The ADA Racing Billet Heads for the Kawasaki 750 Jet Ski’s are made from 6061-T6 aluminum and CNC machined for consistency and performance. This head uses the stock head bolts and is clear anodized for protection against corrosion and feature dual water outlets for additional cooling. Head shell includes o-rings that fit into the grooves in the head shell and brass fittings. Head shells are available in standard or girdled version for those running higher compression and looking for extra insurance. The girdled version requires the girdled hardware kit sold separately. Multiple dome configurations are available to tailor to your specific engine needs. Two domes are included with this kit, additional and replacement domes are available separately.
NOTE: The 1992-1994 Kawasaki 750SX model will have about 15lbs higher compression than the readings shown in the dome drop down. You will then also need to adjust the octane requirements accordingly. All compression readings are on stock non-ported cylinders at sea level elevation. Cylinder porting will lower compression as well as increase in elevation. Compression will drop approximately 7lbs for every 1000ft increase in elevation. Ported cylinders will affect compression differently depending on how much the opening duration of the exhaust port was increased. On ported cylinders there is no way for us to know what the compression will be without a beginning reference point.
ADA Throttle/Choke Cable Bracket is sold separately and required when using stock carburetors with ADA Billet Girdle Head. This bracket has the throttle cable mount moved up, so it does not interfere with the girdle bracket.
