taylo63 Posted October 29, 2009 Report Share Posted October 29, 2009 I would like some advise please. My 07 Scorpa has an intermittent running problem. The bike starts and runs fine most of the time but occasionally the engine dies. It sounds like it is a fuel starvation problem ie the bike revs increase,then it will either stall or if I'm lucky continue running if I rev it a bit. I have had the carb off and cleaned it thorougly, so i'm at a bit of a loss what to check next..Any ideas anyone ? Thanks Quote Link to comment Share on other sites More sharing options...
godzilla Posted October 29, 2009 Report Share Posted October 29, 2009 Empty the tank and remove and clean the petloc, often these get blocked from crud in petrol cans ect. Quote Link to comment Share on other sites More sharing options...
paulmac Posted October 30, 2009 Report Share Posted October 30, 2009 (edited) If you still have the tank vent tube fitted - check it's not pinched, particularly where its zip tied to the frame tube, or not partially blocked, and check the ball is free in the tank cap - a damn good shaking usually fixes it.

thomastomsk Posted October 30, 2009 Report Share Posted October 30, 2009 i had the same problem a few weeks back,and did what has already been said,but also make sure your fuel mixture is 70ml to every 5ltr and the mixture screw on the carb is 2 and a harf turns out from fully in ,i did this and it runs great and has never cut out since..

joekarter Posted November 1, 2009 Report Share Posted November 1, 2009 If the other ideas don't do it, make sure all the carb vent tubes are clear and not pinched. Quote Link to comment Share on other sites More sharing options...
