What kind of porting does a Kawasaki 750 jet ski use?
The porting mods used in all of our 750 kits is the result of many months of performance and wear evaluation testing. We confidently claim that Group K cylinder porting will yield a wider power band and longer piston life than any other porting modification available anywhere.
What kind of engine does a Kawasaki Jet Ski have?
The 750 introduced underwater exhaust for quieter operation to the stand-up kawasaki. The 750 SXi (JS750-B) is introduced, and became the first stand-up Jet Ski with dual carburetors. Kawasaki introduces the SX-R 800 (JS800A), which increased displacement to 781cc, in the form of an in-line twin 2-stroke engine generating 80hp.
What should the piston clearance be on a Kawasaki 750?
PISTON CLEARANCE – It’s common for a new 750 cylinder to have as much as .006″ of piston to cylinder wall clearance. (set-up clearance is .0035″-.004″ ; wear limit is .008″). Excessive piston clearances (factory set at .005″-.007″) are the primary cause of the piston skirt cracking that many 750 engines have experienced.
What causes air leak on Kawasaki 750 jet ski?
Air leaks, not engine modifications, are by far the number one cause of 750 piston seizures. Group K offers a simple-to-use pressure test kit that allows you to quickly test for any air leaks that your engine may have. (kit includes block offs to test all current Kawasaki, Yamaha & Sea Doo models)
When did the Kawasaki 750 jet ski come out?
Kawasaki introduced the all new, JS 750 stand-up Jet Ski in 1992. With a 743cc, two-stroke, twin cylinder engine, this new, completely re-designed model was faster and more maneuverable than the 550 and is still one of the most popular stand-up watercraft.
The 750 introduced underwater exhaust for quieter operation to the stand-up kawasaki. The 750 SXi (JS750-B) is introduced, and became the first stand-up Jet Ski with dual carburetors.

What kind of engine does the Kawasaki SXI pro 750 have?
It was fitted with 140mm pump, a diameter that would be retained by all future 750 stand up models. The ’95 SXi featured the new “big pin” engine format (so called because of the much larger piston pins). These big pin engines also featured an all new cylinder port layout that employed much more radical port timings.
What’s the maximum displacement of a Kawasaki sxr800?
849cc Big Bore Mods for the Kawasaki SXR800 & SXi 750 For the 2008 racing season the IJSBA is allowing 2cycle stand-up race crafts to have a maximum displacement of 850cc. For Kawasaki SXR owners, this means that pistons up to 85.4mm (3.4mm over stock SXR pistons) will be permitted.
