R18 Anniversary Edition
At the 600 mile service, I asked the service manager if they would adjust the idle up from 900 to 1100. He said the bikes idle could not be changed. This seemed odd to me as many of my bikes in the past were idle adjustable.

Was he just saying that BMW does not want their service techs to do this? or was he saying that no one is capable of doing it? I fussed and told the manager this seemed quite odd.

Also at the 600 mile service, I brought along a different back wheel and asked them to remove the existing wheel/tire and swap the rubber to the new rim. The service manager said BMW would not allow that. I said WHAT!?

Come to find out that they only change rotors if new bolts are used. So I ordered new bolts and left without the wheel swap. Ended up doing it myself in the garage using the new bolts. But the old bolts look fine. I used a wire wheel to remove the old locktight........the bolts are quite reusable.

This has been discussed on various forums for years. BMW has spec'd "1 time use" hardware for many years, but they don't appear to be this way due to being a "stretch" design rather they are coated in a "micro" thread locker. With an undamaged bolt being properly cleaned one should have no problem doing as you did. That said, if in doubt it is very few $$ to replace them if in any question as to their being reused.

The idle and tunes in general are all part of meeting todays crazy lean emissions and OEMs are very restrictive and locking components that not long ago that allowed tinkering. Is it just in one mode or all that you are concerned with? You can spend $ for aftermarket tuning and there are thread comments on the forum that may help you deciding if you want to pursue that avenue. These things will idle low and be just fine and there is enough flywheel effect-torque that even at idle speeds in the 8XX RPM range one can simply ease the clutch out without adding throttle and she will happily start you on your way. Basically if it just "seems wrong" rather truly having a problem (Rock is much more loping than Roll or Rain) I would ignore it and just run her like you stole her.

Lastly, If you have a gs911 or similar tool you can reset the adaptives and see if that helps. I find the few minutes it takes to hook the tool up and do a "quick tune" never hurts and at least in my mind I always think things seem to be in their happy place when I'm done.

Good luck 🍻
