Clutch replacement - drive plates only?

[longranger44]

So the clutch in my 82 750t has begun slipping a bit, only at high rpms under full throttle. As well as dragging quite a bit when cold to the point where the bike will stall if I try to put it in gear without letting it idle for at least 5-10 minutes, depending on how cold it is outside.

I pulled it apart and mic'd the friction plates, they are all within spec. The metal drive plates however are all out of spec when checked for straightness with a feeler gauge and plate glass. So my question is, should I just replace the metal drive plates? Or should I just replace the whole kit and caboodle, friction plates, drive plates, springs, etc? Is there any consensus on what the best clutch kit to buy is? I'm having trouble finding the correct oem kit. If anyone has the part number for the oem or another good brand I'd be very grateful

There are lots of opinions on this subject. Many say, use OEM parts where possible. I'm in that camp. OEM clutch springs for sure. For the steel plates, options are limited. Friction plates are more readily available aftermarket, but you need to hit ebay or similar if wanting NOS friction plates. My opinion is to stay OEM, or quality aftermarket, like EBC.

As well as replacing the clutch, drop the sump plate for a look at the oil pick-up. When the clutch has been slipping it's also been shedding fibres that block up the mesh on the pick-up.

First off, be sure not to use newer more modern oil with friction inhibitors, nor slick additives, these old GS clutches don't like that. No doubt if you can use OEM, you won't need to wonder about the quality of an after market. I've usually just replace what is out of spec or visually something amiss, My opinion and my opinion only, if I get a new fiber plate to replace a perfectly good fiber plate, you got the same thing only newer. For me, if clutch is slipping, springs for sure, if they're not sagging a little after 43 yrs. they should be. "I" wouldn't recommend HD springs.
