My throttle does close on it's own :(
This has happened gradually over the past week or 2 (200+ Miles)
It seems to have gotten even stiffer as well, or my wrist is getting weaker :rolleyes:
Cables are the original '02 junk cables so, I thought they might be hanging up in the housings. That does not seem to be the case as I have pulled the cables off at the grip end and they seem to move freely in the housings. Tried to work the throttle by pulling on the cable, no joy it is just too stiff. Handgrip moves freely on the bar.
Cruise still works. However when I disengage the cruise I have to push the throttle closed.
I really don't want to pull everything involved with removing the throttle bodies. But will do so if that where the problem lies.
I have threatened to get out the WD40 :rolleyes:

Every once in a while I find that I need to slow down or even stop :rolleyes:

Just curious, but have you ever lubed your throttle cables? I do this on an annual basis for my motorcycles. The lube cleans it as well and does make a difference. If it is not the cables, check the pulleys it connects to and make sure they turn freely. And don't forget to check and see if your throttle grip mechanism itself needs to be cleaned and lubed.

What is the correct procedure to lube cables? The BMW manual does not seem to cover this procedure.

While it is a PITA, the cables can be replaced w/o removing the fuel rail or throttle bodies or anything like that. You do have to get the kit that goes at the grip, the cables. John Bowles, Wcarter, and myself (mostly John and Waymon) were able to do that in a couple hours at a tech session with basic hand tools and a long hemostat. May want to search it out here. Made a dramatic difference in the feel of the cables.

Mine idels far too fast, unless I force the throttle back to the stop.
At the moment it just seems to want to stop high.
I bet they are both down to adjustment

I would suggest you install the new style throttle cables. Cost about $160.00 for the part - you'll notice a huge difference, even if you had no problems before.

If you don't want to do it yourself, probably a couple hours labor for the dealer.

When I Had my bike apart this winter, I had some similar problems but my bike was already disassembled. However mine was a tight throttle tube. I also had the throttle catching at almost full throttle, (engine off, not running). I had put the airbox clamps that connect to the throttle bodies a little too close to the pulleys causing them to catch and stay open. Just a something to keep in mind if you do have to remove all the junk to replace your cables.

Absolutely - you have to be very careful putting it back together.

FWIW, Clymer manual says that you have to remove air box, and fuel rail to get to cable on the engine-side of things. I did remove air box - but was able to get cables into place by using an extra-long pair of hemostats to snake it into place. It pays to have a father in law who is a surgeon to get some "specialty" tools!

The LT cables DO NOT get lubed. They are teflon coated on the inside and lubing just causes them to collect junk and stick.

You're bike is not returning to idle because the cable has frayed somewhere. If you don't fix it soon, you'll be stuck with a broken cable somewheres.
I used silicone spray to lube my stiff throttle cables in 2005. Two and a half years and about 35K miles later they are still doing fine. The silicone spray was about $8. I think that BMW has about as much expertise in throttle cable maintainance as the do in final drive design!:eek:
