    R1100R balking is Back!

    I thought my new-to-me '98 R1100R was cured of its running problems. Now it starts up and runs like crud for about 5 minutes and then runs great. Once it has run for about 3 miles it has good power, it's smooth, has nice throttle response, and drops back to idle well at stops.
    When first started cold it lurches, balks, won't idle well, and has poor throttle response etc.
    It has just had the valves adjusted etc. at a dealer (6000 mile adjustment, new plugs) It has been run little in the past year+ and only 47 miles this summer until I bought it. I have put on 200 miles with gas treatment three times (injector cleaner, seafoam, techron) in proper proportion and gas added three times (High Test) with the tank full now. Bike has 6,475 mi.
    Help. What should I do next? Winter is getting close here.

    My hunch is the engine temperature sensor is telling it the engine is hot, when it isn't.

    Thanks Paul,
    Would that be: (12 61 1 341 602 TEMPERATURE SENSOR 0.13 1 $89.64) from the MAXBMW site?
    Or (12 60 1 341 387 OIL TEMPERATURE SWITCH 0.07 1 $55.36)?
    Or (13 62 1 465 108 TEMPERATURE SENSOR AIR (from 01/97) 0.06 1 $39.60)?
    I bet you didn't think I could be this ignorant! BTW I found the air temp sensor in the airbox but have not found either of the other two sensor's locations. My Haynes manual is on its way. I'll check the BMW repair manual I downloaded from the police site.

    12 60 1 341 387 OIL TEMPERATURE SWITCH shouldn't be in your bike - discontinuted in production after 8/93


    12 61 1 341 602 TEMPERATURE SENSOR is what replaced it in 9/93. This should be the item in question. If I remember correctly, I think it is on top of the block, behind the alternator, on the right. I can't promise you will find it there, but I think so.

    EDIT: I'll put money that this is it, circled in red; might be a bit more under / next to the alternator than behind it, but on the right. You can also see part of why my '96 became a parts bike.




    13 62 1 465 108 TEMPERATURE SENSOR AIR is measuring intake air temp, not engine temp and probably isn't the culprit.

    I should have spares of 12 61 1 341 602 and 13 62 1 465 108 with about 20k miles on them from my '96 parts bike if you want to try them out.

    You may want to start by cleaning the contacts and plugging the switch back in to see if you can get lucky.

    Paul, Would this show up on the RID? Does a R1100R even have a RID or temp gauge?

    The previous owner had an unfortunate encounter with a coyote, followed closely by a telephone pole.
