Clutch slipp

I’m using correct oil.
I guess I need to take out the friction plates and replace the springs....?
My question is, its better todo these to early then late?
Or can just do it when I «feel» it slips to much...?
Thank you for advice!

I've never seen stock friction plates worn below the limit. Brand new ones are not that far above the limit to begin with. The springs, though are often near or below the limit after 10 or 20 years.

No, opposite. The springs will sag from 40 years of being compressed. I'd replace the springs first and see how it works out. Grease the gasket so you can reuse it if need be.

2. Replace the clutch springs.
Do NOT not use heavy duty springs!! They will make it so hard to pull the clutch lever that eventually your clutch cable will snap. They are useless unless you have a heavily modified motor.
I’m running a 810 with almost every engine modification you can think of, and I’m running stock springs with zero slipping.
Hope this helps.

Maybe it depends o n the model? On my 1977 KZ650-C1 I replaced the friction plates because they were tainted with car oil that had friction modifiers that damaged them. After replacing the clutch plates I had zero slippage. That's my experience, but I guess other's experience may differ. I guess to be sure replace both the plates and the springs. Ed

It was not a issue last season as I can remember.
I will check the oil level, it can be its some higher then it should be.
When I got the bike 3-4 years ago it followd with a box with parts, it was some old springs in it, so its a chance that the springs has been checked.
I will check oil and double check the adjusment first.
If I overhaul the clutch next season, its:
Friction plates, 7 discs?

Clutch springs, 7 springs

These all the parts I need?
I need a special tool to get it loose?
