- Avoid jumping off of curves.
- Too much weight on scooter can damage shocks bend or break the frame.
- DO NOT ride on a flat or under inflated tire. This is dangerous and will damage the tire and possibly the wheel and could cause an accident.
Due to the ethanol additive in the gasoline we recommend adding a cap full of 2 stroke motor oil in each full tank of gas fill-up to decrease the hardening of gas lines and degradation of the fuel.
- Make sure all loose parts are tightened before each ride. (such as the neck of the handle bar, wheels, seat post, brakes, exhaust manifold gaskets and ESPECIALLY engine mount screws)
- Make sure tires are well inflated.
- Using the headlight, electric start and alarm (if applicable) too much will drain the battery.
- Gas scooters do have the ability to charge itself but slowly. An optional charger can be purchased for $25 at any local automotive store.
- Most new scooters would have a full charge and it would be displayed on the battery gauge. But in time, the battery can loose their ability to hold a full charge. That’s normal!
- Sometimes charging the batteries too much even when they are not low. Most of these batteries charging cycle are around 250-300 times.
- Winter and cold weather can drain batteries quickly. If it is parked outside in the cold cover it and put a drop light or leave a lamp near the motor. Putting a piece of carpet under the bike whether it is inside or outside will help in colder weather.
- If you store your scooter away for a long period it could deplete your batteries power as well. If the battery power drops beyond a certain point, the charger would not recognize it. Sometimes you could jump start the batteries by using a higher Amp charger.
- Brakes can be tightened by the handbrake area by the handlebar or by the rear wheel area.
- The cause is lack of oil getting to the piston and needle bearing areas. Certain oils can’t
cling on when the engine gets too hot. As a result, the needle bearing falls apart inside and
causes the engine to cease. You can buy a new engine or try to rebuild it. Be sure to always
maintain proper engine oil levels to help prevent this from happening.
- Ok there is one thing that has occurs once and a while. The fuel gauge could have been cross wired. Take a Phillips screw driver and remove the 2 screws holding the instrument cluster to the handlebar. Remove the speedometer cable nut with a needle nose pliers carful not to let the nut slide down the cable. Now turn the cluster over and take out the two screw out of the back of the fuel gauge and pull the gauge out of the sleeve. You will see either 3 or 4 wires on the back of the fuel gauge. One wire can go to a light and does not have a screw attaching it to the fuel gauge there may be some glue around the wire. One wire is black do not move this wire. That will leave 2 more wires. Unscrew these 2 remaining wires and switch their positions and screw them back in. Before you attach everything back together turn on the key and see if the needle moves now? If this has solved the problem screw everything back in the reverse way they came out.
- Make sure to squeeze the left handle brake while pressing the electric button.
- If the electric start makes a clicking noise, it means your battery is low or weak.
- Check the fuse.
- Is your key switch good?
- Is the electric start giving out a burnt smell? You might have a burnt out electric start. Sometimes there is no smell.
The small gold screw on the side of the carburetor is the idle speed screw. This screw controls the idle speed, the tip should extend about an 1/8 of an inch (4 mm). Adjust it so the engine will idle at just fast enough speed to stay running.
The brass color screw located lower on the side of the carburetor next to the choke lever is for the high speed mixture. Start by turning this screw in (clockwise) until it stops. Don’t turn it in tight, just until it stops. Next, turn the screw out two full turns (counter-clockwise). This is the factory setting. You should be able to start and operate the scooter with this setting. Once you have it running, you can fine tune. Never turn the screw more than 1/8 of a turn at a time. Try turning it IN about 1/8, this will help the top speed operation. BUT, turning it in TOO MUCH will cause the motor to run lean at full speed and can burn a piston. Also, running too lean will cause a loss of low end power. Once you get the mixture set you can adjust the idle, it should be low enough that the engine doesn’t vibrate. Finally make sure you have the choke lever down completely after the scooter is started and warmed up.
There is also a main jet adjustment screw dead center on the top of the carburetor. This is most always set at 1 full turn out. If this is not adjusted correctly, your scooter may not run, or run very poorly. Once again, turn screw all the way in (clockwise) and then out (counter-clockwise) 360 degrees (1 full turn).
- Check the gasket between the carburetor and intake manifold. It might be bad or maybe the carburetor came loose due to engine vibration.
- Adjust the screw with the spring on the side of the carburetor. Clockwise to reduce gas flow and counterclockwise to allow more gas flow. Bogging down is usually caused by too much gas going thru the carburetor.
- Give time for it to warm up. You may need a new spark plug. For your 150 cc Scooter we recommend a NGK C7HSA Spark Plug
- If that does not solve the problem, you may need to have your carburetor cleaned or you may need a new carburetor.
- Taking the carburator apart is not difficult, but you must remember to put everything abck in the same location without loosing any seals or washers. If you take the carburator apart took through all jets and ports. If you don’t see any light through the jets or ports then this is your issue. Simply clean the blockage and put the carburator back together. This is the issue with 100% of the scooter problems we see every spring. The scooters get almost 100 miles per gallon beacuse the jet that allows gas into the carberator is so tiny. This tiny jet is the reason this issue happens. When the scooter is not winterized propperly or ethanol gas is used this jet can get plugged up easily. By winterizing properly and avoiding ethanol gas you can avoid this issue.
