R11 Motronic Tuning for

It’s funny; I remember into the R11 manual that day I brought the bike home and ‘they really don’t us to work on this thing, do For those of you that haven’t one, find one: its a giggle.

As you might imagine, I several of our first months hanging around a lot of BMW dealers, to glean any sort of info I about the new bike. Some were accomodating, some me to quit bugging them, but all seemed to like working on the So I told myself I could do the thing (ignorance is bliss. ).

I am a member of several electronic lists, one of which is dedicated to the and feeding of the R1100. So while we know everything, we had enough living in enough different of the country to help accumulate R11 owners are not unique in this as I’ve never run across any BMW who wasn’t willing to share information.

I put this resource to the ultimate last summer. My R11 required a new position sensor and injector at delivery, as the parts on the bike to be etched with acid by the installing the battery during the The dealer agreed to fix the cosmetic and I returned a few weeks later to the new parts installed.

The injector was no big deal; we just snapped it on. And the position sensor seemed as well, just unplug the connector, swap the parts, and The mechanic (yes, he was probably the one who the battery acid) judged the by ear, pronounced my bike and off I went.

I disliked the new idle right and proceeded to tweak the rotation of the until I got an idle I liked. And I to ride around not thinking I was anything wrong.

We then had a of cold weather in July, and the wanted the fast-idle lever on and longer in the morning, plus it occasionally … when into stoplights, even we had been riding for a long of time. I was convinced it was the fault of the and not tight valve clearances I had just inspected them, so I it by ear and re-synched the throttle bodies at and 2500rpm until I was completely

I continued with the bike this way for most of the summer, but to explain this very tuning method to my Internet with similar difficulties to be hopeless. We needed a way to do it right, a way anyone could duplicate.

And thanks to fellow Oilhead Bob and Gerry at Cal BMW, we can now do it ourselves. just a simple digital any R11 owner can adjust their position sensor like the does, maybe even

Using the DVM, it is easy to the rearmost wire on the four-way used on the sensor. Mine had a rubber donut for moisture blocking my path, and fellow JD Whitaker suggested using a sewing needle to fit thru the gap the donut and the wire. Worked a charm.

I then clipped the positive to the sewing needle, the negative to a handy footpeg bolt, and it was I turned the key on. Starting the bike is not just turning the key on should a voltage reading on the DVM and mine about 350mV. Gerry Cal BMW related that the reading be between 370 and 400mV, so I split the and set it to 385mV.

I’ve received a recommendation from Cal that sea level folks should be at Keep your hand on the while tightening the set screws otherwise the sensor will and mess up your setting.

An note here: if the initial reading is above 400mV, you to first adjust the setting and then after switching the off, remove the fifth from the left in the fuse box to any defaults in the Motronic computer. the computer sees more 400mV from the sensor at it defaults to a preset ‘rich’

Anyway, I rode the bike for a while to get it warm and returned to sync the throttle bodies. I set them at idle (Cal that each air screw sync around 1.0 turns out I think my left is at 0.75 and my at 1.25) and then at 2500rpm. My now sits around 1100rpm and I am to turn the fast-idle lever off blocks of home on cold

Use the procedure published last in OTL to sync the R1100 throttle

So if you know you have a good bike to begin with battery voltage, correct and valve clearances, etc.) and you are having idle problems, may be something worth checking. It takes a few minutes to inspect, and won’t your Airhead be impressed with your skills?

Thanks to the guys at Cal BMW for this
