ATTENTION vintage Kawasaki JETSKI collectors or FAST 300cc. Made in Japan in the mid-1980’s… NEVER to be made again!! This complete Kawasaki cylinder and head combo can be used on all years of 300cc jetskis from 1986-90 AS-IS! Complete top-end will work without modifications on all 1986-88 JS300-B hulls and or the 88-90 300SX type engines! This trick RACING combo came from a ski that was used in FRESH WATER conditions ONLY… The TRICK racing cylinder combo using this head had 190PSI cranking pressure at 2500FT! You can see in photos the head has had massive milling, it is lots thinner then OEM stock type heads! Please look close at pics for any, and ALL damage…. One 300cc cylinder and head combo does have NORMAL WEAR AND TEAR from daily jetski USAGE [SEE PICS]. Two bore size is. 020thou over size or. Bore could use a hone job to use as-is? The engine cases had a brass barb hose-pulse fitting tapped into the side of reed cage area on the side of engines cases. Four one cylinder stud bolts top does have a wear spot in threads[see pics], but threads all work okay. This modified topend came off a great running ski I parted out several years ago, I pulled it and in a box it went! The last nice original 300cc. THIS IS the LAST Kawasaki 300 ported topend I have from a famous jetski company from the 1980’s! I owned several cylinders with different stages of modifications; from radical to mild. This cylinder was not as radical as others. I know the former Jetski company owner very well, but he asked me to not use his company name in listing. They built these experimental cylinders for their team riders to race against other 300-500cc racers in the late 1980’s. They would build a cylinder with different porting spec’s, go run it, then build another. It was OEM black painted when I got it, I had it painted Kawi green in the mid-1990’s. Racing top-end is worth vintage jet ski value for sure… Trick racing Kawasaki 300 parts are impossible to find now. Complete topend combo can be used as-is on your vintage Kawasaki jetski 300cc. Racer or playtime jetski. I’m getting out of the sport of collecting vintage Kawasaki JETSKI’s. My LOSS is YOUR GAIN! IF you’d like a mint, unused/ new museum perfect Kawasaki 300cc.
