K11 Owners Group

I've been some time doing some research on this, through a couple of independent BMW specialists.
OK here's what I have.

The K1100 / K100 frames are identical with the exception of additional brac ...

The frames are not identical. Does the fact that they have a different part number maybe give you a clue?:

Interesting, what are the part numbers

By the way, have you ever seen a K100RS4V (BTW, ...

The only difference between the K100 16V, and the K1100RS, is the extra 100cc.
In every other respect, both are the same bike, WITH IDENTICAL FRAMES, and as we see, the K100RS 16V does indeed have th ...

It's not the same frame. As noted earlier, on the RS part of the frame is the lift handle. On the LT it's a swing out lift handle like 2V Ks.

You can see the lift handle as part of the RS frame in ...

Don't assume there is a problem.
When I had my RS, I noticed that the fan didn't cut in till the needle was a hairs breadth off the red.
This is quite normal apparently.

OK I'm confused. I don't lean anything considering how heavy the thing is.?

I tend to do it when it's on the centre stand.
If you don't have the strength, then yes, don't attempt it.

I don't ...

These bikes hide oil - somewhere, somehow. You can stop the bike, centerstand it, check the oil - and there might not be any showing. Next time you ride it, stop and centerstand it, it might be back u ...

It lasts for about 30 seconds, only on cold starts.
Not once engine has been run for a while.
I can't seem to isolate the source, but suspect it coming from the exhaust.
Is this normal ?

I recently sold my K1100RS to buy an LT instead.
I just got this email from the chap who bought it from me.
Could have been very nasty.
Thankfully he's OK.

"Please check and replace all you ...

When was the last time you cleaned it out? Changed the coolant? Considering the tank hold 20 or so ounces, how much goo was in there? Enough to see in the site gage?

There was brown goo sitting in ...

Of course it may have been there for some time and nothing to do with either places. However if it is at the bottom of the expansion tank it will not be oil! Oil is lighter than water/coolant and will ...

K1100LT
I found some oil settled in the bottom of my expansion tank.
Removed it, poured the contents into a jar for a closer look, and yep, definitely oil.
Blown head gasket ?
Sad

PS
No overheat ...

As I stated in my initial response, I'm pretty sure that it is possible, I just don't think it's worth the time/money/effort.

I'd rather be riding than wrenching. (Although I'm sure many here don ...

I was going to say also that the LT has the swing out lift handle that the RS does not have...minor, but still a difference.

Actually, some European model RS's do indeed have the handle

In fact, ...

Don't know what research you did but the frames are not the same.

They are in fact the same frames, but with slight differences, to accommodate the different clock arrangement, hence the different ...

Pretty much none.

The LT also has slightly different main frame geometry..

Been investigating, and it seems that the LT and RS share the same frame with no differences, which also goes for every ...

Just wondering, how much of the LT fairing subframe is shared with the RS.
Basically, I've been offered a whole set of RS bodywork cheap, and fancy doing the conversion.
I swapped my RS for an LT, b ...

I had my bike on the dyno a little while back, and the tester noted that my speedo starts gradually under reading from 30 mph. By the time it's showing 70, the true speed is 61.
Sad

It's interesting to compare the primitive ABS 1 system used in my K1100RS, and that used in more modern bikes,
On the R1200S I once owned, getting the ABS to cut in on the front was very hard, (good ...

Good luck with the new engine!

Well, the new engine has just gone over 1,000 miles and is running sweetly.
This was confirmed recently, when it went on the dyno, and got a thumbs up from, the tec ...
