Hi to all:
wanted to give you an update of the job: installing heated grips and hand guards.
Parts that I bought:
Heated grip kit: PN 61 31 2 300 383. All instructions and wiring/switch for installation came in the box. 317$ from BMW of Chattanooga. Max BMW wanted over 500$.
Left and right hand guards: PN 32 71 2 315 711/712. 46.30$ at the local dealer. Perfect fit for the 75S
Brake reservoir cover: PN 71 60 2 315 713. 11.22$, also local dealer. Perfect fit as well.
The installation would have been much faster if I had realized that the handlebar was predrilled already for the kit. In any case, it took a few hours, and allowed me to learn a little about the machine while removing and installing the handlebar for no good reason.
A few pictures below to complement the posting. I believe the thing looks OK, and hopefully will make spring riding more comfortable.
Also, if anyone wants a scan of the installation instructions, please pm.
Hope this info is useful.
