I have access to 4 maybe a few more new K 90 motors. These motors have had the sleeve mod to allow cooling the piston on the exhaust side of the motor to prevent sticking. These motors have very little taper in the sleeve when they were made and I came up with a way to cool that side of the motor with fuel many years ago. They also have the full needle load in the bottom end of the rod. But other than these two things the motors are box stock new. Going to ask $500.00 each for these rare motors. And with good break in they will give you many years of good service.
