How to Fix Pocket Bikes

By Robin Reichert

Pocket bikes are like small motorcycles that are capable of speeds up to 49 miles per hour. Pocket bikes are far less expensive to repair than traditional motorcycles because they are smaller, more portable, and less complex. Tire air pressure, seat wear and tear, float problems, problems with the bike stalling and carburetor cleaning are common repairs required in pocket bikes.

The Process

Increase the air pressure in the tires after a tire change or to add air to existing tires. Using an air pump or air filling machine, attach the hose tip of the air pump to the valve stem on the tire. Test the tire pressure with a tire gauge to ensure that it is at 30 PSI for the front tire and at 32 PSI for the back tire.

Replace a worn out seat by removing the two bolts that attach the seat cushion to the bike. Place the new seat cushion on the bike and resecure the two bolts.

Repair a stuck float by bouncing the back end of the pocket bike up and down to clear any dirt and debris and to loosen the stuck float. Drain the gas tank and replace the black gas tube by removing the two side screws. Remove the float and clean it; examine the gasket for blockages. Replace the float and retighten the two screws.

Change the spark plug to resolve problems with stalling. Examine the plug after removal. If the plug is black your gas mixture is too rich, if it is white the gas mixture is overly lean, and if the plug is caramel color the gas mixture is good. Replace the plug with a pre-gapped plug. Replace the plug wire with a new one, if necessary.

Clean the carburetor if the bike continues to stall. Loosen the hose clamp on the air filter and remove the velocity stack and carburetor engine. Remove the gasket and unscrew the throttle cap. Loosen the nut on the choke and remove the choke and float. Spray the components with carburetor cleaner. Clean the jet retainer and remove the jet assembly with pliers; clean the manifold ports. Reassemble the carburetor and reinstall it.
