2018 Kawasaki Ninja EX400 This is a Completely stock 400cc off of the show room floor compared the same motorcycle with a Spears Racing Spec Kawasaki 400cc Supersport Build and this is dyno’d on 89 Octane pump fuel, This was built with all Kawasaki Products, and a few other products listed below.
The cylinder head was done to the Spears Racing Spec or the competitive valve job (Referred to a SUPERSPORT Style) the valve faces and stems are machined, and the intake valves are given a special double cut. The exhaust seats are given a three angle cut. The intake seats receive a blended four angle cut or full radius cut depending on the application. Finally all valves are hand lapped and checked for correct sealing. All of the seat work is done on our state-of-the-art valve machine. Once the cylinder head has been machined and thoroughly cleaned, it is time for reassembly. Careful assembly of the cylinder head involves checking valve spring height and pressures as well as setting the valve lash for proper clearance. Our Services
