01 400ex, how to get onto the fuel screw, its impossible to get to... also say i'm on the left side of the quad, do i turn it left or right for lean

 

[Here 2 help]

It takes a special right angle screwdriver (Motion Pro makes one) or the screw needs to be replaced with one that you can turn by hand (several brands available)

Turn clockwise to lean (turn in)(right hand threads) from either side of the vehicle
