But with all the repetitive clutch questions, I never saw an answer. My 1981 850G slips on a somewhat hard pull. Normal riding is OK. It seems a bit abrupt when it disengages, a very short throw. I pulled the clutch cover and stuck a standard 1/4 inch washer on all 6 springs. I don't see a lot of difference, and my question is, did I do much to the spring tension or just waste my time? I'm trying to figure whether I need new springs of plates.

New springs will probably fix it. The plates don't wear much unless they are slipped a lot, but the springs hav been under compresssion since the bike was built. They are almost certainly shorter now. I'd go with new Suzuki springs, while you are in there measure the plates, if they are within limits put it back together and ride. If they are too worn replace them.

What motor oil are you running in it?

[wymple]

15-40 diesel at the moment. I've tried several, Rotella, Trop Arctic, motorcycle specific blends, all no help. I use 15-40 quite a bit, in real hot weather I may run 20-50 Castrol. I jump around on oils, and change my oils a lot.

A 10w-40 Rotella is good enough whether it is the conventional or synthetic. I run a 10w-40 full synthetic with NO problems. Really no need for a 20-50. I would also suggest not jumping around on oil brands, find one you like and stick with it. Tkent is probably right on the clutch springs. You can either order stock springs or go with the EBC HD, I went with the EBC springs and like them very much. Much better then the springs I had, which turned out to be Barrnets HD springs. You needed a gorilla grip for those. When I went with the EBC springs it was much much better. EBC says their springs are about 15% stiffer then stock. I would also pull the plates and check them out and see what wear is on them as well.

That could be part of your problem.

Pick one and stick with it.

All of the oils you mentioned (and several others, I'm sure) are worthy of being put in your bike. However, each one of them has a slightly different additive package, and there is no guarantee that those additives are totally compatible.

Without knowing more about the clutch itself, it sounds like it is just an adjustment issue.

Have you pulled the clutch pack yet to examine the steel plates and fibres? Have you measured the spring length?

Even just pulling the clutch apart and cleaning up the plates and discs can result in improvement, but you need to know where you stand first.
