I have a USA 2020 Super 8 50x, it was getting right at 25mph flat when I got it. I pulled the CDI pink wire and it started getting up to 33/34 mph flat & downhill. I just changed out the variator boss from the shouldered to the unrestricted (they were both the same length 38mm), and afterward I am still getting the same max speed, only now it seems like it's taking longer to get to 33/34. It has the stock variator with the factory 6.5g rollers and I am about 6ft, 230lb. What could be causing this limitation that would make removing the variator boss restriction have no effect?
