GS650GL '81 clutch slips @ high load/high RPMs

I mic the steels and they are always withing specs. Test them for square on a piece of glass to make sure they are straight. With the 650 you have a clutch over designed for the bike since it is plenty large enough to handle the engine. But the wrong oil will contaminate the fibers. Mobile1 changed their formula somehow so I switched to RotellaT and it seems to be OK

Pay attention and write this down, which way your steels come out of the clutch basket; there is a flat cut side and a rounded side!

What does that affect? I've never heard a warning about that before. I thought it was just an artifact of the stamping process.

As a industrial machine mechanic for over a decade, it was my habit, and it seems just good practice to re-install parts in the same position and order. ie don't flip over, don't mix up the order, etc. And, thanks for the reminder, it's a good point. A Sharpie marker can be good to mark parts. We all know how memory fades after a month with the bike apart...or a week...or a day...or an hour...

"Now where did that go?" "Does this go in first, or...that?" LOL

I may have gotten the 'drive' and 'driven terms from the gears, but you've answered my Q about just changing the fiber plates, if the metal ones are within spec, and scuffing the metals.
