Back when we use to race, thats what we used, 2 disc 6 spring using the red springs...Bully

Put kart on stand and floor it, watch and see where your rpm is at, we adjusted ours at around 5450

Engagement 5450 ?????? That must be a Typo 3450 maybe ?, I can see Target max RPM to be 5450 and that's cutting it close with 5500 MAX RPM rule.

A general rule of thumb, is 3-4 teeth higher on your clutch driver for a Predator.

As far as engagement is concerned, 26-2800. Black springs, double weight

Well glad I kept my old notes

Went back and looked at them

We ran heavy class back then

We went up two teeth from 16 driver to 18 driver

Clutch engagement was set at 2825 with double weights with red springs (Bully Clutch)

Set gov, at max 5400 RPM on Kart stand

I notice you said you run Medium, I would still try to go up two teeth

Sorry for the confusion
