Even a dealer can spend ages trying to find this one, The diagnostics for the X-Challenge are pretty basic to say the least and they wont give any clues as to what this problem is.

Lay the bike onto its left side, open the generator cover, swipe your finger over the pick up coil and its terminals .... if you have superfine silver metal powder on your oily finger, then there is your problem.

If thats the problem, you probably should replace the sprag clutch, your oil and filter. And get the pick up coil super clean.

If its not your problem, it will have cost you 20 minutes and probably a $4 generator cover gasket.

Thank you so much for this Cole. I will give it a go tonight

Thanks also tmotten for this resource

I am feeling more energized now

[Colebatch]

as a quick fix, you can just clean the pick up coil, change the oil and filter, but it will be only a matter of time before it happens again.

There are two bits to change on the sprag clutch ...

12117652871 FREE WHEEL HOUSING
12117687777 FREE WHEEL

And they aint particulalrly cheap

Why this happens on X-challenges but not on the F650 GSs I dont know

My worry was a failure on a trip that would render the rear suspension useless. At least with a standard shock/spring configuration a shock failure does not render the bike not ridable.

I did like the feel of the air shock when I had it on the bike, but the ohlins is better. There are a few other options, I just went with ohlins.

I did have to modify the reservoir bracket as I have the H&B bag mounts but that was relatively easy if you have drilling, cutting, and grinding equipment. If you don't have the H&B bag mounts there is no issue.

I would prefer the ohlins too. Meanwhile, I have had to deal with the airbag. I noticed the rubbing had got worse on a recent trip (a long way from home...). I wrapped the airbag with a few rounds of duct tape. This doesnt interfere with its action, and provides a good sacrificial layer. After another 3K kms, I notice the tape is showing no wear. Quick and easy peace of mind.

has anyone got the KTM part number which is molded onto the plastic part of the TT rear chain guide? I ordered one off the 640A thinking it was a guide; I got only a half guide so its only offering protection against a foot getting caught in the sprocket.

I need a full guide.

thanks

Walter, Lucas,
Were you guys using the standard drain plug or the Touratech one? I was using the Touratech one because the stock one stood proud of the bashplate, but have swapped back now that I have Stephan's bash plate. I wonder if your problem was due to the lack of magnet in the touratech plug?

Fortunately I have had no problems with swarf fouling the pickup yet (21k miles).

I'm using standard - as Touratech one has no magnet on it. So I would not suspect that as a cause.

My drain plug normally looks like one shown above.

My BMW F....ing dealer was repairing that issue for 6 weeks ! they even replaced a BMS-C in meantime (no comments).

I think that real time sensor values should be displayed on diagnostic computer so for dealer finding that problem should take 30 minutes.

Rob,

don't forget to get your rear splashguard replaced - it's a recall item.

I think my dealer has tried to "pull a swifty" the "new" guard looks suspiciously like the original one.

Does anyone know where the photo of the original and the replacement splashguard is?

[Matt]

I hang my head in shame........I snapped an axle pinch bolt.

Now that I will be using a torque wrench for my nuts....... .......is there any reason why I can't use stainless from my fastener supplier??

I hope that the pick up coil that you refer to is this thing



I have used a toothpick to indicate a deposit of fine metal fragments. I am hoping that there was enough there to be the cause of my problem. I unfastened it from its housing and washed it. I will try and get a gasket and oil filter tomorrow - reassemble and test

Yeap thats the sensor that Cole was talking about

[Colebatch]

thats the one ... and for the earlier question, I also only use the original sump plug. It collects the big chunky flakes of metal fine, but some of the finer stuff shorts out the pick up coil once the sprag clutch starts to go.

Not sure, but SS bolts are generally more brittle. I think I would probably avoid SS in a high stress location.
