A slipper would be frickin' awesome! I'm running an EBC clutch and coated steels from Kenny. Great service from them so far.

I was asking about what year model clutch are you using? They have different stack heights, early vs late.

Also, I'm guessing you are not using that double-wide steel plate, correct?

I'm told the slippers being used in the DOHC's are good for several seconds faster lap times.  8)

Another benefit is spring pressures are not so critical - only need enough for the initial launch mainly.
Lighter clutch lever pressure and the harder the motor pulls, the tighter the clutch holds.

Sorry I didn't understand. I'm using late clutches on both bikes with the double steel plate in the middle and the wider tab friction at the front. Kenny felt that setup was the best route. I'm very happy so far.
All you gotta do is do what you gotta do.

Slipper would be nice especially when you start increasing compression. They inspire confidence.

Hi all,
Anyone ever make a slipper clutch work on a single cam bike?

I ran a locker for the last two seasons racing my SOHC sidecar.
The four post clutch took a bit of tuning.
As usual I broke a couple of clutches before we got it right, but once sorted it made a big difference to the bike.
The older I get the faster I was.
