Yamaha C3 Variator restrictor removal " How to derestrict vox giggle fx50 " scooter transmission

I loosend all the bolts so I could give people that just wanted the quick process and how easy this is to remove, If you can change your oil you can do this. I also noticed that this washer does not keep the plates from hitting each other it actualy just makes the shaft the inboard variator plate rides on longer, with it installed both plates can be full compressed together manually.

I also drill lightend my weights from an original total weight of 36 grams down to 28. The stock roller weights are teflon ruber coated steel that has been compressed around a brass hollowed out slug.

The reason for doing this the final gear ratio comes on to soon fully droping your rpm by the time you hit 25ish I dont feel the accelleration again intill 35 this continues up to 43 where the stock limiter is set. By lightening up the variator weights this should allow the motor to hold a higher rpm until you get to ...
