rpm's, as this can potentially suck mercury into the motor. If you need to make an

adjustment loosen, or slacken in BMWese, the 10mm lock nut on the cable nipple. Turn

the cable nipple in or out being careful not to turn the cable housing at the same time.

Keep checking to make sure the cable turns freely in the nipple. Make small

adjustments, 1/2 half turn in or out can make a difference. Once you get the mercury

columns to rise together and settle fairly closely at various rpms you are done. Secure

the lock nut and check one more time.

If you still feel you just don't have it right you can always have you dealer use the

BMW Synchro on it.

Throttle Body Sync - Jon Diaz

How To Synch Those R1100 Throttle Bodies!

As an R1100 pilot, you've likely felt it: that little hum in the turn signal switch or the

vibrating mirror you can't see out of or worst case, a bike that surges so badly at part

throttle you can't ride smoothly. It's all part of those first days of R1100 ownership, and

very easy to deal with.

When you twist the R1100 throttle, the cable actuates a cam on the left throttle body,

which in turn actuates a cable that crosses over to the right throttle body. The cross-

over cable tends to stretch during those first few months of use, and this is why the

cylinders fall 'out of sync' with one another at part-throttle settings and give you fuzzy

mirrors.

I purchased a mercury manometer (Carb Stix) from my local dealer to use for this

procedure. It consists of rigid plastic tubes sitting in a reservoir of mercury at one end,

with flexible hosing attached to the other end to plug onto the taps at the throttle

bodies. You will also need a 10mm box-end wrench, a flat-blade screwdriver, and

needlenose pliers.

Temperature of the motorcycle engine is critical to the success of this operation. I like

to run my bike for at least 15 minutes before returning to the garage to perform the

operation. Too hot an engine is bad as well, so avoid excessive idling or traffic during

your warm-up period. If it is really hot outside, use a room fan in front of each cylinder
