Another thing i would recommend for at least the first oil fill, use the correct weight, probably 10w40 for yours, not sure. but use the Kawasaki K-TECH oil, it has higher levels of Zinc (zddp) and phosphorus and other anti wear additives which have been almost erased from modern automotive oils because of the E.P.A, which is not good for small engines with flat tappets. If not buy a zddp additive.
