Sprockets and chain for my Shineray XY200GY-7, the vibrator
I've been putting this off for a long time now, but I'm planning another trip next holiday and I have to sort this before then. Bike vibrates a lot, and according to GPS, it reaches 60km/h when rpm is ~6k.
Basically the bike is geared too low. Already have 9000km on the bike so far, so changing the stock chain may not be such a bad idea.
Is this some kind of an O-ring chain? All I can see written on the chain is IE, KMC, 428U0
http://hotimg23.fotki.com/a/113_106/...Sproket896.jpg
Another view of the chain. From the open side, looks like there is lateral space between one side plate and the other.

Front sprocket is a 14 tooth. Not much space left for a bigger front, can I do anything about it? Not much metal to grind also.
http://hotimg23.fotki.com/a/222_221/...mage-vi841.jpg
Rear sprocket is a 56 tooth, mounted by 4 bolts.

Another view of the rear.
http://hotimg23.fotki.com/a/222_221/...3/image-vi.jpg
Any suggestions? I'd like the bike to cruise at 100km/h on smooth asphalt, but i'd be happy with 80. Also important is I can still get out of hairy situations off-road.
Any advice appreciated,thanks

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Looks like an O ring chain. No room for a bigger countershaft sprocket so you'll have to go smaller on the rear. If you know the engine's internal gear ratios you can used www.gearingcommander.com to figure your speeds at different RPMs. I suspect you will want to go to a 42 to 45 tooth rear.
-
Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Yes, down that far and you will get what you want. The ratio will be around 3 which is good enough I think.
The 428 chain should be OK, used on many such bikes but check the new sprocket matches it. No signs I can see in these pics of excessive wear but you will have to get a file to remove top of chain rivet and a cheap chain breaker and a new master link and clip or riveter and work out how many pairs of links to remove.
Hairy situations off-road vary but are usually corrected by being in right gear at the time and clutch/rev balance. You should still have enough in first/second to use. Send me your address by PM, I have a 'basic skills' DVD I got in a mag that I will copy and send you.
Look carefully at that front sprocket cover and the wiring on the left, perilously close to being pinched I think. Tuck it back safely somehow.
Have a look at engine mounts and other bushes where you can, also check what you feel able to of alignment of wheels and spring mounts. Just use common-sense mate, look at tyre wear patterns for problems that may be indicated. Vibrations can be from many things unfortunately but if the engine is running and not labouring, the chain and drive alignment is straight, engine mounts are solid and wheels aren't offline, it should even out. Wiggle the wheels to see if bearings and hubs are OK. Check spokes too. Sorry, but not all too hard. You will get there, as I always say, if I can, anyone can!

Oh now Mr.Jape is an expert on sprockets, maintenance and talking to female bots?:riding:

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
56 Tooth rear is GIANT, take hugemoth's advice and look for a 42 or 45. The question will be weather or not you can actually get one...it's so hard to find different size sprockets for Chinese bikes unless you take your old one to a market and try to match it up. 9000 kilometers on a stock 428 chain = garbage bin. Be sure to change all the parts together, for what they cost, it's not worth taking the chance. Get a couple extra master links to take with you, could save the day.
Cheers!

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Not an expert, I always make that clear, just trying to be helpful and share the limited experience I do have and pass on what I have read here. If you know better or different or know of information here or elsewhere, please pass it on Barnone. It all helps and people can ignore what they already know, but also one may notice something like that wire that they may have missed. Its not just me being a :jerkoff:
Seriously, and not necessarily as you intended, if you or anyone does find me a pain, or any other member (there are always differences of personality on international forums) you can go to their profile and click the ignore button! I never use it, as I am quite thick-skinned and know many of my own faults. You don't get body language on forums and you can miss subtle or even not so subtle variations in humour and style. You can also use PM if you are not sure or if you want an argument in private. I have made some good mates like that over the years once the air is cleared!
I also notice that some posts asking for help or introducing folk get lost at slower times and that some folk miss out on help and welcome. Forum members come and go and the real experts are often away or busy. I have plenty of time free because I am disabled a lot of the time so stuck in front of this infernal machine for contact and information. Thus sometimes I try and add to the conversation or lead people to search further into the masses of info here for themselves.
But I do get out there sometimes and ride about and play with the bike when I can move OK as a n umber of my threads will illustrate. When I was younger I rode all sorts of machines all over the place and I remember some of that stuff too. I miss it badly, the machines, the people and places.
I find the internet amazing, it takes me to a wonderful world where I can share the experiences and viewpoint of others and maybe add my own. Not just motrobikes, I do have some other interests!
When it comes to 'bots', I am privileged to quietly be a moderator here when CC and others are busy (and in other time zones) and sometimes I notice or get a message from members reporting a bot or possible bot to be removed as they can lead to phishing and other dangerous sites. We aren't always right so sometimes we let them sit a while and see, like the post you refer to. Soem folk don't say much, don't mean they are bots but they do have some patterns you notice, one of which is the style of post, however that can also be language or shyness.
Being male and unmarried I often chat to females, you never know ... female bots, well there have been a few that some of us chatted to here and there. Embarrassing but fun. It may not have been felix but for some reason I enjoy pulling his leg. Must be his cheeky smile? He will tell me if I piss him off, I am sure, and maybe to my face when I finally get to China. :riding:
Otherwise he and others I chat to on and off forum will get a beer or two.:goodtime:

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
jape, the pinched gear indicator cable is already replaced. The dealer took it off another brand new bike from the shop, same for the battery and the front sprocket clip. Those are older photos, so it's probably worth changing now.
Here's an exploded diagram of the rear sprocket assembley. I don't see any alignment washers anywhere. Maybe not shown.

How do you know a rear sprocket is a good match? Anything other than the number of bolts, and chain size? I'd like to know if the sprocket matches before I take it off.
What's a good brand for an O-ring chain?
-
Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Looks like yours bolts straight on without the alignment bushes in the hub that mine has. Replace bolts with better quality ones maybe. I would go with Humanbeing on sprockets and chain, he knows more than me by a long way. Those links both Google translate to "JH125L cabbage" so I think that means yours will take JH125L cabbage dirt-bike sprockets ...
Dunno if the extra width of 520 sprockets all through and chain would mean you have to change the chain guide and other things for clearance so unless the other Shineray guys in posts here say you can change, stick to 428? Suggest a search and another good read! Check the triple tree as they can break .... get yourself a brandy and read all about it.

Jialing JH125L is legal copy of 8*"(???) XL125S. That's the commonest GY bike config . If u are unsure, ask Qs... to those TB shops.
You can compare urs in JT sprocket's catalog 1st.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
428 drive components are kind of nice to have in China, as you can always find a shop with 428, 520 is a bit less common. 428 is also lighter, so it's like getting an extra 10 horsepower...well, not really, but every little bit helps.

Hey jape,
Sorry if I offended you with my lame attempt to be funny. After all your claiming to be an inept mechanic I couldn't resist.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
You didn't! Not at all mate, I am an inept mechanic, pretty inept at most things I do. Born and bred, a lazy, good-for-nothing dreamer.
I just decided to reply fully in case I had pissed you off like I did one bloke from Florida recently, using the post in explaining a few general things about forum as well. I am trying to be a nicer, more responsible human being as I get older and as we all get closer to judgement day in 2012. It is easy to misunderstand on forums and on a bad day that leads to misunderstanding. I enjoy your posts and watch for them here and elsewhere.
I used to be scared of you, thinking 'Barnone' was an italian mafiosi name, and my ex-wife and a girlfriend were connected - then I read it came from Barn One down on the farm and decided to treat you like everyone else.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
I tried to figure out detail dimensions, but there was no way to find inner diameter without taking off the sproket. Went to the parts market this afternoon, after an hour's search I found a shop that promised they had a match, but first I had to take off the sproket. Found a repair shop near by and after a bit of Kunming lazy stares, started the job.
-1C today in Kunminghttp://hotimg23.fotki.com/a/113_106/186_8/P1060348.jpg
Now I know that because mechanics in China don't have a jack, everytime you go to a mechanic, you must buy a new kickstand! they tip over standing on the kickstand, and then silde the mik lcarton under.
http://hotimg23.fotki.com/a/113_106/186_8/P1060345.jpg
Took 5 hands to be able to take the wheel off. I't doesn't look very difficult but i but I don't have enough hands or tools. Here's what the stock sprocket looks like: http://hotimg23.fotki.com/a/113_106/186_8/P1060342.jpg
http://hotimg23.fotki.com/a/113_106/186_8/P1060343.jpg
Couldn't find a replacement: too small, or same gaint size, or recessed, or wrong bolt size.
Measurements below(flat both sides, no grove or dish, thickness 12.3):
http://hotimg23.fotki.com/a/113_106/186_8/jtr810.jpg
I'll email jtsprockets tomorrow for an equivelant and try to buy it locally on Taobao.
Edit: JTSPROCKETS replied saying they don't know much about Chinese bikes, given the dimensions I sent them, they gave me http://www.jtsprockets.com/61.0.html...rtnr=JTR810.50
Close enough but different size bolt holes. Hope they can find me a better match.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
That was very adventurous! Glad it went back on again, you don't mention the pain of that so you are either being stoic or it was OK!
I hope you feel it was worthwhile, even though you didn't get the sprocket first time.
Sounds to me that you are now understanding why people have two bikes and gather lots of tools ...

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Finally, got someone to help me out taobao'ing .. gave up on the local shops.. Since the wheel and sprocket are coming off, I might as well change the bearings. Any specific recommendations for the bearings?
How do you figure out what type of bearing to buy, other than relying on the goodwill of Taobao sellers?

How to replace a bearing:
http://www.youtube.com/watch?v=ArFC3xPHhGA
Looks a bit delicate, i'll make sure to be careful when the wrench monkeys start this job.
Haven't done this yet, but here's how to check if the bearing is shot:
STEP 1. Place the bike on a stand and check the wheels spin freely. For the rear wheel if the chain is tensioned and lubricated correctly, and the sprockets aren't worn in any way, using one hand to rest on the swingarm all there should be is a smooth rumble of chain over the sprocket teeth.
STEP 2. Grasp the top and bottom of the tyre from the side and try to rock the wheel backwards and forwards. Don't forget the bike should be steady on the stand and not moving around so if need be someone should hold it steady. Turn the wheel 90 degrees and do the same again and repeat until a full revolution.
STEP 3. What you are looking for is play in the bearings and this will be felt as a slight movement of the wheel or large movement if the bearings are seriously beyond use. There will maybe even be a clunking noise. You should check the wheel spindle isn't incorrectly tightened as this may lead to similar problems, but if it is okay it indicates one or more of the bearings is worn. As a rule of good practice it is sensible to replace all the bearings.
I'll just change them anyhow.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Nice video, Slabo. I like this guy's relatively sloppy DIY approach, and how he doesn't use surgical gloves with the grease.
But what makes me think that in all of China there is not a single mechanic (outside of a flash BMW or H-D shop) who has ever seen or even heard of a Tusk bearing remover or a slide hammer, much less possesses them? I'd love to be informed otherwise, but my guess is that the standard approach to bearing removal employs the Chinese national tool -- the hammer -- and maybe a blunt screwdriver pulled from under the mountain of dirty parts and tools and other detritus on the shop floor....
cheers

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Updates:: My girlfriend checked with a few taobao sellers, the few that advertise they're Shineray dealers, none had a sprocket that matches. So I went back to the parts market. I remembered seeing all sorts of dirt bikes. I thought they must be getting parts somewhere, maybe I just need to look more..
I stopped by this shop, as the laoban was not there last time I came.
http://hotimg23.fotki.com/a/113_106/...MAG0105439.jpg
I pointed to the sprocket and asked if I could find a smaller one.
Ahh, but you can't put too small. What do you want to use? ... 46? ... No, 46 too small, yes your choices are 46, 47, 48, 50, 52... you should use a 50
After some one sided arguement where I just repeat the few words I know to say, and they reply something in Chinese.. they agree that we should try anything. I show the diagram of the measurements I took last time I took the damn thing off..
Hmm, bla bla bla.. One of the helpers offers to join foreign monkey in search of the one, or many.. They look at the bike, argue something and give me a possible match. This goes on for sometime, and everytime I check with my trusty vernier caliper.. wrong wrong wrong..
I go back to the shop, laoban not there.. Now that I've seen how a wheel is taken off, I decide to take things into my own hands. I grab some tools, and a little while later, the wheel is off! Took the bolts off and as I'm struggling trying to take off the lockring, laoban shoes up. Off with the sprocket, back to the shops.. It turns out that the closest match is this:
http://hotimg23.fotki.com/a/113_106/...-113546-PM.jpg
That's the exact same one Humanbeing linked to in post #7 earlier in this thread. Only difference is it now costs 45, instead of 24rmb. Fine.
So no matching sprocket. And we have to machine this one to make it fit. Not too comfortable with the idea, but ok, I've exhausted all other possibilities now. a bit of this ::
http://i.imgur.com/M0BJs.jpg
and 30rmb later, I get::
http://i.imgur.com/XqfhI.jpg?1
Final result::
http://i.imgur.com/hzxvs.jpg?1
Now almost 6pm and I start hunting for a chain... Couldn't find a Chinese O-ring chain, so I got a KMC chain as Humanbeing advised. On my bike, the stock chain is a KMC O-ring (X, Y or one the varieties... now I've learned to tell by looking at it sideways.)
I was offered a D.I.D Oring, but I don't want to pay triple the price what I would normally pay out of China.
All in all, I don't really blame anyone at the market. They really went out of their way to help me, given my hopeless case. All the bikes I've seen there, none have a sprocket similar to mine. Maybe Shineray chose to make their own cheaper design? I mean if you compare it to others, it looks like a lot less machining time is put into it.
Here's the original sprocket::
http://i.imgur.com/74W7F.jpg

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
So how does the bike feel now?
Much smoother.. I didn't have a chance to check top speed yet, but I'm cruizing comfortably at ~5000 rmp. It's been windy last couple of days, so I still can't tell for sure.
But as soon as I left the parts market, I hear a ticking noise I haven't heard before. Only when I accelerate, and only for a few moments. When I got home, at closer inspection I see that the chain is hitting the upper chain gaurd. I think it's because I changed to smaller rear sprocket. How to fix this?
http://hotimg23.fotki.com/a/113_106/186_10/P1060373.jpg
Another problem, I think the chain is wider than the sprocket! It moves sideways on the sprocket parallel to the axel. Maybe better find a better sprocket in GZ market? Is this normal? I don't know because I never checked on the stock chain.
Yet another problem is the front sprocket. Same as before, 17 tooth. It moves about 2mm about it's axis if I try to move it. Is this supposed to happen?
http://hotimg23.fotki.com/a/113_106/186_10/SNV37428.jpg
Another issue, not sure how critical this is. There is about 1mm space between the lockring (not sure what to call it) and the sprocket. This is because we had to machine the spocket. Is this critical?
http://hotimg23.fotki.com/a/113_106/186_10/SNV37431.jpg
As you see, I'm still using the old chain. First time I bought the wrong length chain. I'll buy a chain tool sometime tomorrow change it.
After all of this, I'm thinking to buy a new rear wheel, with a more common sprocket. But sometimes I'm not sure it's worth putting money into this bike.. After the last upgrade, lets call it an upgrade for now, I feel the suspension is really bad. Bike keeps bouncing slightly after acceleration, or changing direction. Not sure I want to think of doing anything about that.
I might be in GZ around Chinese Newyear's, maybe I can get better parts there.
Note for santa, My xmas wish list:: boots suitable for touring/daily commute, weather proof riding suit that doesn't make me look like an astronaut, chain, sprocket, mini tool bag, some pen looking tire pressure gauge...

Maybe you can slot the mounting holes of the chain guard to move its position.

A small amount of sideways movement is normal, but I'm positive you're chain is WAY out of specification. Impossible that a KMC 428 chain is still in spec after 9000 kilometers.

Normal for this kind of output shaft and the way the sprocket mounts. My Galaxy is the same.

Noooo. All these components wear together. A toasted chain can chow through new sprockets pretty quickly. If you don't have a chain tool, just find any old workshop with a grinding wheel. Grind the pin off, and then use a punch to drive the link pin out. Put your chain adjuster all the way forward before measuring the chain.

Finding a new wheel with the right dimensions would probably be expensive and very difficult. You need to have the correct spacing to keep the rear brake and sprockets lined up.

Sounds like the rear shocks are only using spring tension instead of hydraulic pressure.
Doors open at my place during CNY if you need a place. The GZ market has a lot of stuff on your Santa list at reasonable prices.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Don't let it get you down Naim! I would have given up before now but you are getting there. You can always refit the old sprocket ... :icon10: Try and get the rear shock looked at too, try the same guys, they will get used to the weird foreigner then. Take a pack of Dunhill cigarettes or something with you as felix and others suggest in other threads. You will end up with a 'bike you can travel across China on. I would have liked a Long March myself, good looking machine.
Give the 'bike a while with that sprocket and see if it is smoother through the gears and has a bit more top end. I may have misled you when I said don't need to change the chain in my own thread, as China V says with these cheap 428s you are likely to get wear.
You can only keep doing this stuff and learning and one you day you either feel it was worth the effort of persevering on the adventure or you save up for a Mercedes and maybe sell your soul to do that!
You are doing it pretty much on your own in a strange land with a quite rare model of 'bike to setup. Doing well. Anyway, have a great CNY and I hope it all works out for you.

Re: Sprockets and chain for my Shineray XY200GY-7, the vibrator
Everyone thanks a lot for walking me through this, I've learned a lot.
First time I changed the sprocket, I bought the wrong length chain. So I had to put back the old one to be able to ride back home. Changed the chain today. Got my hands dirty, typing this with dirty greasy paws now. Really difficult to clean this shit.. I used as many links on the new chain as the old, but even after pushing the real axle to most forward position, I think there is still not enough chain slack. 2cm enough? But I found out putting back links is much harder than taking them off. Especially with the cheap tool I had.
ChinaV, the space I'm talking about::
http://hotimg23.fotki.com/a/220_163/35_203/SNV37431.jpg
The c-clip in question is this:

You need a tool like this to take it off
http://hotimg23.fotki.com/a/220_163/...pliers-i-L.jpg
This happened because the sprocket was machined.

Use girlfriend's 洗手膏 before dirty work, keeps much grease off. Nothing wrong with gloves either!
That wire still looks a bit close in the front sprocket picture.
The rear sprocket bolts hold your sprocket tight to the hub, it looks like therefore the gap is not so important as it cannot move, but to be sure you could look for or make a shim. On mine the gap was critical as the sprocket bolts floated in rubber bushes and the slack had to be taken up so I used washers behind them - but yours is a direct bolt.
The chain looks OK to me. I don't understand how it can be so tight when the new sprocket is smaller diameter! I was stupid enough to feed the chain the wrong way through the guide which is different on the Kinlon so mine was all wrong, but I couldn't ride it like that, you have ridden yours so it must be OK?
2cm is a bit tight for a dirt bike chain but OK I reckon, on mine I like 2 cm up and 2 cm down but it will probably slacken off a bit.
You have what looks like a large split pin through the axle? Always replace them.
The knobbies are a bit harsh for tarmac and smooth roads, some of the vibration you got will have come from them. If you don't go off-road then the motard style tyres will be a smoother ride of course and still have grip on gravel.

The wire is separated from the chain by the cover case, no problem there. An image from the first post shows how it was crimped during factory installation, and that caused the gear indicator to play up at times. That's fixed, the dealer replaced the cable with one off a new bike in his shop, now it's the other guy's problem. Bike already sold by the way :D

I made the chain as long as the chain that was on before, which was the old chain, only made shorted because i was using the smaller sprocket. As I said in the previous post, It was late, and I the chain I bought was too short, so we had to use the older chain again. For that, we had to take off a few links. For two days only, total riding 20km. My mistake was using as many links on the new chain as the old(now shortened), but the older chain was actually a bit stretched.

I'll definitely get different tires next time.

- in the rear wheel photo it looked like a split pin through axle, but I zoomed it and saw it was not, sorry.
