Check the gas tank for sufficient fuel if the scooter will not start. Refill as needed. Turn the ignition on and verify that the kill switch is set to the "on" position. The kill switch is beside the right hand grip. Squeeze the left brake lever and push the starter button. If the fuel in you tank has been sitting for longer than 30 days it should be drained and replaced with fresh fuel. Fuel can become contaminated if allowed to sit for extended periods of time and create difficulty starting the scooter.
Remove the spark plug to check for carbon deposits if the scooter has trouble starting. Place the cap over the plug. Hold the plug against the cylinder head. Push the starter button and look for a spark. If there is a strong, blue spark, the plug is good. Replace the plug if it has a weak spark.
Allow the scooter to sit for an hour if the engine has flooded. If the engine still does not start, remove the spark plug and crank the engine a few times to remove excess fuel. Replace the plug and attempt to start the engine again.
Check the tire pressure if the scooter runs too slowly. The pressure should read 32 psi when cold. Rotate both tires to see if the bike moves more freely. The brake could be adjusted too tight or the brake fluid reservoir may have been overfilled.
Adjust the idle speed screw if the engine idles but then dies. The idle screw is on the right side of the carburetor. It has a spring around the threads of the screw. Turn the screw one-half turn clockwise to increase the idle speed.
Remove the front cowl on the scooter to check for loose wiring if the turn signals are not operating correctly. Inspect the wiring from the turn signals to the wiring harness. Check them for tension and tighten as necessary.
Check that the carburetor and intake manifold are securely connected to the engine if the scooter is hard to start. Inspect the gasket or seal between the manifold and carburetor. Replace the gasket if it is damaged. This could be the cause of a leak in the system.
