Detail Information

Power train Comparison Direct Drive Power train Engine axle rotation causes severe tire wear and a gradual widening of the gap between the fixed axle and tire surface. In addition to power loss and inefficiency, this design is highly vulnerable to water and dust contamination. Single-Step Chain Reduction Travel over bumps results in excessive power and traction loss due to the large difference in sizes between the engine drive and wheel sprocket. In addition, the chain / belt invariably comes loose or pops off. Viza™ Drive System Featuring a patented reduction gearbox, ideally matched sprocket and a chain drive, the Viza™ drive system delivers superior performance, driving safety and maximum durability.

Gasoline / Oil Mixture

Synthetic oils are the best to use in your scooter, along with a standard grade octane pump gas.

A word on engine oil: 32: 1 is the recommended mixture ratio. This ratio is dependant on the quality of 2-cycle premix oil used.

TIP: If using a high-quality synthetic oil such as Maxima Castor 927 mix at a 40:1 ratio for best performance.

Changing Transmission Oil

Remove the top nut from transmission, turn upside down to drain, add 180cc of 85-90w synthetic gear oil - available at most auto parts stores. It is recommended to change the gear oil every year.

Tire pressure

30 to 35 PSI

The rear tire tube valve is a little tricky to get to. The easiest method is to pull the valve over with a screwdriver and then thread on a valve extension (available at any auto parts store). Adjust air pressure as necessary and then remove valve extension.

Spark Plug Gap

Spark plug gap : .024-.028 inches (.60-.70 mm)

Chain

It is always use a good motorcycle chain lube such as PJ1 or Maxima Chain Wax.

Steering Column Adjustment

To tighten: Loosen small set screw on top nut, take big ccrescentwrench and turn nut clockwise. Be careful not to over tighten. Lift the front of the scooter off the ground. Push the handle bar in one direction or the other. It should swing freely. If it just stops and doesn't swing in one direction then back again it is to tight. To see if it is to lose: kneel in front of scooter, pick up front end of scooter by the fork with one hand, grab the steering column below the release post with the other hand and rock back and forth. You should not feel any play. If you do tighten as instructed above.

Carburetor Adjustment

The small gold screw on the side of the carb 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 black screw located lower on the side of the carb 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(ccounterclockwise. 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 an 1/8 of a turn at a time. Try turning it IN about an 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 (ccounterclockwise 360 degrees (1 full turn).
