wolcott Posted May 4, 2006 Share Posted May 4, 2006 I have a '98 R1100RT that I bought last summer with about 17k on it. Shortly after I bought it, I noticed when I activated the fast idle lever it would not return. I had a couple of inches of slack hanging out. I tried blipping the throttle and adjusting it up top to no avail. I looked in the Haynes manual and it said an 18k service would be coming up and that the throttle cables needed to be replaced anyhow along with a TB sync. As I was new to wrenching on BMW's, I just changed the plugs and did the valve adjustment. I started reading this web site soon after I got bike. Anyhow, last summer, (a BMW shop that was recommended by one of the guys here, as one of the best) replaced the fast idle cable, and the various throttle cables and did the TB sync. This winter I noticed that the fast idle lever wasn't working as well as it should. It seemed to have to much adjustment and would not raise rpms too much. Because I've been going through radiation therapy, chemo, and all sorts of other stuff for my cancer treatment, I finally drive the 160 round mile trip up to this BMW dealer. I go up there the other day, and the service writer or manager (really not sure which) took a quick look at it and said he could fix it. He adjusted it, turning the long silver, knurled adjuster this way and that- he told me he liked about a 1/16" of play and then tightened down the locknut and slid the rubber boot over it. When I got home, I thought he might have put the locknut in the wrong position. In the Haynes manual, on page 1.13, in the upper left hand corner, picture 8.10a, there is a pic that shows the locknut locked up against the black swithgear side. This guy has got the locknut up against the long, silver, knurled adjuster. Would someone be kind enough to tell me how to adjust the fast idle, what sort of clearance i am looking for, etc. I do know that I will put the locknut back in it's proper place against the black switchgear. Book says "on 1996-on models cable (choke) freeplay should be zero. I saw one post when i searched that said 1/8" to 1/4". I assume freeplay is measured up top, but am not sure. Thanks.
