When mounting AirShoxs to any bike, clearances must be considered due to the larger diameters of parts of the shock.  Ideally, check fully extended, recheck fully collapsed.  Positioning of air valves is critical to avoid damage. Long travel laid-down Shoxs usually require top valve forward, bottom to rear.  Wear of mounting hardware, top-out & bottom-out bumpers can exaggerate the contact points.   Click on the images to the left for recommendations to consider.  The pics are from a CR250R, but they apply to all bikes.  In addition to cutting of swingarm and top mount, the down tube in front of the top cap leading edge should be dimpled for clearance.  On show bikes with snug mount hardware, this may not be required as long as no one sits on the bike and bottoms out the suspension.  Finally, look for possible rub from number plates or side panels.

Due to how even just a tiny sliver of metal can puncture a bladder, Only bladders that I install are guaranteed.  Please see the photo of a rebuild from another shop I took apart, in my work, I always remove the air valves for cleaning and resealing.  Thoroughly clean shafts and lower cap, inspect for sharp edges and burrs, obstructions in shaft ports, lightly coat bladders with oil before installing.
