Owners of "race only" Kawasakis using the poplular "j model" or GPZ1100 cylinder head can now remove the smog hose caps without leaving those ugly holes in the valve cover. These APE billet caps are CNC machined for a perfect fit and stunning good looks. Fits all 1000s and 1100s with smog hoses in the cam cover. Sold in pairs, allen bolts included.
