While calibrating the gear position indicator, I realised that the shifter configuration (back to select first, forward to select higher-numbered gears) is 'backwards' compared to what I'd expect (and what I see in videos of other Prosports).
Is this a Kawasaki quirk, or did someone connect the linkage upside down on the gearbox?
That is normal, my Clubsport was like that (with the Kawasaki). When you fit a Busa engine, with the same linkage it reverses the shift pattern which is probably why the Prosports are the other way round
Both my clubsport (was) and PR6 (is) like that - pull back for higher gears.
It can be reversed but it makes much more sense to pull when acceleration is pushing you backwards then push when braking force is pushing you forwards in you seat.
Dunc.

When you say "like that", are you referring to my setup? Because what you've described is what I expected, but exactly the opposite of how the Kawasaki setup seems to work...

Hi Mike, apologies for the confusion. I'll rephrase it and hopefully it'll make more sense.
My clubsport (Kawasaki 1100) is forward for 1st then back for 2,3,4,5,6.
My PR6 (Suzuki Hayabusa) is also forward for 1st then back for 2,3,4,5,6.
The direction depends on how the linkage is not the engine type.

Hi Mike (@mikesmith), The Prosport I had (RMS0108) had the shift pushrod attached above the pivot point of the shifter so pulling the lever back would down shift and pushing forward would upshift. On the shifters I have seen for SR3 / 8s the pushrod was mounted below the pivot point on the shifter so pulling back is used to upshift and pushing forward is used to down shift. So it depends on if the pushrod on your car is attached above the pivot point on the pivot point (which it likely is) or below. Here is a picture of the shifter in my old prosport (the pushrod is disconnected in this picture), and also a picture of a shifter from an SR3 / 8.

@dunc - that's what I understood you to mean. My Prosport is the opposite; back for 1st, forward to go up a gear - same as Charley's observation.
On the bike, the gear lever pivots behind the rider's toe, so looking at it from the left side of the car/bike, counterclockwise to go into first, then clockwise to go up a gear.
You can see how that interacts with the shifter linkage here:
Pulling the lever back rotates the shift shaft anti-clockwise, so what I'm seeing makes sense.
The geometry at the gearbox end would make inverting the lever challenging, so I'm curious how this works on the Clubsport...
Are you saying that's how your Clubsport is set up? Seems simple enough.
I guess if the POs weren't too bothered about drilling holes in the floor tubes, why should I be? 🤣
Hi Mike, randomly found a pic of my clubsport (zzr1100) gear stick while looking for something else 🙂 My PR6 uses the same setup (gen 2 busa) but different metal work. Both are forward for first, back for all the other gears.
If you pivot from the bottom, it goes directly to the shift shaft. If it is pivoting from the upper mount, a bell crank is required to change direction. Either way will end up with the correct down shift forward set up.
I just modified the mount point on mine this week. hopefully the rod length wont be an issue, but it seemed easier and simpler than mounting a bell crank.
