I installed the Malossi variator on my People 50 2T with recommended 5gr rollers and Malossi purple torque spring. I experienced the same, probably worse, wanted to rev to the moon, top speed way down. I installed the 9gr rollers that came with the kit and put the OEM torque spring back in and works about perfect for me. The People 50 2T is down on power compared to my Super 9 LC, so bear that in mind. CVT on People has really nice performance from dead stop, not too busy, just right.
On my Super 9 LC, I installed Dr Pulley 6.5gr sliders, with red fly springs and yellow torque spring that came with the scooter when I bought it used. I also installed the Malossi torque controler. I tried the white torque spring that came with the kit and was too stiff, wouldn't move out of low range gearing. I don't like the red fly springs, too busy on take-off, but otherwise CVT is working great, very nice operation. I baby it from dead stops or clutch gets hot and slips too much, but once gets going is very sweet. I am waiting for OEM fly springs and plan to swap out the red ones.
I wasn't going to buy another Malossi variator, but I got another one after you posted the good deals at ScooterWest. I bought the variator and the BBK for AC. I plan to put the BBK on my People and will put the variator on my Super 9.
Based upon my limited experience, I think the Dr Pulley sliders with OEM variator work about as well as Malossi variator with rollers. I bought 3 sets of Dr Pulley sliders 6.5, 7, and 7.5gr. So far I tried the 7.5 and 6.5, but will probably try he 7gr too.
It really steps up performance when you get the CVT dialed in.
