We get tons of questions from scooter lovers that need to do the fixing themselves, and that's great! Here are the top moped scooter questions we get most frequently:
Question 1: What's going on, my scooter isn't running really smooth?
Answer: Oil change? Almost always, this is the solution for rough riding. Oil changes should be done in the first 300 miles for a new scooter, and every 1,000 miles afterward. If you don't ride often, at the very least, definitely make sure you change your oil once per season.
Question 2: My front brake isn't working well?
Answer: If you've just recently bought your scooter then you'll need to pump the brake lots of times. After 1 or 2 days of riding, the front brake tightens up. If it is just now happening after you have had your moped scooter for awhile, then check the hydraulic fluid (it's the silver box on the right handle bar), and fill it up if necessary. Also remember, check for leaks on the break line, the connections, and make sure you have enough left on your brake pads.
Question 3: My chain keeps falling off, what's the problem?
Answer: Your chain may be too tight or too loose, or the chain is not aligned correctly with the rear sprocket. Use the axel adjuster to make the mandatory corrections.
Question 4: My scooter idles hot and doesn't run well?
Answer: Down on the engine next to the air intake is a screw with a spring on it that impacts the idle. That screw permits you to adjust the carburetor. Do a quarter turn to see if there is any improvement. Adjust as needed. More steps might be needed if this doesn't solve the problem, but that is the basic fix.
Question 5: If I remove my stock muffler and get a generic $15 to $20 muffler on eBay, will it make my scooter sound better?
Answer: Your moped scooter will still make noise; it will just be 10% to 20% less noisy. But remember, the disadvantage to doing this for new scooters, is you would have voided your manufacturer's warranty, which is a no-go if you ever have any manufacturer defects in the future.
Question 6: My Scooter isn't starting?
Answer: It can be for a number of reasons, but first go through this troubleshooting checklist to discover what the problem is. If you can't fix it, just take it into the mechanic.
A) : Confirm your gas tank has gas. Do Not put oil in the gas tank! Amazingly, this happens more than you would think!
B) : Check that the battery is connected, the fuse on the red line isn't burnt out, and the battery is fully charged.
C) : Check the spark plug wire and spark plug for a connection. Unscrew the spark plug and when you try to start the engine you should see a spark at the end of the spark plug.
D) : Try starting the engine with the kick start and the kill switch not engaged. Often times, the kill switch is bad. So go to the bottom of your scooter and unplug the kill switch wire, then try kickstarting your scooter (the kick start is next to the kick stand). Remember, before you try kick-starting the moped scooter, pre-fill the gas bulb ten or more times.
F) : If too many starting attempts have been made on the engine, there may be excessive fuel in the cylinder, or flooding. So definitely give it time for the fuel to run the lines, or remove the spark plug to permit fuel to disperse and then reconnect and try again.
Don't forget to prime the bulb by pre-filling the gas bulb repeatedly at least 10 times, and ensure you can see the fuel going in and filling up the bulb and then draining into the carburetor.
G) : If the engine starts after you prime the bulb but the vacuum is still not sucking gas, then you you will need to pressurize the vacuum. Pressurize the vacuum by taking the end of the vacuum that connects to the gas bulb, and use a device to suck on the line while the engine is running. After 1 to 2 pumps, gas will begin to come out (this is often times needed to re-pressurize the vacuum if you haven't driven it for a bit or if you run it dry).
If the vacuum line is sucking fuel, and you have no kinks in the gas line, and the gas line is making it to the gas tank then you will need a new vacuum. Make sure you prime the bulb and get the engine running without the vacuum to make certain everything else is working correctly.
