    Wow.... that is a pretty strange procedure, and I am really puzzled why this info doesn't seem to be anywhere, including the BMW maintenance manual.

    Why doesn't it just drain down into the case when you open those screws?

    I did leave the dipstick open a bit to neutralize the pressure. What I ended up doing, and I won't do it again now that I hear what you have to say, is ran the bike in very short spurts (3-5 secs), which brought most of it down to the case where it drained. I did this over the course of several hours, letting it drain between spurts. What an ordeal, I must say! But, looks like it's finally ready to receive new oil.

    As far as the tube you mentioned.. is this a plastic tube I need to acquire that slides over or would I need something threaded? Also, is there a specific diameter of tube you recommend?

    Once you pull that rubber cap, does it just start pouring out behind the oil reservoir or does it only begin to flow once you have a tube on/inserted ?

    Thanks very much for the info. Wouldn't have guessed this was the answer to save my life.

    Paul

    Dry sump engines like the G use positive pressure feed for oil delivery from and to that tank. It's not gravity feed. If it were, the sump would fill up with oil making the engine impossible to run.

    That information is in numerous places, including other Gx threads and f650.com. Please search. And if that doesn't work for you, post in an appropriate thread -- this is a log of issues/problems with the bikes.

    to onemoreokie and any others with the intermittent stalling that they attempted a Voltage Regulator replacement to fix - feedback? Did it work? Did you give up?

    I'm still going strong here.

    I've also got a starting problem, and was wondering if this sounds like what others have experienced, if it sounds like the battery. Several times recently I've taken the bike off the tender and gone for a ride. If I stop after 1/2 hr to hour and attempt to start it back up within minutes of stopping, it has a difficult time -- as if the starter is not being cranked with enough ooomph. Even more puzzling is what happend to me today, as after a few failed attempts and letting the bike sit for 5 minutes, it fired right up. I actually had the original battery replaced under warranty about a year ago, before BMW began somewhat admitting there was a problem with the battery. But of course it's possible I got a second bum battery. Eh?

    I DID get a second battery which failed as well. Both failed after regular riding. The second in the middle of a long trip too. In my cases, the failure was instant and complete. There was no 'weak battery' sense. Just good cranking one start and dead dead dead the next.

    Son of a bitch! I just went down to the garage to experiment, and I got it to exhibit the no-start behavior -- in neutral, clutch engaged (lever out), sidestand down -- crank, crank, crank but no start. Tried a few configurations, with sidestand up, in gear and clutch disengaged, etc ... got it to fire right up. I'll have to play around some more to determine a correlation; I couldn't immediately say whether it was sidestand or neutral sensor related, as I got it to start in the first configuration that failed, but that was after I put it in and out of gear and dropped/lifted the sidestand a few times. Now if some sensor was preventing it from starting, why would the system allow it to crank at all!?

    Thanks satur9!

    Don't have an answer, but want to ask clarification about cycling the key all the way to "off" before trying the restart. I've heard (maybe just bull-- guys talking around the campfire type thing) that cycling the key forces the ECM to re-evaluate running conditions (fuel, voltage, air temp etc.) so it can adjust mix and spark for optimal starting. Don't know if that's true, but do you remember if you cycled the key between the unsuccessful trys and the successful trys?

    FWIW, I have the same problem. '07 xCountry. Stop, fill up, bike barely turns over and won't start. Let it sit 5 minutes and it fires right up. I've tried all combinations of kickstand up, down, neutral, in gear, clutch, etc. Nothing seems to work but letting it sit. Must be heat related, but what?

    Yeah, I fully cycle off the key for a few seconds between tries. And let the system fully come up before pushing start.

    I have just got my bike; Xchallenge; on the road after buying it with some cosmetic damage and repairing it myself , I believe that the battery has already been replaced. The bike demonstrated an intermittent startingproblem when warm .
    Sometimes, when I hit the starter button, the starter pinion does not engage; so I hear the startermotor go whizzz, but no cranking sound. I was lucky to be able to bump start it but as I was in the bush on two occasions, the anxiety levels rose a bit. Whizz, whizz, whiiiiizzz

    I checked the side stand was up and made sure the bike was in neutral
    I also tried puting the bike into gear and rocking it back and forth to change the crankshaft position, but no joy.
    After bump starting, I can turn it off and it will start normally

    sounds like a starter sparg clutch issue (the starter pinion does not move in & out).

    OK , yes of course, I was not thinking properly (working on older cars a bit lately)

    The starting problems you guys are experiencing are coming from the solenoid...remove the right rad shroud, there's a couple tiny nuts on the solenoid that vibrate loose and build up resistance..take them apart and put dielectric grease and lock tite the nut after you replace...

    The motion of getting on off the bike is enough to get the dirty contacts to work, thsn not work....

    I also had this problem, but found the culprit on the trail one day...

    The other big problem is the kickstand switch. ..disable it or bang it next time she gives you a hard time starting. .

    if the solenoid or the kickstand switch were not working, the starter would not spin at all. as i understand, the symptoms were the starter spinning but not turning the engine over.

    Modifications (if any): NIL
    Description of Failure(s): Engine cut out during a power-slide. There was no lights or anything coming on the dash.
    Resolution (if any): Pulled the front end apart looking for loose wires. A wire must be loose in the ignition pod since I can bypass the ignition and start the bike. I cant seem to get the ignition pod apart to check the wiring. Has anyone else had any luck doing this?

    Stopped by the dealer to have them take a look at my weeping master brake cylinder cap. Replacement of cap and diaphram will be done under warranty. They said they will also replace my battery when I come back, as part of the recall campaign.

    Let us know what type of battery they will fit instead.

    Had the no-start problem again this morning as I stopped for gas. I hadn't noticed this post of yours, toofast4uu. I'll have to check into this ... as this issue is sufficiently pissing me off. Can you confirm that the symptoms caused by these loose contacts are crank, crank, crank but no start/catch?

    I've got a new battery coming from BMW, but I don't think this starting issue is the battery because when the stars are aligned, it fires right up. Or could, as some have said, that some internal defect in the battery prevents if from putting out quite enough juice?

    This is not true, at least as far as the sidestand switch. Try starting your bike with the sidestand down and in gear. It will turn over but won't catch. Brilliant, right there.

    Anyway, again, after bitching for a few minutes and declining the gas station attendant's offer for a jump, and listening to his "should have bought a Harley" wisdom, it finally fires up.
