      GV250 Aquila

      Hello,

      My gv250 idles strong. In neutral it can rev to red line. Up on stands it can cycle through each gear to high RPM. However with a rider it dies after 100ft or so. It dies in both 1st and 2nd gear. After it dies it will turn over but wont start up for 10-15 minutes.

      Thanks for any help 👍🏼

      It’s got to be low fuel supply to the injectors, it be the filter that is fixed onto the pump or it could be a tired pump

      I will pull the filter bag thing off to see if that fixes it. If not I have an 07 gv250 with an almost identical pump and I’ll swap them out.

      Do you know any way to test the fuel pressure without a gauge? I’m in the middle of no where Cambodia and there’s not a mechanic shop that can service “big” motorcycles anywhere

      For fuel-pressure, you can use a tire-pressure-gauge…

      +a hose connected directly to fuel-pump-outlet…
