    There's a non return valve behind the oil filter. Maybe it doesn't close fully (it's just a plastic ball and spring) but I wouldn't worry about it. Putting a new pressure switch in won't hurt.
    If you cam retainer isn't bolted down properly (i mean really loose) you might get this as well but I'm assuming there are no untoward noises and the bikes runs as well as any time.

    Well the issue with coil is usually not the coil but loose/burn contact cap at spark plug side.. what are the chances used one will be fine?

    At @hansi I just cleaned it and jammed a strip of beer can in the hurry.. 18k later it's still there working fine from what I can tell.

    Thanks DG that’s reassuring. I’ll check the NRV next change and put a new switch in, The bike runs just fine and there are no noises.

    I did the same after finding out the contact clip had rusted away a few year back.
    Use a few strands of copper wire.

    Operation "kick the can farther down the road was a total and complete success."

    Welded on a new front sprocket yet again. The last one made it 6,000ish miles and was still in decent shape but the rear sprocket and chain were completely shot... Went ahead and replaced the whole kit at one time

    Took a while to find a proper welder here in Istanbul buuuut this guy who specializes in CV joints and spline shafts was the boss with the sauce

    After grinding off the old front sprocket that was welded on previously with a rotary file and using a bearing puller there was not much shaft left that still had teeth... We went ahead and machined down the new 15 tooth front sprocket to match the shaft length for a better weld using a lathe and I can report back this is some hard metal brought to you from France hahaha

    Using a jig apparatus we fabricated the front sprocket was welded on and is about as straight and perfect as it can be in an imperfect world hahaha I don't know if I'll be able to weld on another front sprocket after this one wears out in the next 10 or 15,000 miles.... Fingers crossed

    I installed a 15-49 sprocket ratio this time compared to the 14-47 I was running for the last 6,000 miles... 15-49 is exactly where I wanted to be. Just a little bit less buzzy on the highway but still plenty of braaaaaaaaaaap for the dirt.

    Let's hope this mighty unicorn can stay on the trail for another few years

    PS- I got my front and rear sprocket ordered from:
    https://scheffelmeier-metall.de/BMW...r-sprocket-steel-49-teeth-BMW-G650-X::55.html

    Looks like they are just French FE sprockets repurposed and dropped shipped... Not much of a price difference buying from this dude but shipping was one day to my friend in Germany

    It was going to cost $220 only to ship the parts to Turkey so my German buddy shipped these bad boys to Bulgaria and my Romanian lady friend went across the border from Turkey to pick them up for me since I'm not able to cross into the EU as an American at the moment

    Folks, anyone installed Scotts stabilizer recently? Using the search button, there have been just a few talks about it; only one post with pictures. I can assume the 'issue' is having to weld the pin tower to the frame.

    That and that it isn't a sub mount. Emig Racing makes a bolt on sub mount for the X.

    Yep, but custom machined risers and welded a stem to the frame.

    One thing if you decided raise the bars like I did - if you have ABS, you'll need to raise the "distribution block" they attach to in order to get enough slack in the lines.

    @HowlingMad do you have a photo of the welded part on the frame? As you lowered the position of the stabilised, I assume you have a shorter pin/less leverage- resulting in less (or no) flex?

    Question for the group - it's a long story, but I've inherited a fairing from a fellow xChallenge rider we lost two years ago. I now want to rebuild my XC to look like his so I think I'd like to sell mine. It's the HotRod welding KTM style. I imagine would sell it as a turn key, literally unbolt and put it in a box to make it easier for the new owner. It's seen about 3k miles. If there's an appetite for it, I'll start disassembly, take more pics and do this properly in the flea market.

    I don't have one handy, but I'll try to take a picture later. I think I made the pin and post. Other than having to remove enough stuff to have access, it was pretty drama free. I don't remember even having to weld in gussets. The frame is angled so there was. a lot of area to weld. It's worked without issue for 5-6k miles now.

    I didn't weld my pin on a made up a bracket that used a through hole already in the upper frame tube. It was a simple U bracket that sandwiched around the tube. The bike been through some pretty tough stuff and it's never moved. I can't find the pictures but I'll try to get some if your interested in seeing. I also just faxed a flat plate to mount the stabilizer and drilled two holes in the upper triple tree. The only thing that is important is that the center of the stabilizer shaft is on center of the neck shaft. If not it's not going to work properly

    Here’s a pic of the post and the distribution block I mentioned if you raise things up. 8A96AB9D-4C9C-431A-929C-ADED745FA26F.jpeg FFFF611C-B80D-4063-80A8-43371E64D95A.jpeg

    The subject of replacement throttle cables came up in another thread, EuroMotoElectrics were looking at stocking them but there is still no part listed there

    I only have the basic info in a pdf but dont have details, anyone able to measure the cables ?

    G650X - xChallenge, xMoto 32 73 7 696 788 Accelerator Cable - L=890mm
    G650X xCountry 08-09 46 51 7 708 836 Accelerator Cable - L=850mm

    I only have the cable length on file, I dont know the details as per other 650's eg Length: ????mm with sheath ????mm, nipple size ?

    Looks interesting. Is there any flex in the weld-on pin? With your setup, there's much less leverage.


    If/when do have a photo, would be great. Almost no pics online on that matter.

    No flex that I’m aware of.

    The Husky cables are slightly longer. I don't remember how much but I used them on my Xch and used the Xch cables for my wife's Xco. Husky parts are generally less expensive too.

    I don't think I'll be able to weld another sprocket on because there's not much meat left on the actual spline shaft after removing the first welded on sprocket. So far no leaking of the oil! We made sure to put a wet rag on the engine case and we welded very quickly to avoid excessive heat penetration. 20200922_182853.jpg
