY200GY-7
tightened a few bolts and nuts, bike ran smoother. Also put some more air in the tires. Still vibrates, but not as bad. A friend of mine suggested swapping the aluminum handle bars to steel or carbon fiber. I'll consider that after the break-in period.
Anyone knows what are the settings for the choke on this bike? They don't mention anything in the English user manual.
http://hotimg23.fotki.com/a/222_221/...mage-vi736.jpg
I would like higher cruising speed on the highway. So i have to either change to bigger in front(one tooth bigger), or smaller (how much smaller?) in he back. Not sure what is better in my case. Any advice?
Not sure there is room to go one tooth bigger on the front.

Re: My new Long March, XY200GY-7
Regarding the choke: up to choke, down to open. But i really have no idea which position for half open....:eek2:
Sprockets: i'm no guru so you may want to wait for better advice from some of the more experienced forum members, but it sure does look tight for an extra tooth up front. What are your current sprockets? That might help to guess how many teeth to remove from the rear.
Someone correct me if i'm wrong please, but i think this is how to work out the change that a new sprocket will make:
Say at the moment you've 47 teeth and you want to switch to, say, 41 or something. Also let's take an initial speed of 70kph at a given RPM. You do:
47/41=1.146
70*1.146=80.244
So at the same RPM in the same gear, your new speed will be 80.
This method doesn't say what will happen to your acceleration though, just speed.

So its open or closed, but there are three settings. there is a middle setting, why?
I'll check how big the rear sprocket is and post back.
Also front mud guard is pretty useless, I saw another of Shineray's offroad bikes has a quarter mud guard hanging separately and lower than the first. Any idea where to get those? Dealer has no idea. I'll try to remember to take my camera next time im there.
Thanks for tuning in. Good luck with your next bike felix.

WLJF 56-428. I think that means that the sproket is 56 tooth, and it uses a 428 chain, what is a 428 chain?
Anyone replaced the seat on this bike? I think am developing ass calluses. maybe that's another way to make the seat comfortable.

Hi slabo, don't worry too much about it, i never use the middle one. Choke to start it and then open when you're running.
As for the sprocket, 56 is loads of teeth and i'm sure you could afford to lose quite a few. Maybe ask supersignet, he's had a couple of these bikes.

Check exhaust system tightness too. I find that tightening every bolt I can find helps the bike run smoother on my China machine.

Re: My new Long March, XY200GY-7
I sold my GY-7 to a good friend of mine because I won't be able to ride it this summer. He's planning on taking it up through inner-mongollia this summer. The gearing from the factory is pretty bad. 1st and 2nd gear are pretty much usless on all but the steepest inclines. We dropped to a 46 tooth sprocket on the rear and the bike is doing much better around town and is getting a little bit more top end, but the bike isn't near the sweetspot yet. It's going to take some trail and error to get it right. I'd be tempted to try ChinaVs Galaxy 230 gearing on the bike as the engines are basically the same.
Make sure you tighten all of the bolts... My first GY7 didn't vibrate badly, but maybe that's because all the vibs were getting sucked up by the tripple clamp. My second vibrated, but after tightening up all the bolts and changin the rear engine mount bolt and sprocket it is a lot better

Re: My new Long March, XY200GY-7
Thanks for all the precious advice.
I went to the dealer and they replaced my brand new dead battery, now i don't have to kick start my bike anymore. They took it off another "new" bike, so good luck to the next guy buying the same bike. They also replaced the cable to indicate what gear i'm in, it was pinched during factory installation.
I also added an extra mud guard in the front, pictures below.
http://hotimg23.fotki.com/a/220_163/34_25/P1050052.jpg
About replacing the rear sprocket, the bike felt underpowered going up bad trails. No problem with one person, but two up with ~10kg camping gear, it was a struggle. I had to stay in 2nd or 1st gear, ~20km/h and I stalled one time (1st gear) and dropped the bike; passenger was not happy about that. But I can't blame it on the bike, I think I still need more practice. I'll try to drop a few teeth and try again.
-
Re: My new Long March, XY200GY-7
I think you have to add teeth to get more low gear power, not drop teeth, unless I misunderstood something? Good to see you are out and about on it, don't trust the battery for long, I went through a couple from the manufacturer on my Kinlon 200GY before I bit the bullet and purchased a decent one! Your passenger needs educating, in return for not walking they act as stabiliser, rear airbag, two-sided adjustable prop stand, cigarette lighter, neck scratcher, chocolate unwrapper and tent erector. And they keep the rain off your back. If a GF, they get to keep their hands warm too but tell her not to hold on there too tight ...

Re: My new Long March, XY200GY-7
My original complaint was that the bike was vibrating way too much at ~90km/h. Fixed that after tightening a few bolts. But I also wanted a smaller sprocket in the back to be able to cruise ~100km/h easier.
After I tried it in no road conditions, I am having second thoughts about changing to a smaller sprocket. I think it's worth trying, i can always put back the old sprocket.
Take the chain off, replace the sprocket, then put the chain back on, how do you do that? Can someone describe the process? I'm still trying to find the service manual for the original Honda XL185.
Judging they way they worked on my bike so far, i think i'm better off doing the work myself instead of just trusting these wrench monkeys.

Re: My new Long March, XY200GY-7
Hi Slabo
To get a lower gear ratio (more response down low, lower top speed) either get a larger rear sprocket or a smaller front. down 1 tooth on the front is almost equal to up 3 on the rear. It is easier to change the front sprocket than the rear on most bikes, the other advantage is that often you can change one tooth size on the front without having to get a longer chain or shorten your existing one.
To get more top end (faster top speed with lower revs, less responsive down low) is the opposite up size on front sprocket or down size on the rear.
Hope this helps

Re: My new Long March, XY200GY-7
Hi slabo
This may sound strange as i only have a 125 lifan ,but that would vibrate at speed 50 -65 mph,way hay,But i bought some alloy rims and had them rebuilt buy a chap near me who restores british bikes and lo and behold the vibration has gone(even thrashing it doing 70mph on the clock).so you never know maybe try tuning the wheels,i did notice before the new rims that the spoke tension was a bit hit and miss,but now they are nice and evenly tensioned,it may be worth a go

Re: My new Long March, XY200GY-7
Thanks for the advice joe. On my last trip, i found out that i'm going 60km/h from my GPS, when the speedo was showing 100km/h !!!
That convinced me to throw out my tires, it's just ridiculous cruising at 45 km/h, even scooters were passing me. Shame, shame.. But maybe with new tires bike will feel more balanced. Report coming soon of my trip from Kunming to Chengdu and back.
I made 5900 km on the bike so far, and no major problems so far, but shifting does not feel as smooth as before.
battery dead again! I'm buying a new battery, not from dealer. Anyone has an idea what's a good battery brand in China?
Thanks

But I was in a pinch, was heading up for a two days trip camping and just did not have enough time to shop around. Found a dry-type battery at a motorcycle shop on the way, cost 120 rmb. Changed the spark plug for another 20 rmb... Did not take a picture of either! I'll try to find the battery again next time i go there.

Hi Supersignet,
Still around? What sprockets did you change to? I'm planning another long trip and I'd like to sort out the gearing on my bike. Any advice on where you got your gears? I'm heading out to the local bike market tomorrow, not hoping for much though. If not, I'll get something from Taobao.

Re: My new Long March, XY200GY-7
Just curious if anyone else has one of these. Would be interested in exchanging info regarding repairs, any issues. I bought mine used and it runs great. The bike was ridden from China down to SEA. Would love to get some manuals or stuff like that. Having a thread dedicated to these would be cool, though owners seem to be few and far apart.

Re: My new Long March, XY200GY-7
hi, sorry for the late reply, haven't been active on this forum lately. There's this shop manual of the Honda XL and similar here >> http://www.motomanual.com.ar/index.p...ileinfo&id=724
It's in Spanish, and you have to register to download it. Also, I'll upload the rest of the files I have, like parts list and other shop manuals.
-
Re: My new Long March, XY200GY-7
Thanks for that slabo. I guess I'll have to brushup on my Spanish, lol. Well better than no copy at all, downloaded it and seems great. Would appreciate anything else you have. I'be actually got Pete's bike, runs fine though as everyone knows, these bikes are underpowered but for the SEA countryside, it suits me fine because doing anything above 100 increases your chances of dying significantly, lol. Kids on the road, huge potholes, chickens/cows, etc. Cruising at 75-85 is fine with me. Gives me more reaction time to look around. Did you have trouble with maintenance on your bike? The guys here can do pretty much anything but I've kinda been wondering about spares, how repairs will go etc. Haven't had anything major yet so don't know how many Honda parts are actually interchangeable.

absolutely right about speed limit on this bike. Stock, it did a max of 65 km/h according to GPS.. And I wondered why little scooters were passing me all the time. when I changed to smaller sprocket I got a decent cruising speed of 88km/h, like you, I was happy with that with all my gear and stuff on the bike. At that speed, i've got plenty of time to dodge chickens and kids or whatever wants to run across country roads.
the good thing about it, it's got good brakes, and I never saw a bit of rust on the bike eventhough I went through a lot of rain.
Maintenance ? haha... that's a nice joke for all the mechanics I met in Yunnan and Szechuan. If it turns, it's ok. Maybe some burnt out motor oil on your muddy chain, change of oil .. anything else, I had to fight to get anything done.
The nice thing is that the bike is super simple. But I had a hard time finding some parts, I remember I couldn't find a rear sprocket, had to grind a similar one to fit my hub.
I zipped and uploaded the folder I have on the long march, and the bike it's copied from, XL185 and it's more modern equivalent, XL200 .. link here >> http://www.filedropper.com/shinerayxy200-gy7

Re: My new Long March, XY200GY-7
It's for reading while on the road! lol.
Weird, normal cruising is probably 70-75 for mine and though I didn't count the teeth on the rear sprocket I'm 99% sure it's stock. WIth GPS I recorded maybe 85 at 8000RPM. At around 6000-7000 it did 70-75. But I like to keep it in the 6-7k range so I'm cruising at around 70 with a lot of kit (GPS as speedo is broken). That's with kit on but even then, having more oomph would be nice. And like you say the brakes are actually quite good, better than the old XR/Baja rentals I used to ride on. Or rather the brakes feel more controlled.
I don't expect I'll be able to find spares here in Cambodia (actually, it's 100% certain that there are no spares here as I'm the only Shineray owner here), but the locals can usually make something that'll at the very least be good enough to get you to a bed and a meal if on the road. In the capital they have some decent bike shops that can probably make stuff happen but spare parts would probably be expensive to order from China. Taxed per kilo I believe. But same as China I guess, a lot of them are just grease monkeys and they'll say they know how to do something fo fear of losing face, then just tinker around not knowing what the hell they're doing. I'm just hoping Honda parts can be used or modified fairly cheaply to fit the Shineray. I guess time will tell.I'm going on a big trip in maybe 2 weeks (1000km+), will be doing lot's of off-road as well. If anything happens I'll post about it here I guess. It's only a matter of time before important parts are needed (it's got maybe 10-12k I figure, which isn't much but still...). I hope the time comes later rather than sooner but I'll post about my experiences re:parts here if and when that time comes.
DO you still own a bike Slabo? What kind? I'm using the Shineray a bit as a daily driver though I intended to keep it mostly for big rides. Suzuki Smash as a small city bike.
