How to Repair a 1988 Honda 80 Dirt Bike
- 1). Remove the motorcycle's carburetor and clean it with carburetor cleaner, getting rid of any and all grime and deposits within. If necessary, use an air compressor with a small tip to blow out any clogged lines within the carburetor.
- 2). Check the motorcycle's fuel tank for old fuel. Drain the fuel tank completely and refill the tank with fresh fuel. Old gasoline isn't good for most motors, especially older ones.
- 3). Remove the motorcycle's seat by unscrewing the two mounting bolts on both sides of the back of the seat with a 12 mm socket wrench. Pop off the top of the air box and remove the bike's air filter. Clean this thoroughly in hot, soapy water. Rinse it off, let it air-dry then apply air filter oil before reinstalling it in the motorcycle.
- 4). Check the tire pressure and integrity of both tires on the motorcycle. If either tire is flat, leaking air or overly worn, replace the tire and tube.
- 5). Change the motorcycle's oil. Warm the bike up, then remove the oil drain plug underneath the transmission and drain the oil. While the drain plug is still loose, fill the oil reservoir until oil begins to run out of the plug. This means the reservoir is full. Tighten the drain plug.
