What have I done to my clutch? Transmission? final drive?

[SoCal_Michael]

When shifting I landed between gears but did not know it until I rolled on the gas. Probably between 2nd and 3rd. The bike made a gumbling noise and I shifted into a gear but the nioise continued when engaged. I shifted the other direction and the noise still continued. All the time there was no engagement or little engagement to power. After the tow home, I started her up in N and found the noise started as soon as I engaged the clutch and grew louder when I put it in gear with the clutch still engaged. It was hard to sift between gears. On the center stand I turned the rear wheel by hand. It turns freely in N. When put in gear, and the rear wheel is turned by hand, it is hard to turn but it will turn. It kind of brrrr's like a bicycle with cards close pined in the spokes. I am down heart about this. Any ideas on what has gone wrong and how to diagnose it.

How many miles,
1st thing to my mind with those symptoms sounds like clutch disk splines.

Agree a good bet.  Go to T tube and search for Chris Harris video of a K bike with striped clutch splines.  See if it sounds the same.

some 750 riders will tell you its the exhaust valve shims... dont listen to them... they are delusional...

is that a 93 k1100lt... if so... i do not know of any 93 and newer that experienced stripped clutch splines... with the limited info posted here im leaning towards the drive shaft... either ujoints or that rubber innards...

whats the mileage on that thing and what work has been done and when...

the best motobrick wrench in socal can be found in corona...

i would ring up lior... he can come fetch it if you caint get it to him... he will figger it out and treat you right...

I'm guessing either your final drive or clutch is kaput. If the clothes pin sound is coming from the wheel, it's the final drive.

Sounds to me like you've a failed driveshaft.  Not uncommon on the 16v K100 and '93 k11, especially if they've been taken out and not put back in correctly.  Best way to quickly rule it out is to simply pull the driveshaft and see (will be obvious, and probably look like this: http://forums.bmwmoa.org/showthread.php?34994-Drive-Shaft-failure-Options)

Thanks for the input everyone. The bike is a 93' K1100LT. It has 111700 plus miles on it. When I got it at 87000 miles, about four years ago, it needed a spline lube and some engine seals were leaking. I had the work done at Browns. At the rear end I replaced the rear shock with a Works Performance shock at about 98000. Of course a few sets of tires were replaced. After a while the transmission became harder to down shift and I had to rev a little with clutch in on some of the downshifts. It may take me a few weeks before I can remove the final drive to see whats what. Something I have not done and I'm a little nervous about.

Makes me think clutch splines are dry.

"It turns freely in N"  Probably not the final drive or drive shaft.  Possibly eliminates the transmission as a problem.

Just bought a k1100 in July. After 300 milles of summer riding I was gearing down on a long hill when all of a sudden it like a helicopter landed on my back wheel. By the time I got stopped it was clear to me that the drive shaft had broken. The bike is now at Beemer Barn Middleport NY.  New Drive shaft new clutch parts new seals motor and tansmission seals.... should be good for a long time.

Whoa!  :mbird    Please tell me that photo is from last winter!

Welcome wandering eye.  Looks like we're almost neighbors.

Yes Gryphon it is a photograph from last year...150'' of snow last. I rode my bicycle twice to town on our frozen lake 6 miles each trip. Lamenting not having photos of the RS to post here but will post an independent wrenchers report on the forum when my K1100 is repaired.  Tom
