Shineray / XinYuan X5 review

I've noticed before that the bike feels wobbly above 115km/h. It feels really scary so I actually am afraid to ride it above that speed. I thought it might be unbalanced wheel or wheels, so since I will be changing tyres soon, I figured I will check then. I rarely ride above 100km/h so I wasn't bothered much.

Today I've noticed that the bike wobbles more (or it's just my imagination). All the bikes I've ridden before were very stable. You know, when you shake the steering bar at around 80-90 it will give you a wobble and you feel that it pulls you out of that wobble. Shineray, on the other hand feels like it wants to wobble more and I need to intervene. It's really strange.
Thought it might be soft suspension so I wanted to adjust and the front feels like there is no difference whatsoever on softest and hardest setting. Also the adjustment nut is significantly easier to turn on the left side. Rear shock seems OK.

Anybody had a problem like this? Or tried to adjust the forks?

Check Head Bearing and wheel spokes tension and tyre pressure?

I had ridden the X5 up the 130kmph and had no notice of what you describe.
Follow the Prince's advise.
Additionally check how easy your front wheel is rolling to make sure there is no bearing defect.
I ran the original Kenda tires without problems.
BTW: the forkchas adjustment possibility also at its lower ends.
(Already considered?)

I played with that fork adjustment today, turns out it take few hundred meters to kick in.....
Once you turn the adjustment screw (14 clicks) nothing really happens to the suspension. After riding for a while it gets harder or softer respectively to your adjustment but not by much. Actually the difference is very slight.
Also, they try to trick you...haha there are big letters "S" (I thought for soft) and "F" (I thought for firm). S is clockwise and makes the suspension harder and F is anticlockwise and make the suspension softer.....go figure

Anyways, on the hardest possible setting the bike feels a bit more stable but not as it should. I will inspect and let you guys know

I tried to change the tyres today so I had a chance to inspect the bike a bit. The steering bearing seems fine, spoke tension also ok, wheels spin smooth. Im guessing its the balance but they dont have a way to check it there in the shop.

Eventually I didnt change the tyres cos the new ones are too big. I got myself Metzeler Karoo 3 140/80-18. Earlier I went up 2teeth at the rear which pushed the wheel forward a bit. This and a beefier tread resulted in wrong setup (chain too short). Also the tyre rubs on the chain guard so I will have to trim it a bit. Anyway, I have to buy a new chain so I also decided to change the rear sprocket to even bigger one, 44teeth

Hi Modron
You can static balance you front wheel very easy.

Yeah, I know its easy yet I dont have the right tools. I tried to use a pit bike stand but no luck so I decided to leave it for now. I did place a random amount of weight opposite a rim lock but had no chance to ride it yet. Will see how it goes

Bike wobbles much less now. Like I said I placed some weights on the rim and I also tightened the head bearing (although it didnt seem loose). Here is few pics from last ride

U have a Karoo3 on the X5?

Good eye! Indeed
They are more versatile than the stock Kendas

Its only May and the weather is boiling. Today it was around 30 C and my lil X5 is got hot. On an open road its ok but in the mountains at a slower pace it struggles, loses quite a bit of power and cooks my calves.
Im thinking of putting an oil cooler. The easiest place to connect the cooler is as on pictures (frame-->oil cooler-->cylinder head). Im thinking if it might slow the oil circulation. Adding some thin pipes and fins just before the cylinder might interfere with it getting the right amount of oil....or Im just imagining this? It just seems logical but then again I might be completely wrong ;)
I remember seeing a cooler on Princes YBR125 in that same spot.....his engine blew up hahan (prolly different reason tho)

On the pic no 1 and 2 are points between I want to add the cooler. No 3 is what I initially thought was a reminder of the first generation's oil cooler but in fact its turning circle limiter ;)

Didn't the very first batch of the X5 come with an oil cooler originally? If I remember correctly it did....

Some other options:

- give your radiator a proper cleaning, make sure its not filled up with mud, sand, dust, etc
- use radiator cleaner to flush the cooling system
- find a better coolant
- make sure your engine oil is at the right capacity
- use different engine oil, more suitable for hot weather conditions

Big bore kit too much WOT was the reason for the demise of the YBR 125 cc but did get over 30.000 km until that time.
Fitted a Lifan 250cc 6 speed box runs like a dream.

Yeah, the first models had oil coolers. Later they have decided that they can save some money by taking them off i guess. The engine is completely air cooled so there is nothing to do apart from changing oil which Ill do this week. I still have 10w40, will go for 15w50 and will see.

Ive found that this tube is not a proper oil tube. Oil is not pumped there so I have to somehow fit the radiator in the place marked with red on the picture.
I dont have a great idea how to do it though. Maybe cut the metal pipes and pull a new hose over them and hold it in place with some braces

Fit an oil temperature gauge first and see how hot the oil is getting, much easier to do and even later you can fit an oil cooler if needed you then will know how much difference it makes to the oil temperature ???

You could even fit an oil temperature dip stick yes there is such an item seen them on Taobao.

I guess its a good reference point. Ill get myself one of them thermometers for cooking. Had one before but got misplaced

That will work try and get a digital type as it will read the temperature very quick.
Check online for recommended oil temperature and you are good to go

You had swing arm break? Second gear bust out? All withingfurst year n 6-9000km?
1 guy here has and he blames the bike not his riding style

I think it would be way more likely to break the frame than the swingarm. I would say the swingarm is actually one of the nicest parts on this bike, it's bearings on the other hand....

No problems so far.
Today I will change fork oil to a heavier one cos the front is a bit too soft

So I have discovered that my fuel tap isnt working the hard way yesterday.....
Got a front puncture and obviously there is no center stand so the easiest option was to lay the bike on a side and work on the wheel. The fuel started dripping through the carb breather hose so i close that off. Then it started leaking a substantial amount through the airbox and air filter. Not only it was dangerous but also wouldnt let me fix my flat.
Fortunately I was with my mate so he helped me balance the bike on some rocks

Is this faulty tap a reason for missing fuel? I didnt ride my bike for about 2-3months in the summer and when I finally did I have noticed that the consumption was about 40% higher. I think the petrol might have just evaporated through the carb

That doesn't make sense because the floats and needle should stop the passing of fuel. I would look at the petcock, floats, & needle. replacing all 3 should be less than 100 RMB. Shitty China gas could have caused problems.

I would be more worried about the gas that didn't come out of the airbox and headed into your cylinder via the intake valves.

Well, after the whole thing the bike starter and ran fine. I will replace the petcock and check the float and needle. And will replace the oil as it prolly has fuel in it, although I just did that 500km ago :sad:

Does anyone know whether the front sprocket (most likely according to taobao) of Honda Xr400 will fit the X5?

More importantly
Will xr400 wheel bearings fit the X5?

Im going to Europe soon and could buy some parts. Sprocket I can measure but the bearings require a bit more precision

My advice would take the bits of the X5 with you back to the EU and then match them up.

I thought about it but wanted to avoid taking the bearings out.
If I cant confirm the size I prolly will though

10 mins job and you will make sure you get the correct one.
Also, most good makes are marked with the inner and outer size in mm.?

Just take the wheels out. Remove the dust cover ring and read the bearing number and brand on the out bearing ring. The numbers are something like 6605 ...
Then put dust cover ring in assemble wheel. Story done.
Anyway I would not carry that stuff from Europe. Bearings you can find from industry supplier in China -> FAG, NSK, etc.
I bought all engine and wheel bearings for my X2 in good quality in China.

Oh, ... And ifvyiu can only find sealed bearing (normally with Z at the end) just use a little screwdriver and remove the seal ring gently. Then you have a normal bearing :-)

yup, easiest way to check bearings - see marking on bearing, exactly as Shuben said.

for sprockets I could advise to check this link and see whether Honda XR400 sprockets size match dimensions of Shineray's
http://www.jtsprockets.com/catalogue/model/877/

maybe you even don't need to take off X5 sprocket, just check some links on taobao, where seller show sprocket dimensions and then compare them to dimensions from link above.
