    Quota 1000 Fuel Pump

    So I finally replaced the air temperature sensor but the symptoms didn't change. I checked the valves and the intake had no clearance whatsoever. Tuned them but unfortunately the bike is still very difficult to restart when hot and stalls at full throttle. On a cold start the quota revs up...
