[Parts required separately] Tappet cap:Kawasaki stock part number (12032-1066) ・Tappet shims (*Measure the tappet clearance and use the required size of stock Kawasaki products.)
The retainer and cotter are machined (from high strength special steel) for precision.
[Effect of valve retainer & cotter set]. Since the retainer (approx. 50% lighter than STD) and cotter (approx. 75% lighter than STD) are lighter than "inner shim" which uses only genuine parts, the inertia weight of the valve train can be reduced and durability can be increased.
[Terms of Use] ・Valve, spring (*1) and spring seat are stock Kawasaki parts (square groove). (※1: The inner valve spring should be used with rounded corners on the top face end.)
Points of Attention
* If there may be an instruction manual included, it will be written in Japanese.
Purchased to match the resale of the cylinder head. I have been using the Yoshimura Parts for the STL-1 Cam and mjn carburetor and I feel that there is no other manufacturer of Aftermarket Engine parts than the Yoshimura Parts. I'm sure of it. I was very impressed with the accuracy of the machining process in my hands.View Detail
