K75 Transmission Problems???

[paulsibek]

At the open house of the new Ventura BMW, another K75 owner told me that they typically have transmission problems at about 60k miles.

He said that they begin to jump out of gear initially and this is typical of the breed.

I've never heard this before and doubt the veracity of his statement, but I am asking any of you K75 guru's if you've ever heard this????????????????

My K75 jumps out of first or second once every two months. I think it's because I don't have it in gear all the way.

Paul,
The K75 uses the same transmission as the K100, K1100's. No, they do NOT
begin to jump out of gear at 60K unless they are broken or abused.
:brow
I know of several K75-K1100's with upwards of 150K with no transmission problems at all.

heard anything about this here and figured that I would have.

Perhaps this person is an abuser thinking that because his K75S looks like a racer he can treat the trans like he's on the track.

Whadever...

Perhaps I should not be talking about things in which I really do not know of for certain. However, at around 80 thousand miles on my K75 I noticed my bike seemed to be slipping out of gear. I knew it was time for a major service and spline lube. I had a dealer do that and it really did the trick.
I am curious to know from any of the more knowledgeable people out there if a spline lube would have anything to do with that? And seeing that I had a service II done at the same time perhaps it was something else that was done during the maintenance.

Dennis,
An Input shaft spline lube (where the clutch disc rides on the tranny input shaft) CAN affect shifting, especially downshifting.

My K75 transmission is starting to grumble a little bit at 184,000 miles. Its never been apart.

Hi Jon,
I'm sure Paul or Voni will chime in if they see this. They have about 300K or so on theirs I think. My K1100LT is right at 132K trouble-free tranny miles.

I have 362,000 miles on my K75 original transmission which has never been opened or repaired in any way. It does not jump out of gear. It never has.

I recently bought another K75 cheap. It had been traded in with a complaint that it was jumping out of gear. I bought it from the dealer before they even rolled it in the shop. I replaced the shift lever which had been bent in a tip over - and proceeded to do everything I could think of to make it jump out of gear - and couldn't.

They do require a full clean stroke of the lever - and lazy ankle syndrome or a bent lever at an awkward angle can easily cause them to not fully engage - but that is generally operator error.

Whenever I get the chance to tell some non-BMW, non-biker, that I have 108,000 miles on my K75S I usually get a response between awe and disbelief. Then I read thru this forum and feel like I'm just getting started.

FWIW, my trans has never been apart and still works more or less like new. Guess its good for another 254,000 miles !!!

O.K. now that the subject has been brought up.
Removed my K75 transmission today for a lube and found the splines weren't dry but had definite wear.
Is there a way to measure spline wear?
How much is 2 much before it's an expensive paperweight?
Shifting has never been great but learning to preload the shifter and synthetic fluid did help a little.
feeling a bit depressed now

Well, I'm glad to know that my tranny should be good for a while, seeing how my bike is still a baby with only 23,000 miles on her. I learned real quick not to try and shift my bike like a cafe racer, and I can honestly say that every missed gear has been my fault. But now that I've put 4000 miles on it I've become more used to it and hardly ever miss shifts.

One thing I've noticed about my bike that I haven't brought up is that sometimes it doesn't want to go into 5th gear. It eventually will, just not right away. I've learned that it goes into 5th easier and with more reliability at higher rpms, mostly 4500 rpm and up. As a result, I find myself riding around Tucson (most streets are 40-45 mph speed limit) in 4th gear at 4000 rpms, only grabbing 5th at 55-60 mph. Does this seem like normal operation? Or could it indicate a problem? I just had the splines lubed and a new clutch cable installed, and the shift lever is in good shape as far as I can tell. Any opinions?

:brow I would agree with Johnyquest, most shiifting probs are user errors. With one pair of boots I can miss gears, with a pair of steel toes or a boot with a bigger toe I never miss. Preloading the shift lever has helped me alot, and the few times that my K75S has slipped a gear it was not in in the first place. Thanks alot guys for the little tips and tricks along the way.
Peace :type
