What height should the float levels be set to on my 350 ypvs

SOURCE: float hieght for 1984 IT 490

not sure of the exact height, but if you hold the carb level with fuel hose attached and pushing float up with finger, turn on petcok and slowly lower the float until it is just above horizontal. at this point, gas should start to flow out of the needle & seat.

if float turns off gas too soon, then engine will starve.

if float doesn't turn off gas, then it will flow out of the carb overflow tube.

YOU CAN ADJUST FLOATS WITHOUT SPECIAL TOOLS. ALL YOU NEED IS A FOOT LONG PIECE OF CLEAR TUBING, SIZED TO FIT THE BOWL DRAIN. SET FLOATS AS CLOSE TO WHAT THEY WERE WHEN YOU REPLACED IT. INSTALL THE BOWL AND PUT THE TUBE ON THE DRAIN. OPEN THE BOWL DRAIN SCREW WHILE HOLDING THE TUBE UP BESIDE THE CARB. WHEN YOU GET THE TUBE BESIDE THE CARB ASSY., THE GAS IN THE TUBE SHOWS YOU THE EXACT LEVEL OF FUEL IN THE BOWL. FROM THIS YOU CAN MAKE ANY ADJUSTMENTS NECESSARY FOR CORRECT LEVEL. THE LEVEL SHOULD BE RIGHT BELOW THE PLANE WHERE THE BOWL MEETS THE CARB BASE.

YOU CHECK FLOAT LEVEL LOOKING AT THE SIGHT GLASS ON THE RIGHT OF THE CARBURETOR.FUEL LEVEL SHOULD ALIGN WITH THE DOT ON THE SIGHT GLASS.IF THE LEVEL IS ABOVE OR UNDER THE DOT THE CARBURETOR HAS TO BE DISASSEMBLED.TO SET FLOATS REMOVE AND INVERT THE AIR HORN UNTIL THE FLOAT ARM JUST TOUCHES THE NEEDLEVALVE OR THERE IS ABOUT 0.1 mm OR 0.004 INCH CLEARANCE BETWEEN THEM.MEASURE THE DISTANCE BETWEEN THE BOTTOM OF THE AIR HORN GASKET INSTALLED.AND THE CENTER OF THE BOTTOM OF THE FLOAT.THE DISTANCE SHOULD MEASURE 36.4 mm 1.39 - 1.47 INCH. ADJUST BY TURNING THE NEEDLE VALVE SEAT.BE CAREFUL NOT TO ALLOW THE VALVE SEAT TO PROTRUDE FROM THE SEAT ATTACHING BOSS.WHICH WOULD ALLOW THE VALVE TO FALL.IF THIS IS THE CASE BEND THE FLOAT ARM SLIGHTLY UNTIL PROPER CLEARANCE CAN BE OBTAINED.WHEN CARBURETOR IS INSTALLED CHECK FLOAT LEVEL BY LOOKING INTO THE CARBURETOR FLOAT SIGHT GLASS I MENTION IN INFORMATION ABOVE.IF YOU HAVE A 1487cc AND 1600cc CVCC MODELS WITH THE KEIHIN 3 BARREL CARBURETOR.THIS WOULD DEALERSHIP JOB.THIS TYPE IS HARD TO ADJUST.
