There isn't much to it. Having the right tools is the biggest problem. You need a real long 3 or 4 mm ball end Allen wrench to release the 4 Throttle Body (TB) tops at the air box.
- Lift tank and secure
- Remove battery (10mm socket/10mm wrench
- Remove top of air box (large Phillips
- Remove hoses (pliers to squeeze clamps, 4 total IIRC
- Loosen throttle body clamps (3 or 4mm Allen ball pivot about 10 inches long
- Pull up on air box and remove....
That's it. Reverse to install. When seating air box, make certain the soft rubber doesn't fold inward over the TB
Here are several pictures in an album if that helps...
