What is stopping a lot of us from going ahead are the sanctioning body rules....Given that the ZX7 appears to have been the first sportbike marketed with a slipper clutch - in 1988/89 - no body I know of will yet accept slippers in forgotten era/pre 82 or whatever name it goes under where you are....

You should really confirm the spline interchange with Agemax. If they are tha same all it means is that the late GSXR600 clutch hub is a starting point for a slipper conversion. I can confirm that the GSXR1000 spline is quite different to the early GS's.

Agemax, I believe that at some point in the past you posted that the retaining washer for the gearbox input shaft is the same part number for all models, indicating that the splines are the same for the different motors.

If someone has a part number for that one it should give a pretty good indication of how many models use that spline.

Dose someone have an old clutch from a 1000 that they would be willing to donate or let go for a reasonable price? And are the clutch specs the same for the 1000-1150?

i replaced the clutch plates on a Aprillia RSV Mille yesterday. the slipper clutch design on that bike is so simple and would be an easy mod to do on any GS with a bit of machining.
as long as it has the "pushrod through the shaft" set up, rather than the actuator in the clutch cover.
i am toying with making one for my GS1000, as i have the hydraulic clutch conversion so there is no actuator in the cover itself.1978 GS1085.

it works by vacuum. a big diaphragm is bolted to the centre of the clutch pressure plate, on the release pushrod. the end cover is sealed with a tube attached which connects to the vacuum ports on the inlets.
when you throttle off the vacuum in the inlet tracts pull on the diaphragm and disengage the clutch just enough to allow it to slip slightly.
sounds too simple but it really works1978 GS1085.

I am back stateside and have made more progress on this clutch, here are some photos I took today.
I must now machine the backside of the slipper cam as well as the inside of the hub to get the retaining nut to thread down all the way, then I can machine the back of the basket to have the correct spacing from the primary drive gear.
