Hilliard Inferno Flame clutch springs

4 Stroke Kart Engine Forum

Researching the web I’ve found comments like “most people run 2 black and 2 white springs” and such. Here in Australia our LO206 endurance class are mandated to run 4 white springs.

I’ll be driving a sprint class and so wondering how fellow US sprint karts behave with 2 black and 2 white springs. As I understand it, the full engagement will be at a higher RPM than with 4 white springs.

Does that mean the whites make the engine chug whereas the 2 black 2 white will hook up closer to usable torque?

Note that we have some less flowing circuits than what I’ve seen on youtube of US racing.

I’m also guessing the extra RPMs of 2 black 2 white would wear the clutch shoes quicker?

Seeking to learn from the experienced.

Thank you.

Basically yes but the only difference is a few hundred rpm, and this only matters if you have slow enough corners (or standing start) that your clutch ever disengages. Otherwise it doesn’t matter because your clutch is fully engaged anyways.

Overall I’d prefer a fixed setup as it’s one less thing to worry about.
