How to Adjust the Speed on a 150CC Gas Scooter

150 CC gas scooters provide a fun and convenient way to get around town. Unfortunately, as time goes on, these scooters often lose speed. Additionally, because they are technically motorcycles and not mere scooters, sometimes their speed can be too great for certain driving situations. Both scenarios require you to adjust the speed on your 150cc gas scooter. Though there are many methods for adjusting the speed of your 150cc gas scooter, the safest and easiest legal method for adjusting the speed is removing or inserting a speed inhibiting washer in the variator compartment.

Instructions

1

Remove the bolts holding the cover of your scooters variator in place. The variator is a part of your scooters transmission system. It looks like two large sprockets connected by a rubber belt. There will be anywhere between six to ten bolts holding the cover in place.

2

Remove the lug nut holding the toothed sprocket in place.

3

Remove the transmission washer from the peg that is connected the belt to the toothed sprocket to increase your scooters speed or add a washer to the peg to decrease your scooters speed.

4

Replace the lug nut holding the toothed sprocket in place.

5

Replace the bolts holding the cover of your scooters variator in place.
