Tutorial Reparación económica motor Scooter (Gilera Runner 50 SP). Remix de dos motores (2ª Parte).

Part two of a Gilera Runner 50 SP engine repair. From two engines—one with a seized crankshaft bearing and another from a salvage yard—we've combined the best parts from both to create a perfectly functioning engine. It was an expensive repair that we tackled in an "economical" way by recycling engines and parts.
