They increase clutch engagement RPM which helps in two ways. It stops the kart from trying to creep forward at idle, and if you nail the gas from a dead stop the kart takes off noticeably harder due to higher engine speed at clutch engagement. And that's the part the grandkids like the best.
Just what I needed
These were exactly what my bike needed. The original springs were dead and these fixed the moving at idle problem and the mid-range flat spot in acceleration
You can't buy a better spring
