    K13GT - 2009. Won't start when hot.

    New to me bike and I notice its not starting up as smooth when it's warmed up. Today after a short ride I stopped for lunch and got a quick carry out. Nothing... when trying to thumb the start button. Gonna let it cool down while I eat my lunch. Anyone have an idea what the issue is? It's close enough I can walk it back home... but I'm thinking maybe battery issue? Thanx for any thoughts.

    Update... found thid on another post... "Second issue is the starter sometimes will not turn the motor when it is hot. This is due to undersized wire from the battery to the starter. This is corrected by running another wire parallel to the existing wire or replacing it with a larger wire. I replaced mine with a six guage wire." Maybe this is the prob??

    That's correct, there is a service bulletin for the repair.
    There was also a recall for the switches, you may want to ask if the recall was done.

    Lee is correct, and there is an SI bulletin for the issue. Iíve tried to find a copy and havenít been able to, but I seem to recall a kit that had the heavier wire and a couple of other bits as well, including a relay. Lee, do you recall that? Too bad I-BMW was pulled out from underneath usóthe SI was well-detailed there.

    The part number for the starter wiring upgrade kit is 12418532735
    which includes heavier gauge hot wire, heavier gauge starter relay
    wiring, and a heavier duty starter relay.

    I had posted a related question about battery sizing for my K1300 S hoping for a work-around to the hot-start issue. To help others benefit from my research, the BMW Service Bulletin number for the hot start issue is 61 002 11, which you can find via this link: https://static.nhtsa.gov/odi/tsbs/20...47121-9999.pdf

    Not sure why itís so well hidden.

    Any BMW dealer can do a search on service bulletins for any BMW motorcycle. You should ask your dealer if all have been completed on your bike.

    Bosch relay number?

    The closing date for the campaign was December 31, 2015 and that part number can’t be found at Bobsbmw.com, maxbmw.com, or RealOEM.com. I haven’t queried my local dealer yet, but if he reports NLA then does anyone have the Bosch number for the heavy-duty starter relay? The cables could be made up using the originals as templates but the OP would need a Bosch number for the relay.

    Here’s a photo from MaxBMW website, but no start/end date is given and no indication of whether it is the stock or HD version:

    UPDATE: sierrabmw.com still lists that part#, at $160, so possibly it is still available...

    Tyco Electronics is now TE Connectivity - https://www.te.com/usa-en/home.html
    I didn't see that specific p/n when I used their search box, but the base number is there, so maybe they have a substitute.

    I think your photo shows the later style relay BMW part# 7 704 174/02
    the original relay shows part# 7 704 174/01
    all the other numbers were the same between the two relays
    real oem shows the relay to be about $14.00
