I just pulled the variator cover on my 2012 Like. The scooter has about 1500 miles on it. The first 1000 were kept to under 40 mph. The stock rollers had quite a bit of wear. Every roller has flat spots. I weighed them on a digital scale. They came in at 13.8 grams. The paper variator cover gasket came off in pieces. With all the air inlets on the cover, I'm not sure why there is a gasket there. I will probably clean both surfaces and put it back together with no gasket. I am replacing the stock rollers with Dr. Pulley sliders. I have a Yamaha C3 with sliders in it. They have over 12,000 miles on them. They are showing minor wear, and have not lost a bit of performance. In my opinion best upgrade you can do.
Can someone please give me a torque setting for the variator nut? The free manual I got online tells me 93.1 N-m which is over 68 foot pounds. This seems excessive by about 20 pounds. If someone can help me out with a number, I would be grateful.
