Occasionally, very, very stiff into and out of 3rd gear.
Any thoughts?

How many kilometers since the last spline lube. Sounds like it may be due again.

Usually they tend to be sticky in more than third gear when the splines start getting dry. However, on bikes I've ridden third seems to be the most noticeable. If it hasn't had a spline lube in a while then that's the first thing I'd try. Can't hurt.

thanks.. for the moment I've changed the gearbox oil and added some slick-type stuff to see if that helps.
Spline lubing: Garry Webb who looks after the bike says 'not entirely necessary on late models'.. don't shoot the messenger!

Better to be safe than sorry, I do it on my 97 LT and did on my RS.
How is it when engaging first gear at a stand still, mine never makes a clonk or moves forwards unlike a lot of jap bikes.

Yep you got it, if it clunks into first then the clutch is most likely dragging, maybe from being stiff/stuck on the splines which might me the problem for third as well.

Beautiful, silky entrance into 1st, no clunk and no dragging.
I've put some 'slick' type additive in the gearbox and I have to say, after 150 miles, the gear change is very much smoother.
I'll see how it goes but so far no more stiffness.
Thanks for your help chaps.

Hi, Supercat1,
Yes, there are three spline areas - the clutch/gearbox input shaft, the gearbox output shaft/drive shaft, and the drive shaft/final drive. The ones which are the usual suspects are the clutch/gearbox input shaft and the drive shaft/final drive splines. The gearbox output shaft/drive shaft splines rarely give trouble. On the K1100, the driveshaft/final drive splines don't often give problems, either. The driveshaft U-joints and the paralever bearings DO, however, have the reputation of causing trouble.

I agree with Phil about the U-joints, I have just completed work replacing the output shaft dampers and found on stripdown that both UJ's were stiff and had to replace the driveshaft.
You could say there are 4 points to lube, the three as already posted and the joint between the two drivshaft sections too.

All the points on my LT showed signs of being lubed at some point but they were dry.
Be careful when reinstalling the driveshaft in the FD & gearbox, they have snap rings to lock them on and needed a good knock with a mallet to locate them but the FD end on mine was a real PITA, I think the ring was deformed as it would not seat right home, ended up swapping the ring from the old shaft.

There is also debate over driveshaft/joint phasing but its easy to do it anyway so I did it to be sure.

It is about a days work to do a full lube BUT worth it.

Rob
