This listing is for a complete MTC Engineering. What is more important to the rider of the motorcycle than compression ratio is the cranking compression with whatever camshafts are installed. When a camshaft with longer duration is installed the cranking compression of the motor will be reduced regardless of the type of piston installed. Com will rate our KZ pistons according to the standard cranking compression expected with a particular set of camshafts installed.
The MTC-K1075 piston kit is intended to be used with PSP-3X camshafts and the advertized cranking compression will be based on that application. This piston kit has 10.5:1 cranking compression when used with PSP-3X camshafts.
These pistons are manufactured in Cocoa Florida using the highest quality aluminum alloy. Each piston is subjected to a battery of quality control checks to assure uniformity and high quality. Some of the world's fastest motorcycles are equipped with MTC Engineering pistons. This MTC Engineering piston kit contains the following: (4) 72mm aluminum forged pistons, 10.5:1 cranking compression with PSP-3X camshafts (4) Hard chromed wrist pins. (4) Sets of 72mm rings.
(with three piece oil ring) (8) Teflon buttons sized for a 72mm bore. (buttons take the place of circlips) (1) Cometic two piece fiber head gasket with center o'ring. The picture shows a copper gasket, but fiber works better for sealing.
If you have ever seen what a dislodged circlip can do to a piston and cylinder, you would never use them again. You get all parts shown in the picture. This piston kit will fit Kawasaki Z1, KZ900 and KZ1000 models. For use on a Z1 or KZ900 either the sleeves must be changed in the 903cc cylinder, or a KZ1000 cylinder must be used. This covers all models from 1973 through 1980.
The pistons have 17mm wrist pins. They have valve reliefs sized for 39mm intake valves and 33mm exhaust valves.Com offers a complete machine shop service.
