Yes buy a 2k spring clutch, but use a STEEP-RAMP variator with SLIDER weights (I'd use 6g weights)

steep ramp variator? slider weights? please for an link... and why to use those? isnt 6g standard?

And which torque spring?

? 16x13 you mean D shape variator rollers?

Can somebody help me with a new problem? i installed new variator KOSO (10g less weight compared to stock) + 6,5g koso rollers, + red torque and clutch springs...

i dont feel that it would accelerate better, but i noticed a much lower high speed,... what should i do? i have a 72cc kit inside, and its not even 60% of that power....
