Using a GameBoy to diagnose a problem with an Aprilia SR50. Sometimes this scooter would have a sudden loss of power (SLOP) at wide open throttle (WOT). Otherwise known as SLOP at WOT. Unfortunately there was no power loss is evident in this video. The problem was eventually traced back to the fuel pump loosing pressure at WOT. Replaced the fuel pump and now the scooter runs great!
