I have a 1991 Kawasaki 550sx and a 1989 kawasaki js440. I need engines for each one. Let me know what you have. Must be in GOOD running condition and have good compression. The 550 must be a reed engine. Let me know what you have. Short or long block is fine. [email protected] or PM me. Also may be interested in doin a 650 conversion so if you have a complete 650 with electronics please let me know.
