Anyone know how to set the float level height for a 2004.5 Sportsman 500 H.O.? It has a Mikuni 40mm CV. Problem was it was leaking gas out the float bowl overflow everytime you let off the throttle. I have it apart, everything is perfectly clean and no wear on the needle valve.
Need help quick, want to ride!!!!!

 

THATS USUALLY WHAT CAUSES IT,IF YOU USE CARB CLEANER ON NEEDLE INSTANT JUNK.IF IT HAPPENED BY IT SELF THATS USUALLY IT.

 

THE ADJUSTMENT IS 14.7MM LAYING THE VERNIER CALIPER EVEN ALONG THE BOTTOM OF THE BOWL MOUNT,LAY CARB ON THE AIR BOX SIDE TO TAKE THE WEIGHT OFF THE NEEDLE IN THE BOOK IT LOOKS TO BE PERFECLY FLAT+ EVEN ON BOTH ARMS IF YOU HAVE NO MEASURING DEVICE.A VACUUM TESTER ON THE FUEL INLET WILL TEST THE FLOAT NEEDLE VALVE.

 

You guys are awesome! Thanks for the quick reply! I'll check that and get 'er back together now.
