brand new second hand JH600

NOW FOR SALE 12,000 RMB




Hey,

I just bought myself a 2008 JH600 and she needs a bit of work. The guy i bought it from was only using it to ride to the bar and back and it only has 7700 kms on the clock! He dropped the bike and injured himself so decided to sell and look for a 250. Anyway, the bike's in good condition mechanically but I'm thinking about some mods after reading Pfaelzer's amazing thread!

Here are some pics...

here you can see some of the accident damage

more damage

He used it to ride to the bar? No wonder he crashed it :O

The accident damage doesn't seem too bad, a bit of epoxy and taobaoing should take care of it.

There are a few other areas of greater concern where some advice would be greatly appreciated...

#1 forks
I think they need some stiffening up. I cant really afford to invest in progressive springs at the moment but it seems that a w15 oil and maybe longer spacers could be the way to go.


#2 ECU
I rode the 250 kms back to Shenzhen and it cut out once, doing 140 just before a corner! Motokai recommended a spark plug change which I will do, but should I change the ECU and are there any other faults with the 2008 model in this area?

#3 Panniers
I really like the tourfella setup that motokai and others have but are there any cheaper options out there?

#4 Tool box
Does anyone know of any manufacturers who can make a tool box as seen in Pfaelzer's thread?

#5 Exhaust
Milton seemed to have a way of modifying the stock exhaust, does anyone know how this affects performance? What other cans are available in China?

Congratulations, Tom, on your new JH. The black is the right color.

Euphonius and I did change the fluid in the front forks to stiffen it up. I just followed the leadership of Mr. E, with the supposedly better performance, which to be honest did not make much difference to me. But Mr. E swears by it. Ask him for details.

As far as the ECU stalling problem goes, the ECU version on Motokai's and mine (2009 I believe) is the one having the most severe symptom. Older version like Mr. E's is not as affected. So you need to make your own judgement on it. Again, check with Mr. E as well.

For the exhaust, I am still having my stock one. When I first got it, it backfired like crazy, which seems to have toned down a bit now. However, nothing can't be solved in this department with a pair of ear plugs. Motokai's Laser ProDuro does offer a lighter weight and purportedly better performance.

Cheers!

Dear Tom,

Congrats on your very excellent score!

As Milton noted, changing to a higher viscosity fork oil made a substantial difference for me, all but eliminating what had been a pretty serious problem of fork dive. I try to balance my braking front and rear, but certainly favor the front brake and felt the diving was unsafe as well as annoying. At 90kg, I've got a few pounds on Milton, which could explain the difference to some degree. If I'm not misremembering, Milton may also have had his forks rebuilt after a getoff two years ago down in Zhejiang or Fujian. So we may be comparing substantially different equipment. I did not swap out the springs for progressives, or change the seals. If I were you I'd definitely tinker with the fork oil.

As for the ECU, I've indeed suffered far less stalling than the dangerously unacceptable levels that Milton, Motokai or Lao Jia Huo did, though my bike has not been immune altogether. And when it does stall, it's typically when you least want to stall and lose power -- like downthrottling into a turn. Before doing the ECU upgrade, Motokai became adept at using the electric starter to restart; I tend to drop a gear and use the clutch, but this is not always the safest response if, again, you are entering a turn and don't want to chirp your rear tire and lose traction. I actually purchased the entire ECU upgrade kit -- third-generation Bosch ECU and the slightly modified wiring harness -- but I've yet to install it, thinking, why tamper with success. For the time being, unless the stalling worsens, the kit stays in my apartment.

The bike is not very tolerant of shitty fuel, especially ethanol blends. The Jialing will purr at 140kph for hours, but mine had one terrible spate of high speed stalls and sputters on the expressway in Shandong that wasn't resolved until that tank of gas passed. So I wonder if that's what you experienced during your inaugural ride at speed?

Yes, I've also got the ProDuro can, which sets off car alarms when used properly and delivers very pleasing backfire almost on command. Nothing wrong with the stock muffler, especially if you prefer a quieter ride. I don't think any of us has compared output on a dyno, so any tailpipe-related performance increases are probably apocryphal. The ProDuro is definitely lighter -- maybe half the weight of the stocker -- and there's no doubt our bikes do SOUND more powerful...

Take a good look at your frame to be sure the previous owner didn't bequeath you any cracks. For a bike of its weight, some of the frame members are a bit underwhelming, especially the main frame under the seat and rear rack.

The only alternative to Du Rui's very nice Tourfella racks that I know of are those from Jialing, which are offered as an upgrade on the current JH600A model. They look OK, but the quality of the metal and machining doesn't come close to the TFs. And Du won't sell you the racks without the TF panniers....

You'll definitely want some sturdy hand guards unless you plan to always carry spare levers. If you are in the habit of dropping your bikes, lay in a few extra front turn signals (only 40 yuan or so a pop, from former Jialing marketing guy Tang Wei 唐炜 in Chongqing). The JH600 has handled all of my getoffs with aplomb (better than my clavicle and fibula). She's still too heavy at just under 200kg and not overpowering, so you'll NEVER lift your front wheel. But she's a fun ride, and very good for much of China.

Cheers

One more thing: I'm guessing you're running the original Chenghsin tires. You might want to consider some better rubber, though this will raise one of the most vexing problems for owners of bigger displacement bikes: sourcing quality tires in our sizes. Most of us JH600 riders handcarry tires back from the US or Europe, which is particularly ironic in my case since I'm running lovely and rugged Kenda 761s that are made just across the strait in Ta*wan.

A bunch of us actually tried importing a batch directly from the factory to Kenda's suburban Shanghai plant, calling them "samples," but the shipment was stopped by Chinese customs because they are not registered by the Ministry of Transport (or whoever) for use in the mainland. Demand is so minuscule in the mainland that Kenda has no incentive to do what it takes to get these tires registered here.

You may have better access due to proximity to Hong Kong. Our tire size -- 130/80-17 4P 65H and 100/90-19 4P 57H -- is common to the Suzuki DR650, Yamaha XTZ600 Tenere, Aprilia Pegaso 650 (a blatant copy of the JH600!) and other popular bikes.

cheers!

thanks Milton and Euphonius! I think I'll move ahead with the fork oil and leave everything else for now. I've got a week off coming up so I'll do a few thousand kms around Guangdong and properly suss out the bike. It's great news that I may get away without the ecu mod, I think the money I save will go into registration which chinav reckons could be very tricky. fingers crossed eh!

Congrats on your purchase!

Only to/from the bar? Five years old, 7,700 kms? OK, that's about 1,500 kms/year. Assuming 20 kms round trip to the bar, that is 75 trips a year. As Spencer says, no wonder he crashed it ... surprisingly only once!

Just joking - looks good - correct color, too!

on a totally unrelated matter :lol8:

What's that front tire you've got on the bike? That definitely ain't no original Chengshin! Regarding tires, Motokai and I got Bridgestone Battlewings! I really love 'm and they can be bought from taobao for just below 1700 RMB a set.

Black side cover is less than 300 RMB from taobao. Don't think it's worth it to fix and repaint the current side cover. Unless you only plan to epoxy and then leave it like that!

As for the fork, I've put in 10W oil and it's way too stiff. Will try to reduce the amount of oil when I've got time and see how that works out.

ECU, leave it as it is if the stalling ain't too severe. Even if you do the upgrade, you still won't be stall free as far as I know.

@ Euphonius, Du Rui will do another pair of racks for someone who already both a set of TF's from him I hope?

Hey Barry, I'm not sure about the tyres, the guy had just put a new set on but I'm not sure what they are. I'm gonna head out to my shed/mancave next week and get started on the bike. if I can pop the plastics back into place I'll be content with reinforcing the break with epoxy, if not then I'll replace it.

I was gonna go with a w15 fork oil but it sounds like that could be too thick. I think it'll be something I'll need to play about with....

cheers!

Good evening Gentlemen,

Having considered long and hard about hard luggage, i think Im going to go with my soft panniers and a top box. Can anyone help me out with sourcing a Jialing rack? The hard luggage people wont sell the rack without the boxes (which is silly as I may wish to upgrade in the future!) and I cant find any jialing shops in the pearl river delta.

I also need a new passenger footpeg, can anyone point me inthe right direction? Motokai has told me about his super convenient JL dealership in Shanghai but there doesn't seem to be anything like that here. In an ideal world I'd have a guy who has connections with the factory.

Any help would be greatly appreciated!

Also....:naughty:

I loved the look of Pfaelzer's tool box that fitted low down at the front of the bike and would like to fit a pir of crash bars to my 2008 model. Has anyone got a likely shop in mind?

Thanks in advance!

PM on the way.....
This Taobao shop had a broad selection of JH600 parts in the past: http://chn-mcu.taobao.com and dealing with Shanghai JL JH600 Service Centre and CJ shop owned and operated by Xiao Fan: http://www.mychinamoto.com/forums/sh...hai-Shop-(Fan)
Do let me know if you need Xiao Fan's direct contact details and shall PM them.

Surely there must be JL dealer / service centre in Guangdong province.....

thanks to TB and Euphonius,

I may have located a shop in a small town called zengcheng near guangzhou but no idea if they can help with JH600 parts. will visit next week and check it out, GZ and SZ seem to have nothing...

I have had miserable luck with punctures in the past and would like to convert my wheels to take tubeless tyres. it seems possible to DIY the rims with sealant, does anyone have any experience with this or converting rims in general?

thanks!

I just had a wander around GZ bike market and found a seriously pikey kit to convert spoked wheels to take tubeless tyres. It comes with a tube that fits tight down in the rim to cover the spoke heads, some weird glue stuff and a baggie of rubber shavings! I'd give it about a 15% chance of working as it was only 15 quai :lol8:

http://www.michelin.co.uk/motorcycle...lin-bib-mousse ,not sure they provide JL JH600 sizes......

I'd suggest you stay with tubes, unless you also change the wheels. I'm not sure you're going to have a positive seal along the edges of the stock rims (it is not just the spoke nipples to be concerned about).

Stay away from 99% of the tire sealants, foams, etc. They are not a good idea. A cousin back home has a chain of tire shops and he's shown me what happens to wheels and tires from that stuff - most shops now refuse to deal with tires/wheels that have that crap installed. It makes a mess of their workspace & machines.

There is one product, however, that gets two thumbs up from many adv riders. As I'm in negotiations for Asia's distributorship, I'm not going to shamelessly plug it (pun intended). But you can easily find lots of discussion about it on western forums. Or you can PM me. However, it ain't cheap.

HD Shanghai + Beijing dealerships offering a tire sealant "service" now, bit pricey: http://www.hoghd.cn/viewthread.php?t...extra=page%3D1

Slime Tire Sealant works great for me (car/bike) and washes off with water.... http://www.slime.com

Here's a pic of the tubeless kit I just bought

Im gonna give it a go, will keep you posted.

I haven't had any luck with racks as no-one seems to make them for 2008 models anymore. Im probably gonna ask my welder to knock something up.

Hi Tom,

Just caught your post. I have a brand new set of Jialing racks, which was incorrectly shipped to me a while ago (long story!). They are still unwrapped. I am not even sure if they are a complete set. You can have them if they fit the model year of your bike.

BTW, I am still have the hand-me-down racks from Motokai, over which I throw my GDW waterproof soft panniers for longer trips. That, along with a top box, works great for me.

Milton

A thousand thank yous Milton, you are da man!! :clap:

i just spent the day working on the bike and as always it wasn't a total success.

First off I built a phone mount


Attachment 10396
crude but hopefully effective

Attachment 10397
I had it welded and the paint is drying now. Will hopefully finish it tomorrow

Next on the list was the crash damaged front fairing


Attachment 10398
It popped back into place with some gentle persuasion - Im gonna try and find some t cut


Attachment 10399
Then I epoxied the shit out of the inside :naughty:

The bike had leaked a little oil overnight and the drain pliug felt like it had possibly been overtightened. We tightened it as much as we dared and then wedged a piece of ply in between the nut and the bash plate to hopefully stop it falling out completely.

Attachment 10400

Any advice here would be fantastic!

The original master cylinder had a smashed view window so I replaced it with an old yingang one I had lying around. I was amazed to find that the mirrors were left hand threaded! Anyone know why?


Attachment 10401

Attachment 10402

I followed Motokai's advice and epoxied the chain guide in place

Attachment 10403
Im thinking about disabling the side stand cut off switch. Is that recommended? It has three wires so i wasnt sure how to go about it...

Attachment 10404

The can isn't welded to the pipe and you can actually move it quite a bit. Is that normal and should I get it welded?
