Tail Cowl - Install Tail Rack
This is handy if you want to
drill holes to install a tail rack or drill a hole for
mounting the Audiovox CCS-100 cruise control in the tail
1) Remove both side/battery covers.
2) Remove the seat.
3) Undo the plastic knobbed machine screws in the back of
the tail cowl the hold the brake/tail light lens on.
4) Unscrew the two Phillips screws that hold the rear lighting
wiring harness connector to the back of the black "wedge."
5) On each turn signal, remove the Phillips screw that holds
the turn signal lens in place. Then remove the female blade
connectors from the turn signal socket terminals. Pull the
turn signal wires out from the rear.
6) Remove the little black plastic caps on the two nuts on
the bottom inside of the tail cowl. (If your bike still has
7) Remove the two 10mm nuts inside the bottom of the tail
cowl. The bracket those attach to may fall to the ground.
8 ) Remove the two 5mm Allen head bolts that hold the metal
bar for the rear seat hinge.
9) Remove the two Phillips screws on the front lip of the
tail cowl. The tail cowl and "wedge" can now be removed.
10) Remove the four 5mm Allen head bolts the hold the black
"wedge" to the painted part of the tail cowl. Do not
overtighten them when putting them back on as the material
they screw into can break free and you'll need to get out
your JB Weld to fix them.
11) Drilling holes to mount a tail rack (like the factory
tail rack or a Givi E181 base) is actually quite simple
because BMW molded perfectly positioned pilot holes into the
tail cowl when it was manufactured:
12) Using a 1/4" drill bit, drill a
hole through each of those spots so that the hole is
perpendicular to the surface of the "stump" that you're
drilling into. (So that the holes will be vertical when the
tail cowl is remounted.) Don't press hard on the drill in
order to avoid chipping the paint when the drill bit exits
on the other side. It is also helpful to put some tape on
the painted exit hole location prior to drilling to keep the
paint from chipping.
13) Next, try installing the rack to
make sure that your holes are lined up well. If they're a
little off, don't worry. Just use the drill as a router to
make any fine tuning adjustments on the positions of the
14) You'll want to do the final
install of the tail rack before you put the "wedge" back on
the tail cowl because it's much easier to install it when
you have things apart.
15) Installation is the reverse
mounting the 22 liter top case:
1) Sometimes, when mounting the
22l top case on the tail of a K, the mounting pin will
scratch the tail cowl's roundel. This can be avoided if you
put a small piece of dense foam over the roundel prior to
mounting the top case.
2) 22l top cases have been known,
on occasion, to fly off of the bike at speed. This can be
avoided by making sure that the mounting pin is solidly
secured in its "notch" when you rotate it clockwise to lock
the case on. If there's any play in that then it is
advisable add another washer under the inside portion of the
pin to ensure the top case stays on firmly.
