OIL AND FUEL
Engine Oil
The mini bike is shipped without engine oil. Fill with SAE 10W-30 Motor Oil. Refer to the owner's manual for the correct amount and grade of engine oil.
Caution: Do not over or under fill with engine oil.
FUEL
Never use leaded gasoline in this product, as it could affect the engine's emissions and damage the engine. The Mini Bike requires clean unleaded regular gasoline with a minimum octane rating of 86 or higher. Fill with gasoline up to the bottom of the filler neck.
TIRE PRESSURE
Check tire pressure. Incorrect tire pressure can affect handling, rider comfort, steering, tire life, and traction. Always check the tire pressure before each ride.
Tire pressure: Front tires: 10psi, Rear tires: 10psi.
Chain Tension
Check the tension of the chain. The chain (1) tension should be 1/2 - 3/4 in. (15-20mm).
Chain tension (slack) adjustment
- Loosen bolt (2) on the rear axle assembly.
- Adjust chain tension by turning the tension nuts (3). Tension nuts are located on both sides of the mini bike. Turning clockwise will tighten the chain; counter-clockwise will loosen the chain.
- Once the chain is at the correct tension, re-tighten axle bolt (2).
- Re-check chain tension.
BRAKE ADJUSTMENT
Brakes
Brake Lever Adjustment
The front left brake lever (1) should have 2.0 - 4.0mm (0.08 - 0.16) of free play.
To adjust brake lever free play:
- Loosen the jam nut (2) on the brake cable.
- Turn the adjuster nut (3) until the correct amount of free-play is achieved.
- Re-tighten jam nut (2).
Brake Adjustment
To adjust rear brakes, loosen the rear axle bolt (4). Locate the adjustment nut (5) on the rear brake drum assembly. Turn the adjusting nut (5) clockwise to increase braking, counter-clockwise to decrease braking.
THROTTLE ADJUSTMENT
Idle speed adjustment
The idle speed should be set at 1700 ± 150 RPMs. A service center can perform this adjustment, and a diagnostic tachometer is required.
To adjust the idle speed:
- Locate the idle adjustment screw (1) on the carburetor.
- Allow the engine to warm up for approximately 10 minutes.
- With the engine running, turn the idle adjustment screw in or out at small increments until the correct idle is achieved.
Throttle Cable adjustment
It is important that the throttle grip has a certain amount of free play. The hand grip throttle free play (2) should be .078 - .24 in (2-6 mm).
To adjust freeplay:
- Loosen jam nut (3).
- Turn adjusting nut (4) to the proper setting.
- Once the throttle grip has the proper freeplay, re-tighten the jam nut (3).
