How to Troubleshoot Your 150 CC Scooter

Troubleshooting a 150 cc scooter such as this one can save you money.

Many simple components of a 150 cc scooter can malfunction causing the scooter to underperform. Being able to quickly troubleshoot potential problems with the scooter's system is an excellent way to avoid costly mechanic bills. Performing a simple troubleshooting procedure any time your 150 cc scooter acts strangely is a necessary process before opting to take your scooter into a licensed mechanic.

Instructions

1. Turn your key to the "On" position to check your gauges. Many 150 cc scooters have console gauges that indicate levels of various elements of the scooter, such as fuel, mileage, speed and even oil temperature. If any of these gauges do not shift when you turn the key to the "On" position, you may have a problem with the electrical system of the scooter.

2. Check the tire pressure of your front and rear tire with a tire gauge. For 150 cc scooters, the front tire should be at about 22 psi, and the rear tire should be at about 29 psi. If either tire is underinflated, your scooter's speed will be adversely affected. If either tire is overinflated, your scooter's handling will be impacted.

3. Tighten all visible bolts with a socket wrench on the top and bottom of your scooter. Visible bolts are most likely to loosen because they are exposed to elements including rain and bouncing rocks. Loose bolts, particularly on aesthetic paneling, can often cause the scooter to rattle during operation, giving the scooter the feeling of having a severe mechanical problem, when in actuality it is a simple issue of a loose part.

4. Check your scooter's battery with a voltage meter. Access the battery compartment underneath the seat and attach the red (positive) gauge to the positive terminal and the black (negative) gauge to the negative terminal. The meter should read approximately 5.85 kilowatts.

Tips & Warnings

• Review the maintenance records of your scooter, particularly dates of oil changes. Change your scooter's oil and oil filter about every 1,000 miles.
