    I just have to say, how much I am in love with my xchallenge. I recently got it, and had only put about 700 miles on it, all short trips. But I just got back from just about a 275 mile trip today, and besides the stock seat needing to be changed, the bike performed as well if not better than I ever could have imagined! All but maybe five miles were pavement, ranging from 20 mph to almost 80. The thing was so smooth, hit my feet a few times in the corners, I was truly amazed. This bike certainly does seem to be a do it all bike, from fairly technical stuff, to highway riding. I couldn't be happier!

    Hi Guys,

    I developed an issue with my GX650 co but I suspect the issue could happen on any of the three models. After sitting for a while, the two trip odometers and clock reset to 000. Also the cooling fan comes on when the engine isn't very warm.

    Any suggestions what is going on? Thanks.

    Your battery ran down or there's some short that's making it become disconnected.

    My fan comes on pretty regularly after idling for a few minutes. I assume it's just set to trigger early. How warm do you mean when you say isn't very warm? Are you moving?

    As long as the fan comes on but the temperature warning light stays out you'll be fine. (Do check the coolant level every now and then)

    I had the odo and clock issues as well. Fitted a new battery and all is good.

    My first thought was battery. I hooked it to a trickle charger and the charger says it's OK. This bike is an 07. I'm very familiar with it. The engine is just up to temp when the fan comes on - this is new.

    Added data point I should have included earlier. I had the bike in for a service with an indie who doesn't usually work on BMW's. I did check the coolant level and it's fine.

    Back to the battery. It's old. Is is possible that the battery is not up to snuff but the charger says it's ok? The bike starts easily and the starter sounds as if it's running a full speed.

    Whenever you disconnect the battery it will reset your trip ODO. So you're saying you took it in and then it was 0? If yes, that's an easy, easy answer.

    edit: fan is new like new it's just so happening to be the case now that it's 20 degrees warmer outside that it comes on 20 degrees sooner or new like overnight? either way I would worry a lot more about it if it were the other way. Not like having the fan on is going to do anything. If the new shop changed your coolant then I'd just check to make sure the system has been burped. Rock it from side to side while squeezing the coolant hoses and you can get a lot of air out if you/they haven't alreayd.

    The battery is well connected now. There is no indication that it isn't. I set the clock and accrue a few miles on the trip odo. I ride some. Park for two hours. When I start up again, the odo and clock are zero's out. The shop did renew the coolant.

    How can I rock the bike AND squeeze the coolant hose? Wouldn't riding a the 20 miles I have since getting the bike from the shop burp it?

    There is air in the cooling system. I'm pretty sure of that by the story of a coolant change.
    There's a small bolt on the head just in front of where the plugs are above the thermostat housing. Undo the filler cap, take the bolt out and start squeezing the hoses. Put the bolt in when coolant comes out of the hole. Fill coolant tank to level and you're good.

    Do that with a cold engine !

    OK. got it. I may have two problems. The battery may be unable to hold a charge and the coolant needs burping. Is the head screw accessible without taking the pod off?

    Is it possible, do any of you guys think, that the battery could be so low as to reset the odo / clock to zero but still be able to start the bike? Seems unlikely to me.

    I sit on a little stool sort of in front of the bike and have my left hand on the left coolant hose and my right arm rocks the bike back and forth. Then vice versa. And no, apparently not. :)

    Shot in the dark: another diagnosis might be that you have a short in the harness that has created gremlins. The first gremlin is resetting the display unit when you are shut off. The second gremlin is making the temp sensor read erroneously high, and kicking on the fan. Maybe set the display to read volts, and monitor that on a test ride? Should be pretty solid on 13.2 to 13.4V in my experience with no extra lights or heaters on.

    But bleeding air from the cooling circuit is straightforward and worthwhile doing after any coolant work.

    Thanks. I'll first try a test riding monitoring the volts and if it's steady, then figure I got a burp and a new battery needed. I do keep it on a tender when not in regular use (dead of winter) but the battery is 6 years old so if it fails now I can't complain.

    CAn anybody tell me exactly where the bleed screw is in the head? I'm not good with this stuff and am leery of making the mistake of wrong screw removal.

    And yeah, I think I can rock and squeeze.

    I had the trip ODO's reset when my battery was low but the bike would turn over and start fine.

    On the fan issue I would burp the bike. BTW: The bolt is just above the radiator hose on the right hand side of the bike and you should be able to get to it without having to pull anything off the bike if I recall correctly. (Not looking at the bike right now so hopefully someone will correct me if I am remembering wrong)

    Let us know how it turns out.

    Has anyone purchased a centerstand lately? Looking for one that fits. Any suggestions?

    Look what followed me home today. Well that was the most straightforward decision ever!
    07 8k
    de-decaled X
    bark busters (OEMs)
    fairing blacked out along with the seat
    ALU skid plate.
    Probably original Scorpion tires.

    I handed over the proverbial envelope of cash then went for a spin and never once asked to see my cash again. BOOM!

    Here's a few more cellphone pics.

    Gearshift mod and oil change next. Tires were actually Sahara Enduro 3s which are ok but not great.

    What's the verdict on side crash bars like Motech or TT for the radiator and reservoir?
