Anybody have handy the torque specs for the smaller (modern) sprint variator nuts and clutch nut?

Have you removed them yet? Put a sharpie line through the shafts and nuts, When you put it back together, go slightly past the line. My 50cc Yamaha calls for 25ftlbs on the variator, and 30 on the clutch. Another option is to take your torque wrench and test for spec before you dissamble. Set it at 25ft lbs, try and tighten down the variator nut. Does it click before you move it? If not, set it at 30, and so forth.
