How to make your 150 cc scooter start up speed faster ( Change Your Roller Weights )
( MY OEM ROLLER WEIGHT AT THE MOMENT 19G NEW ROLLER WEIGHT 10G )
this video is great for any scooter.
Remove the cover off your transmission to expose the entire drive train.
Next impact off the nut holding the variator on. ( impact driver is a must here ).
Once the nut is removed, remove the variator assembly.
The roller weights are located in the rear half of the variator under the ramp plate.
With the ramp plate removed, you can now see the roller weights.
Now is when you want to swap the weights with the new ones 6 x 10 g.
When you go to replace the variator, make sure the ramp plate is on the spline and pushed up against the toothed wheel behind the variator.
Reassemble the variator the same as it was removed then impact the nut back onto the shaft.
Any modifications you perform are done completely at your own risk and liability.
