I need clutch school (101)

[TRUE BLUE SINCE 1980]

Can someone explane in simple terms how, springs , weights, rivets, rollers and gears and r.p.m.'s work together....
Here is what i have . On a e.fi vector ltx, I see the belt is only coming 5/8 to 3/4 inch to the top of the primary clutch. On My Apex the belt runs about 1/4 to 5/16 to the top.
The sled runs 104 on the dream-O-meter @8500 rpm. all stock, no studs, Gears are 24/39
I'am trying to squeeze out all that sled can give (on the cheep) , been asking around all summer and have heard; springs, rivets, gears.

I saw on a dyno sheet of this motor, 8500 is on the back side of the power curve.

REAL CONFUSED,
H.E.L.P.

Olav Aaen's clutch tuning handbook. But, if you've got a stock motor & clutch, check for new; & correct belt; how many miles on clutches & lastly check center to center & offset. These Yami's come very well clutched. Alot of miles can wear parts down & change rpm's...
