Clutch discs are still "slipping"

[santhyago]

Can you tell me if this behavior is regular?

I've already replaced clutch disks to Barnett and the coil to a better one.

It looks like the clutch discs are "slipping".

How can I fix it?

Add in the retainer spring. The stock spring is actually pretty light compared to how much HP and TQ the Vmax puts out. In my opinion, this should be one of the first upgrades, especially since youve already changed the fibers. Now, that being said, did you measure everything as it was going back together? With stock discs, if the pack is too thin, you can buy thicker steel plates.

also I had slip when using yamielube . I switched to rotella 15w40 and that took care of the slippage
