GY6 150 2000RPM Torque Spring

At 2000RPM you are going to a quick take off so to not loose any of your top end use 13/14gram weights in the variator along with other upgrades with at least 2000RPM clutch springs

Mostly using this set up a high performance clutch and bell are used also from either the NCY brand naraku or the higher end ones from Koso and Dr Pulley.

A Koso MKII Clutch with a Malossi bell with a NCY variator with 13gram sliders is a good combo for your CVT on GY6 150 scooters.

Now of course adding a DR Pulley clutch and bell does even more as well as variator.
