mafferz Posted May 13, 2007 Report Share Posted May 13, 2007 Hi, does anyone know if the mix screw on the carb screws in or out to lean off the fuel on a Fantic 205? also what fuel/oil ratio should it run on? Thanks, any info appreciated Quote Link to comment Share on other sites More sharing options...
motojojo Posted May 15, 2007 Report Share Posted May 15, 2007 80 to 1 on us gallon. In order to adjust your mixture, warm up the bike, turn up the idle, screw in the air mixture screw and rev the motor it will not rev down, then screw the air screw out at half turns until it revs down almost as quick as it revs up.

grib Posted May 24, 2007 Report Share Posted May 24, 2007 Use good synthetic oil at 50:1. The mixture screw on a Dellorto is a fuel screw not an air screw. Quote Link to comment Share on other sites More sharing options...
