Clearance with dry vs wet clutches

how do you know you are on the flats of the Allen wrench or on the high spots? In accurate measurement is highly possible. I’d use a round rod and bend it to the L shape.

Also you can measure anyplace you can get the gauge in there, it doesn’t have to be at the top of the snap ring. It can be under there on a friction disc, but use a flat feeler gauge so you don’t gouge the friction.

I like .100 with 5 frictions
.075 seems on the tight side.

do you need 5 Discs? 4 is plenty for most applications.

maybe you have pressure to the rear clutch in P or N? What is the valve body and the mods done to it?

I can rev to 3000 doing timing and they don’t creep forward.
