Anyhow, please PM me if the download doesn't work, then I can email it or send it by skype.

While trying to make my clutch and brake lever point it bit more downwards, because I don't like the levers to be almost at the same horizontal position as the handlebars.

Due to the electrical parts having only a limited narrow space at the back for the levers to be able to be fully pulled back towards the handlebars, ofcourse I thought then move them as well! But as mentioned by someone (probably ChinaV) about another bike, these parts are fixed by a small hole drilled into the handlebar.
So I ended up moving the whole handlebar forward to get the prefered angle between handlebar and levers. I hope this won't cause any back problems after a long ride. We'll see!

Pfaelzer,
Does the Tourfella box goes with metal bracket? The one they send regarding taobao is that I can't understand Japanese characters. Can you please advise me regarding my question.
Hi,
been away for a while. Business... Finally I have completed and updated the front spring modification post here:
PROGRESSIVE FRONT SPRING MODIFICATION
I will have some days off over the eastern holidays :riding: and plan to make a 4 days ride in Fujian province together with my better half. After that I can give more feedback on this modification and maybe fine-tune the front if necessary.
Cheers,
AW.

ALLUMINUM PANNIERS
If you need the direct contact to the manufacturer, please PM me. The boxes don't come cheap and considering also shipping costs you will be up to something. If you can't get through to the manufacturer, let me know your questions and I'll have the details checked out for you.
Cheers,

I do not clearly understand the problem you are having. pictures might help...
I found raising the handle bar helped quite a bit in seating position. you might consider this. However, my bike is not the "latest version". Raising the bar, madethe clutch cable a bit tight. I am trying to get a longer cable from Jialing now.

Welcome back AW! It is great to see what you've done with the front springs - thanks for sharing!Quote:

I've asked it to design & engineer a dial-in, adjustable front suspension system that is slightly more robust, easily swapped over, and still remains within a typical consumer budget. I've also asked the company to review the stock fork seals, as I've seen a couple of JH600s that have done extended Xinjiang trips on washboard - the seals started to leak after a few thousand kms. We'll see what it comes up with, but I am guessing it won't be immediate.
I haven't used my JH600 under heavy load, so the rear shock hasn't been an issue for me. If I was loading the bike, I'd consider going with TA's option of an adjustable unit. Nor am I racing the JH600, nor doing hard off-roading for extended periods. I have had, however, my JH600 touching the pegs at speed in corners and have not felt any concern with the suspension off-tracking or overly compressing from inertia load.
Stiffening up the rear end might result in the 99% of my casual riding to be a little more jarring, and my own personal preference is for smoothness. From my own experience, my only suspension issue appears that the front is a bit too prone to dive when braking, but that could be partially attributable to my size / position / style / etc. Eh ... I've just adjusted the way I ride the JH600.
I'm still very happy with the bike for what it is. However, I may change the brand emblems to "BMW" to avoid having to listen to "really? you bought a Chinese bike? why?"
Enjoy your upcoming ride!
Cheers

Wow, Richard,
Cool plan you got here with the front fork. Can't imagine that this can be done in a "developed" country at a "typical consumer budget". Really looking forward to see, what comes out of this. I had a small lunch-time ride today again, much on unpaved roads and I must say, that simply changing the springs (90 Euros) and the oil made a big, big difference. I am almost at a point of total satisfaction, almost. TA's hydraulic spring-tensioner would make things much more smooth, very sexy. Instead I have to fiddle with tools all the time to play with the spring-load. Another thing, which I need to check - maybe someone knows here - is: When the front get's "aired", decompressed suddenly, then the front-shocks hit a kind of end point and it makes a quit unpleasant sound - like metal hits metal. I understand some models have rubber dampers inside to avoid that...
About the rear shock - I fully agree to what you are saying, nothing really wrong with the original part. Having said that, I changed to a custom Wilbers shock on my R1150GSA after running down the original one with permanently riding fully loaded, and it made a huge difference in the way, how the bike feels. Even solo. It's not really about stiffening up but more about a solid feel and faster response. Same thing on the JH600. Come to Fuzhou and try it out...
After all, looking at the performance, it is still a China-bike, far from anything close to a BMW, even though with big fun factor. I really like the JH600 too and we should not be shy to show it. A BMW logo on it would be kinda weird.
Hope you will post news on your modified "front-end" soon (ChinaV, I know what you are thinking now :naughty: ...but I mean the front suspension of the JH600).
Cheers,
AW.
Yeah, I'm really eager to get my dirty little paws on those springs - alas, Franki has disappeared & I think TA would ship me his wife before he'd part with his unmounted springs.Quote:

I suspect that I won't get any news for several months - my objective was to reduce the dive, and also have it adjustable. I'm lucky inasmuch as it is a relative that owns a group of performance mod shops back home, albeit primarily for racing bikes (those things I love to hate!). He'll set me straight, I think, for someone within a consumer budget (i.e., it doesn't have to be perfect for making 200 kph corners).Quote:

Might be helpful to use a thicker oil and a higher pre-loand (extended spacer) to reduce travel and response for your road-riding focused purpose. Changing the oil should be definitely a great idea as you can see in my post about that.
PM me for the springs if you like.
Cheers,
AW.
Great find Barry, thanks. Motul is a trustworthy brand, I think, and seems to be widely available in China. I'm going to go for the manly stuff and order 15W. If that doesn't do it for me, then I'll definitely be taking up AW on his very generous offer (I have first dibs, folks!). Hmmm, i wonder if heavier oil would be more prone to blow the seals?
No idea about temp on fork performance.
Most manufacturers recommend changing the fork oil about every two years, or 20K miles. From AW's informative notation about discolored oil in one fork, maybe the JH600's original oil is not very good and the first change should be sooner.
While changing oil wouldn't it be a good moment to replace the seals as well?Quote:

I have no idea what those seals cost, but I guess they are quite cheap so I thought "prevention is better than cure"!
Pfaelzer hi again, how are you?
can you tell me where I can buy oil filters, air filters, oil ... all for my engine :scooter:
you know a reputable dealer (cheap) on line? :icon10:
thank you very much. :thumbsup::thumbsup:
PFAELZER!! I need some help!!
Iīm looking for a clutch, mine is broken, is blown :eekers:
Dear Pfaelzer, Lao Jia Huo, Barry and other JH600 devotees,
I'm definitely up for this mod. I'm in much the same boat as LJH with respect to fork dive when braking, and I don't like it at all. (I'm thinking this could well have been a factor in my getoff last summer in Kunming, though the primary error surely was human.)
As for which fork oil to choose or whether to swap seals, damn, I'm a total naif on both counts, but I really need to do something to firm up my front end performance. Progressive springs with a more viscous oil would seem the right approach for me. But how do you even know what springs to buy? Don't worry, LJH, I'm happy to source them in the US if need be....
cheers
Hey Mr Euph et al ...
I might be suffering from wishful thinking & delusions believing that heavier fork oil might solve our common concerns, but I thought I'd try it out first. From what I've read online (the great authoritative source!), heavier fork oil might do the trick. But, in my case, it also seems that the forks are just a bit too dive-prone for fork oil to be the silver bullet.
It is quite possible that your getoff was largely caused by a diving front end, as jittery physics come into play when that nose goes down, especially on a wet road surface.
As for the springs, I feel kinda bad asking AW to carry back springs. Maybe all of us JH600 folks should collectively reimburse AW for carrying a crate of springs back? AW says he's noticed a positive difference ... good enough endorsement for me!
I'm game to try a variety of options on the forks because aside from the nose dive, I'm pretty happy with everything else about the JH600.

It somehow is always a compromise however. You want it firm on-road, but god travel off-road. To me, this choice fits well and I can share the details.
As to the oil: CAREFUL! If you go up too much, you will see your front-end less responsive and "jump" over bumps. I have now 7.5, but I think of reducing it to 5.
Cheers and have fun,
AW.
artop,
I don't know any dealer or online shop for Jianling parts. I get everything from Jialing directly. Guess I might get you a clutch.
PM me if you need my help here.

Typical situation: A cyclist enters the main road from a side street. He just does not turn his head, because he is whatever, too busy with things going on in front of him or just too lazy. This guy fully relies on somebody blowing the horn if things could get tight. Only then would he slow down or stay closer to the side of the road. The better he hears you, the more he will react. Right or wrong - that's how it works on China Roads.
With this air-horn - thanks again, chinabiker - I could even get attention from truck drivers on my last trip. Here some pictures and ideas of how to fit it nicely hidden on a JH600.
That's the horn:
http://pfaelzer.smugmug.com/Motorcyc...505_fam-XL.jpg
My team designe a nice little bracket so that I can mount the horn tight to the bike. It should not fall off on rough roads (and it didn't happen here).

Horn with bracket and some tape to fit it in the curved plastic of the bike.
http://pfaelzer.smugmug.com/Motorcyc...dsc01192-L.jpg
It was not easy to find a good location and we ended up there. It is tight, but with some try and error it fits in well, still a good gap to the front fork.
http://pfaelzer.smugmug.com/Motorcyc...dsc01251-L.jpg
When we did that modification, I wans't sure, how I would use the horn, so I upgraded also the original "beeper" with a dual horn and added a switch so I could toggle between the two. Lot's of wiring, I think about removing the switch and the twin horns again, because the air-horn does the job well.

This picture was taken after the ride on last weekend.

...back to overview.
Is that horn sourced in China?
I'm interested in this question too!Quote:
