    I somehow managed to break my side stand switch, which at $126 a pop, is a bit annoying. The little locknut was spinning 'round on the threads of the bolt, but that was nothing new, so I didn't think I'd broken the switch. But when the bike ran poorly (intermittent connection), it turned out that I did.

    Anyone else break it by over tightening?

    Similar issue.

    When I lengthened my side stand and refitted it, the nut just kept spinning. I stopped as soon as I realised it wasn't tightening.

    So far it works.

    When it stops I'll have to figure out how to remove it and rewire the sensor to run without.



    Anyone know how to bypass it? Obviously any advices comes with a disclaimer.

    Just connect red and white. Brown can be left alone, no need to do anything on that. It worked fine for me for few months and then I desided that enough scary moments and installed new one. It really is a safety device. Though the original lenght side stand is not the worst one to throw you and the bike to the orbit.

    When you installed the new one did you have any issues with the canbus throwing any codes? I'm about to replace mine

    No, nothing. The only pain in the ass was to play with the cable ties (at least the one behind the connector).

    As far as I know this device is just a stupid potentiometer with no brains what so ever.

    It figures! The torque spec for that little nut is only 5nm!

    Mine went bad so I just tied the red/white and left the brown to float. I don't think I will ever replace it, although maybe I will have a scary kick stand down moment and recant that opinion.

    D'OH!

    That figures then.

    I had to lengthen my sidestand, after all the suspension upgrades, by about 50mm. Stands nice now, and I put a bigger foot on the bottom.

    I was at a service station and a guy with a truck was waiting to fuel up when I finished, so I pushed the bike forward to allow him space to move to the pump. They build like a speed hump all the way around the pumps at some servos here to contain spills and run off....so side stand hits the hump and levers the bike away from me unexpectedly...I try to hang on and go down with it.

    While I'm standing there about to explode with rage a passing local bogan scrag (female redneck) says "Havin a shit run o' luck today...aint ya".....oh...no...you...didn't...

    What I said next was not worthy of print here...suffice to say that 5 years in a Dockyard, 8 years in an infantry rifle section, 18 years in construction, countless years in seedy bars and a lot of years growing up in some very bad areas (referred to locally as "the Hood") contributed to the language, rants, threats and tirade that ensued. If I'd been armed I'd be doing 15 to life about now. (I may have some minor anger issues)

    The scrag made a beeline for her car, the truck driver got back in his truck and I left the BumW laying on it's side blocking the truck in, and went and paid for my petrol, eventually leaving the driveway on the back wheel.


    It's not the switch that's the issue. It's the angle the stand locks at. I've learned the hard way to walk the bike while on the opposite side to the stand when moving it manually.

    BumW take something as simple as a sidestand and turn it into a device that over complicates things and attempts to kill you for no good reason....so then it needs a safety switch.


    But in hindsight it's piss funny....

    Stands at the same angle as standard, due to the increase in height. Increase. To make larger or longer.

    Or did they stop teaching comprehension over there?

    It sounded like you changed something to make the stand act differently.

    I always thought the switch was required by the Goverment safety people that try to make everything harmless.

    there is a sidestand switch on most?? new bikes. and it's very common for people to disable it. It's one of the many "no cost improvements" done to KLR's when ridden off road.

    I don't get blameing BMW for putting a devise to kill the motor with the side stand down IF ITS IN GEAR, You disabling it,and then forgetting to put your bike in Neutral and having an OH SHIT moment.

    Yes, but the design of the stand, locking so far forward, means that if it does dig in, it throws the bike to the right past centre.

    Over the years with the bikes I've had, some could be ridden away from a standing start with the side stand down, and the first left turn would flick the stand up and you'd barely know it. They used to have that little rubber do-hickey on them for just that.

    On the BMW, if the switch were disabled and that happened, it'd throw you far enough to put you under another vehicle.

    Which makes the side stand switch almost a life and death necessity. When it doesn't need to be.

    Over designed. Over complex. You couldn't deliberately design something to fail and make it work as poorly as BMW do.

    They have a knack for it.

    My bike recently developed an odd problem - it occasionally fails to start when I press the button. Lights are on and bright, cockpit displays all on, sidestand up, in neutral, clutch in. Press the starter and nada. Zippo. Wait a sec press again and it starts. A few times it took a couple of minutes before it would respond to the button and fire up.

    Could this be related to the sidestand switch? Any other ideas before I pull the switch housing apart?

    My experience with BMWs began back in the 70s when I used to service them and ended in the early 80s They were off my radar until I bought a new 2010 f800gs.
    Their side stands on the air-heads back then were spring loaded so if you took the weight off it would immediately retract.
    I guess it was their idea of a safety feature. However, they were very easy to push off the side stand whereupon the bike would fall over. So nobody used to use the side-stands, ever. The default, even for brief stops, was the centre stand. Which was nicely balanced and easy to use.

    So 30 years later I finally buy myself a BMW and find it's all changed! The side stand is much improved, but still doesn't lock down under pressure like the HDs and the centre stand is so forward biased that it's relatively easy to push the bike off it if you're not careful. Good idea to use a tie-down to keep it from folding back if you're working on the bike on the center stand.

    Clearly they went from one extreme to the other then.

    As for not starting and then coming good, the unfortunate thing with the CANBUS system is that it is hard to diagnose without having a code reader. The nature of the system is that an intermittent fault may not present with directly attributable symptoms.

    You would have to bypass the sidestand switch altogether and have a number of fault free starts before you could "assume" you'd identified the issue.

    Refusing to start like you described is similar to what mine does when the gear position indicator switch gets wet.

    So far it's only happened when I've been running late for appointments or for work.

    The easiest way to solve the starting issue is to take it to the dealers and hope it plays up while you're there. I have had some experience with vehicles at dealers with intermittent faults. It's frustrating beyond description. When you hand over a couple of hundred dollars and hear "if it doesn't do it while we have the code reader on it there's nothing we can do".

    It depends on the level of fault logging in the CPU.

    I object to your use of foul language. To wit:

    "Take it to the dealer".

    Shoot me now. Of course my warranty & roadside assistance just ran out. I'm planning a three week trip for September, part of the GDR and then Forever West route, so it would be nice not to feel like I'm rolling the dice every time I press the starter. Worth talking to them about it I guess.

    I had the sidestand off again today and discovered that the issue is that the section of the bolt that passes through the switch doesn't have a long enough thread. The nut has been screwed on until it ran out of thread. This chewed the thread out of the nut.

    So I have a temporary fix in place with substitute nut and locktite and a couple of washers.

    I seems strange. The switch mechanism is narrower than the plain section of shaft it mounts on. So it is quite loose when mounted properly.

    Just the nut? Lucky you. I stripped the thread off the pricier bolt.
