1. Now you can look for assembly instructions . which with the average Chinese scooter will be one sheet of paper which says something like attach the rear view mirrors. install the battery. etc. . You may have to use some ingenuity to figure out how to do all this. but it shouldn t be beyond the capabilities of any amateur home mechanic. It may help if you have a decent socket set. screwdriver set and set of metric wrenches since the supplied tool kit usually leaves much to be desired.

3. The fact is, scooters are like any other piece of sporting equipment; they can be used and used safely, but you need to take proper precautions. Here are a few easily digestible guidelines for scooter safety that everyone who uses scooters should observe:

   1. Always wear safety gear: Helmet, Elbow Pads and Knee Pads. This is a small investment, but necessary- only about $30- can instantly eliminate almost two-thirds of possible scooter accidents. In many states, provinces and regions throughout the world, these are required by law!

   2. Always ride your scooter during the daytime. When it is dark out, there are just too many things that can easily upset your balance and cause you to fall. Therefore, no one should ride scooters at night.

   3. Scooters are not toys! Children who are under eight should always be supervised when using scooters. Almost a third of all scooter-related injuries and accidents involve children under the age of eight. As everyone knows, scooters are capable of traveling very quickly, and children that age do not always have the judgment or coordination to handle these high speeds.

   4. Always ride your scooter Off-Road & Stay away from all cars and any other vehicles -Cars and scooters don’t mix, especially for younger riders. Smooth, paved surfaces are best – avoid bumpy, uneven, wet or rocky ones. Schoolyards, parks, paved trails are examples of safe places to “scoot”! Stay away from Sand, Gravel, Water and Dirt ¨C Try to keep your scooter on smooth surfaces.

   5. Always observe the basic rules of the road anywhere you use scooters. As scooters can travel as fast as many other types of vehicles, motorized and non-motorized, they too must observe the rules of the road. These include:

   -Stop at every stop sign. Look left, right, and left again before proceeding.
   -Stop at the end of the driveway. Look left, right, and left before entering the street.
   -Use proper hand signals.
   -Obey traffic signs and signals

   Not Recommended

   -Avoid jumping off of curves.
   -Too much weight on scooter can bend or break the frame.
   -DO NOT ride on a flat tire. This is dangerous and will damage the tire and possibly the wheel as well.

   Mechanical Tips

   Check all joints, hinges and quick releases to ensure the scooter is properly assembled. Stop using the product immediately if any joint, hinge, or quick release becomes loose. Correct the looseness prior to resuming the ride. Maintain proper air pressure in the tires. Low air pressure induces extra rolling friction, reduces ground clearance, and wears the tires quicker. If the brake lever touches the handlebar grip, stop use of the product until the lever is adjusted.

4. What the carburetor does is regulate the amount of fuel and air which are supplied to the engine. To go faster you need more fuel and more air and they must be in the right proportion. The fuel also has to be atomized as much as possible (i.e. be supplied in tiny droplets). The carburetor controls all these functions and generally does it quite well. Without removing and disassembling the carburetor, there are only two adjustments you can make, but these should take care of most minor problems. The first is the adjustment of the idle speed.

   Above is a picture of a typical GY6 engine carburetor and the view is that from the right side of most engine configurations on 150cc Chinese scooters. There’s a small spring loaded screw which adjusts the idle speed. It’s right next to the throttle control which is connected to the twist grip on the right handlebar. On most 150cc scooters, idle speed should be around 1500rpm when the engine is fully warmed up. Don’t make adjustments when the engine is cold. Take a 5 or 10 minute ride first. When the engine is cold the automatic choke is in operation and that can change the idle speed. If you have a tachometer, setting the speed is easy. If you don’t, you want to set the speed to a low idle. Fast enough so that the engine doesn’t stumble or stall, but slow enough that the clutch doesn’t engage and try to move the scooter forward. On most scooters from 50cc to 250cc, this will be somewhere in the 1500-2000rpm region.

   The other adjustment you can make is to the low speed fuel/air (“mixture”) ratio. This is done on most scooters using a screw adjustment on the other side of the carburetor as shown below.

   This screw changes the air to fuel ratio at low speeds. It shouldn’t need much adjustment, but the way to do it is to turn the screw very slightly (1/8th turn) and see if the idle speed goes up or down. If it goes down, turn the screw back 1/8th turn to where it started, then 1/8 turn in the other direction and see if the idle speed goes up or down. If it goes down, turn it back to where you started since you didn’t need any adjustment! If the idle speed goes up, continue turning the screw in 1/8th turn steps until the idle speed is at a maximum. If it starts to go down, turn it back to get the maximum idle speed.
