    Scofflaw! You should have stopped and told those nice elderly rangers that you had broken the law and deserved a citation. :lol3

    But back to the topic at hand, I think your battery was not dead--it was just dead enough to not have enough juice to turn the starter. But it DID have enough juice to run the ECM and fuel pump and fuel injectors (which need way less amperage than the starter) so that when you bumped it the plugs fired and you got ignition.

    Nice going by the way.

    I would check the bolts from time to time. I have had some try to back out on me. I have a steel subframe and have carried a pillion and 2 mountain bikes on the back along with my regular luggage and have had no troubles. I have been thinking about bobbing my X and trying to maybe score an aluminum subframe without pass pegs. Anyone know if the weight saved will be worth the hassle?

    Best wishes on your journey!

    Indeed, the battery was not fully dead. It just wouldnt spin. Had I left it sitting for an hour or so, perhaps it would have regained enough surface charge to spin. I have experienced that as well.

    Just picked up my first BMW a couple of weeks ago, love the bike, but it's starting to get on my nerves with starting/stalling issues. I've read a lot on the subject and hate to bring it up again but haven't found much on why my bike, 07 xmoto with 5.5k miles, stalls for the first minute or so even when it's warmed up. It'll fire, idle for about 15 second then die. The bike had just been serviced at Max BMW in NH before i bought it. Had 3 recalls done, the battery because it wouldn't start, the chain roller, and something else.
    When the bike warms up, it runs awesome, no stalling, hardly any surging. If i park it for more then 5 minutes, it'll start right up, but die right off. Voltage during that time is around 12.5. Once it hits 13.8-14 it'll idle fine. I've cleaned the idle actuator valve, pretty dirty, but it didn't help. Also re did the vacuum lines where the previous owner had removed the EVAP canister and didn't hook the lines up correctly.
    One more question, i noticed that the voltage when riding the bike stays around 13.6-8. sometimes, i'll look down and i'll see 11.5-6 then it'll pop back up again. Normal? Should mention that the air temps are around 50F right now during the day. Starting when it's 30F does the same thing.

    I wrestled with this for five months and solved mine just yesterday (kinked fuel line between xtank and main.)
    There are at least a few different root causes, so last fall Xfrog wrote up this great list of remedies to try.
    Good luck! You will naill it.

    I have had my voltmeter fluctuate between the 10.9-15.2 range depending on useage, but seems to run 14.2-14.3 regular with no heated gear or aux lighting.

    I read the link to Xfrog's post and would have to agree that the problems are likely from several areas making proper diagnosis difficult. I think at this point it is still a "throw a few different parts at the problem and see" type of deal. Mine will stall when cold(under 45F)....sometimes....once only.I don't let it warm up. I just jump on and ride. I have removed my sidestand switch and feel that it creates intermittent problems causing the root problem to be difficult to catch(in much the same way that the faulty solder in the ignition switch can cause diagnostic nightmares-on my list of things to remove from my bike). I have removed my Canister and rerouted the vent hose as it can get pinched by the seat. I have a heavily oiled UNI filter and have not cleaned any sensors-nor have I had any problems caused by excessive stalling. I did have poor performance issues when my stock exhaust plugged up with it's own vomit. A non BMW exhaust cured that.

    My advice would be to perform one task at a time rather than try all of these things at once, if you actually want to know what was wrong. Hopefully I can be of more help when/if my bike has these problems, but I may have already removed it. Please keep us posted, as I'm sure many would like to know what is really going on. I really love my little bike, so I will plan on working thru these problems if they arise(swap in some funduro carbs:rofl:huh:dunnomaybe) 13K no probs so far*fingers crossed*

    It would be nice to hook up a computer to the ecm to do a little data logging to see what's going on when the stalling is occuring. This problem dosen't seem bad enough to throw a fault code to be able to catch it in the act.

    Have tried that a couple of times thinking that it might not have worked right, still didn't help.

    Here is a list of things i've done:
    Reset ECU
    cleaned idle actuator (pretty gummy, but not as bad as some of the pictures i've seen)
    reset idle actuator
    reset throttle position
    run fuel injector cleaner (lucas)
    fixed vacuum line routing from the canisterectomy
    tired gas from 3 different stations so far
    new battery from BMW about 2 weeks ago

    Pretty sure thats everything so far. The throttle body wasn't that bad so i didn't touch it, yet... Bike starts then stalls the same way, whether it's a cold start, or a warm start after sitting for more than a few minutes. What i have noticed is if I keep it alive with throttle, after a couple of seconds, i can get the RPM to steady out, somewhere around 2500 RPM if i had to guess, without stalling, then about 20 seconds later, the RPM with climb up a bit without any more throttle. After that, it'll idle perfectly.

    I rode the bike for about 60 miles today, only stalled once at a light. But every time i stopped and let it sit, it was a fight to get it going again. It'll fire up super quick, rev high, then drop down to idle speed, then start to get a little loopy, then die.

    Here's one not on the big list of stuff to consider/try -- engine coolant temp sensor, solved it for one inmate:

    Have considered that too.

    Have a question on resetting the idle actuator. When i do the reset, i don't hear it do anything at first, but when i turn the key off, i hear it make sorta like a clicking sound. Almost sounds like it's sticky. Is it suppose to sound smooth? Sounded like this before and after the cleaning. Would it be harmful to run it through the reset while it's out of the throttle body to see if it's moving correctly?

    Took a ride to Philly last night. Great route down from nyc with lots of twisties, then cheesesteaks and some nice urban riding around town.

    Yesterday. No cheesesteak. No flowers. No humans. Was planning to spend the night, but returned home. 412 miles.

    That's why I like to ride at night.

    I'd rather ride where you were.

    Quick clip of the starting/stalling issue. Does this every time the bike has been sitting for more than 5 minutes.

    Bonjour,
    Xch end '07(first owner-15000km),still troubles with idling until warm.
    Followed all the tips(also cleaning actuator-which wasn't dirty) was worst thereafter (15' fidling with acc until warm enough)
    Then saw somewhere to place a resistance of 10Kohm beween air temp.sensor and the "controller".bought the resistance(15 cts) put it in the wire and have since no troubles with idling!
