There are a few tracks i run where a disc clutch is allowed ... Getting tired of be beat on the restarts because of my drum clutch ... What bully disc clutch should i get for my clone running akra medium
this one.^^^^^2 disk 6 spring.
Are you sure you have your clutch slipping at peak torque on the starts?

best way I've found to determine best clutch stall RPM is this.No im not sure ... Ive just got my kart to handle well im faster than most of the karts ive raced once i get going ... Just takes a lap or two to regain what I lose on the start and restarts my stinger is older i got it used 2 years ago so now as far as kart tuning im down to the grit .. The clutch ... Im running on dirt tracks if that helps you guys with any suggestions

Put a bathroom scale between the front of your kart and a strong wall. At full throttle, the best clutch setting, rpm wise, will be the one that produces the highest reading on the scale. Don't forget where you heard it.

when I first switched from a centrifugal clutch, (Burco) to a disk clutch, (1977) I felt no difference on the low-end, but it was better on the top-end.
If the disk clutch is better off the turns and the starts, it can't be by much. If the clutch is holding the engine at peak torque, and that's important, it's transferring that torque through the chain to the axle. Unless the shoe clutch is creating a lot of heat, a power loss, there should be no difference off the turns, disk or drum.
if you've read Muller's article, you might want to use the clutch with the heaviest shoes and strongest springs.

do you know your stall RPM? Have you tested it with a bathroom scale? If your clutch is slipping at peak torque on the starts, you'll get your best, "take off". If you do the bathroom scale trick, and are 100% certain that the stall RPM is at peak torque, and it still feels sluggish, maybe you do need a disk clutch. But even if you have a disk clutch, if it's not set to peak torque, you're still going to feel sluggish off the start.Im just looking to get a better take off just seems very sluggish off the start
