Hi guys

I've got pictures of my K75 to post, planning on doing that tonight. Hope you are all well.

I've finally got my 92 K75S back from the shop and am in the process of fixing the other issues. I'll post an update on my other thread shortly. My question today is regarding the clutch. I'm having a few problems:

- Shifting up from first to second, I would say 1/3rd of the time I get stuck in Neutral and have to really kick it.
- Shifting down from 3rd to 2nd when the bike is moving is a struggle. I hear gears hitting against each other and I have to bear the sound of it and really whack down or wait till the bike has fully slowed.
- Shifting down from 2nd to 1st when the bike is moving, does the same thing as above.
- Occasionally shifting up between 2nd and 3rd, I hit some sort of weird neutral ground, where my gear counter goes blank and its seem I'm halfway between the gears.

I'm quite a bit worried because its really quite a pain in the ars right now. I'm going to try adjusting the footlever and maybe tighten up the clutch cable a bit? What are some thoughts on what it could be?

There's really nothing to adjust on the foot shift lever. The slot should be aligned with the mark on the shaft.

Proper clutch cable adjustment:

Adjusted the clutch cable - no real change. Still a horrible grinding from second to first and inconsistently shifting from first to second.

Transmission fluid recently changed.

Any ideas?

We're talking about the clutch spline lube as detailed here http://www.ibmwr.org/ktech/clutch-spline-lube2.shtml ?

Yep thats the one, if it is getting stiff it will cause problems shifting gear.

When the last oil change was done what was the old oil like, clean? dirty?

Would be unusual to have problems with the amount of gears you do if its the box its self unless you have bent/damaged the selector shaft.

Dry splines usually cause sticky downshifting, not grinding gears. And the sticky downshifting usually manifests itself in higher gears.

Maybe this'll help if your transmission isn't shot: http://www.k11og.org/tech/k11tech_shifting.shtml

I don't know if the K11 uses the same parts but on the R11's the main probs with shifting can be bent selector forks. This is probably due to mis-shifts before which can bent/damage the forks and lead to premature wear.

When you change gear the fork may not be able to get the gear wheel far enough accross for a clean change. Selector fork wear on the R11's shows up in small alloy particles in the gearbox oil, more easily seem by shining a torch in the oil. The R11 forks are alloy base with a hardened coating. Once the coating wears then the alloy is exposed and this wears far quicker.

Obviously if you remove the box for a spline lube 1st but the oil change can give you some idea.
