interesting, but i have found the stalling issue to come and go! my bike would stall on start up just like yours, but the last time i rode it it was colder than usual and i completely expected it to stall, but it didnt. weird!

"Sprag clutch"

Hi!
First of all, I salute the advrider community, this is my first post.
Last week I experienced a engine failure that seems like a sprag clutch failure. I opened the generatorr case and see a superfine silver metal powder on the pick up coil, just like the descrition made by Colebatch

The same problem that shagged me for 10 days in Kazakhstan last year, and shagged LucasMT and his BMW dealer for 3 weeks in Poland last year. 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.
I cleaned everyhing, and now the bike always starts.
In yours opinion I must change the sprag clutch as soon as possible? or I can ride a few more Km?

Here goes a video of last saturday track in nothern Portugal ("Aboboreira and Marão hills!?"), have fun!

It will go OK. until it does it again ... then you have to stop and clean it again, change the oil again. Eventually the sprag clutch will be completely fu@ked and you will have to change it.

Changing the sprag clutch is probably the only way to make sure it doesnt happen again any time soon.

But yes, you can run it and clean the pick up coil every time it stops picking up.

No idea who makes them. SO far, I know only of getting them thru BMW and it can be a little expensive ... 300 EUR or so ... because you need to get the metal pieces of the sprag clutch but probably also need to replace the freewheel

The sprag clutch pieces are 12117687777 (about 100 EUR)
The freewheel housing is 12117652871 (about 200 EUR) and the clutch works on the inside surface of the housing. So if the clutch is damaged, then probably the freewheel housing is also damaged.

Cold stalling fixed

they can't be sure it was the battery however bc they also cleaned out the throttle body and idle actuator bc my air filter had been compromised. They installed a K&N.

But either way it doesnt stall anymore on cold starts!
I took my 09 Xcountry to Touring Sport BMW in Greenville, SC and they fixed the cold stalling issue by downloading a new ECU tune as I suggested. Haven't had a problem since. Jeff is the service manager there and he was very helpful.

Misfire

I brought an 07 Xchallenge in late 2009. The bike has now done 74,000 kms and I really enjoy the bike. It has been modified in many area generally to make it a great Adv bike.

Recently it has started to develop a miss fire to the point that it is now in the garage waiting patiently for attention. I am going to clear the throttle body over the week end as I have purchased a new Idle Control Device because it is covered in crap tried an initial basic clean that had some improvement but after reading the treads a thorough job need to done.

The only thing that worries me is the miss fire. The miss fire increases as the bike gets warm which usually indicates coils. They are very expensive in OZ and wondered if anyone else has replaced theirs.

Cheers

Anyone here having the "not starting on a hot engine" problem?

The more I think about it, the more I think it is the autodecompressor failing on a hot engine. Thus leaving a compression ratio the starter can't handle.

Please share your ideas.

I ran out of gas yesterday and the low fuel light never came on. Is there a way to troubleshoot the low fuel indicator?

I have had the "not starting while hot" on several random occasions, usually after very short fueling or throwing-the-water stops. Drained my battery on starting attempts because didn't wait long enough to cool and walked to nearest settlement. Starter turns nice but doesn't even try to fire. When getting more juice with jumper cables and cooled more while pushing, bike will start immediately. Will try Lifepo4 battery for more CCA.

Restarting when warm

Bike intermittently fails to start when warm. Seems to have plenty of cranking amps to turn but won't fire up. Only solution i have thus far discovered is to walk away for 10mins. At least for now that seems to work, But for obvious reasons i am looking to resolve this, would greatly appreciate any input?
