Put a new clutch in it, that's about all that is going to fix a slipping clutch. If you want to go the cheap route and the friction pads aren't worn down completely you can throw an extra steel plate in the clutch pack to get a little more life out of it, but to me it makes more sense to put in a new clutch kit since you're going to have it all apart anyways, and add an extra steel from your old clutch in the pack when you replace it so you get more life out of the new clutch.

When a warrior's clutch starts slipping it usually isn't because the friction pads are worn out completely, just worn down enough that the pressure plate runs out of travel and stops putting sufficient pressure on the pads (sounds like a design flaw that yamaha never corrected).

well i've just think about something......i'm running castrol 10w30 car oils I'm not sure but are those cars oils are full of anti-friction additives....that would make sense that this oil is causing my clutch to slip....and I should switch to 5w30 next week cause i't doing aroud -15\-20 Celsius around here so it probably don't help...

Yeah, that can do it too. Some people disagree with this for whatever reason, but certain automotive oils do have friction modifiers and other additives that can cause a wet clutch to slip.

You can try switching to a regular motorcycle oil and see if the slipping stops, but there's no guarantee that there isn't permanent damage. Some of those additives are designed to fill in any kind of pits and imperfections in a surface, and they'll fill in all the pits in the friction pads making them permenantly smooth.

I'll try to switch oil. And then if it doesn't change anything I'll try another clutch I already have 2 spare clutch here all add a steel and change my spring by the same time I must remove my clutch cover to install my oil cooler anyway.

thanks
