Since my dealer charges $85 for an oil change on my '07 GT, I decided to do it myself. It's not the same as my R bikes, so here's how it's done:
First, put the bike on its centerstand, position an oil collection pan underneath and, using an 8mm hex remove the oil drain plug located between two exhaust pipes:



Next, remove the last screw in the fairing on the left side under the kick stand so that there is room to get to the oil filter:



Since the normal BMW filter removal tool won't fit in the space, I purchased this oil filter tool from a local auto parts store for about $8.00:



Using the tool, remove the old filter:



Here what it looks like when the filter is off. Since the filter is side mounted, some oil will drip on the nearby pipes.



Install the new filter. Since you won't be able to torque the filter, be careful to avoid over-tightening. And since you install the filter sideways, you can't, obviously, fill it with oil before installation.
Install the oil drain plug (32nm) using a new crush washer.

The GT has a dry sump tank that must be drained too. Remove the tube from the top of the tank by depressing the ring that holds it on:





Then insert an old foam earplug in the end of the tube so that when you snake the tube down for draining, the oil won't come out until you want it to.



Here's the bottom of the tube and its connection at the bottom of the dry sump tank:



With the tube positioned over the oil collection pan, remove the foam earplug from the tube and let the tank drain. It will take about 20 minutes.



Since the engine and the filter drain their oil in front of the center stand and the tube from the dry sump tank drains behind the center stand, I use two oil collection pans:



Snake the tube back to the top of the dry sump tank and reinstall.
Fill the oil tank with three quarts, then run the engine, then add the other .7 quart.

Excellent, Rich. Simply excellent! As someone looking to get a new GT, ....Thank you!

I did not realize the new K engine had a horizontally mounted oil filter. I guess it was just too darn easy to mount it underneath like they used to be. $85 for an oil change? OUCH! That is certainly incentive to learn how to do it yourself. Nice job Rich. Thanks for sharing.

Thanks Rich

Rich, great pictures.....I don't have a centerstand....

PS. I don't use the small hose to drain the tank. I use a pair of pliers to release the clamp on the bottom of the large hose on the bottom and a piece of cardboard to direct the oil stream away from the pipes and outward to the drain pan... I have multiple oil changes under my belt. The first one I removed all the tupperware... Not any more!

Lets adjust the valves next?

Calvin,
Next time I'm going to take out the strainer in the oil filler and pump out the tank. I'll see how that works. I'm going to use this (Pela 6000 Oil Extractor):

Thanks Rich

Rich,

We met at the Spring '07 "El Paseo" in Dillsboro NC. I also met Calvin (with his K12S) at the Fall '07 "El Paseo".

First, I wish to add my thanks for your taking the time and effort to show us how you have done oil changes on your K12GT. Even someone as unmechanical as I am should be able to do an oil change, thanks to your instructions.

Second, with regard to the oil extractor, I understand how you can drain the main tank, but what about the dry sump?

I use an oil extractor on my K1200r Sport. it is quick!
I start the extractor, swap our the oil filter, drain the sump. Then I double check that I got all the oil out with the extractor. Put the oil in as discribed above.

Folkdancer48, unfortunely you still have to get underneath to drain the sump.

I really think it is quicker, cleaner and easier than doing the same on my old 1150Rt.

Cheers..
