I'm just curious:

Given that the K1100 engine has a spin-on oil filter, does anybody know why the filter is located behind a sealed cover in a chamber where oil flows freely?

The great advantage of spin-on oil filters is that they can be mounted externally on the engine without the need for any kind of cover, usually making filter replacement extremely easy. This thought goes through my mind every time I change my bike's oil and I have to go through the mess of dealing with the oil filter's bolt-on cover.

Like I said, I'm just curious...

The BMW filter being behind a removable plate gives the Germans extremely high marks vis-a-vis the Italians who (on the Guzzi 850) put a screw on oil filter inside a cast crankcase sump WITH A DRAINPLUG on the opposite edge of the sump case. Unless you knew it was there, you would never remove the crank sump to drain the oil and thusly "discover" the filter's existence.
I found this out by buying a basket case Guzzi with a bad engine. Said engine was suffering from a burnt bearing due to an old filter plugging, blowing its gasket neatly inside the sump and then spewing the pressurized oil out and back to the sump instead of the crank bearings.

IOW: count your blessings! at least the Beemer people gave us a clue with the drain plug and hatch cover!

That's a good question, I just went through that messy procedure this weekend. Maybe it's done in the name of engine compactness. Could you imagine an oil filter hanging out of the block? It would mess up the shape of the belly pan for sure!

I'm currently watching a documentary on BMW and they went from the history of avation production right to the automotive production without even a mention of the fact they made motorcycles before they made cars!

I guess that what's I get for watching CSNBC!

There are more than a couple engineering items on a K bike that I look at and think......WHY??

Let's not even talk about an engine design where the cylinders point downward while on the sidestand

I've seen an 80's K100 at our local classic bike club with the stand stand moved to the right habd side.

The bike is in a tatty state, the engine was full of rattles.

Maybe missing out on pre-start lube for many years is the culprit.

The filter in the crankcase isnt a hassle for me, I'm so happy I can buy a standard car filter rather than an epensive custom size specific to the model.

It would also be nice to have an access plate on the drive shaft casing and a grease nipple on the spline so that you could grease it without taking half the bike apart.

Don't know if you have many Seat cars there. I got a 1.4 3 cyl diesel recently. The oils filter is in a 'cup' with lid in front of the engine.
So just screw off the lid lift out the filter drop in new one screw back lid. Job done.
No oil running down block etc. It's essentially a German car as VW own Seat.
