Important !
Engine Minarelli stock 50cc, under the cover of the variator all stock. The front variator is refined because the tracks of the rollers were limited, and the rollers rested against the walls of the variator. Rollers 3.8 grams Belt 751 * 16.5 Sleeve bushing, but there is a washer 1.5mm because this belt does not fall on the bushing.
And the most important thing is why it was not possible to achieve the maximum speed of vise 90 kilometers per hour, and the output of the drive belt to the maximum radius, because I do not have a suitable belt, I believe that in my case I need a belt 752 * 16.5 it will be perfect.
Because the belt is 753 long, and the 751 belt is short, and a little bit is not enough for the belt to go to the very edge of the variator.
The width of the belt in my case is 16.5 because 16mm slips, slips.
My case it means that I changed the front variator, in the factory version, you may need other belts, rollers, and more.
I was forced to change the structure of the front variator as shown in the video, because it is limited from the factory, and made so that the belt does not go out at full radius.
I will buy a belt of 752 * 16.5 so in my opinion, it should ideally fit, and work as expected, and maybe I will also put a tighter spring driver, my own spring seemed soft.
I do not know, maybe the previous owner of the scooter replaced something under the variator cover, and there were not installed at all native components, therefore, it turned out to be so difficult to adjust the transmission.
