    ultra150 cylinder spacing?

    Need to know the distance between cylinders on the triple ultra150 / stxr motor. Easiest to measure between plugs or bolt. Reference the twin Kawasaki motor and zxi is 120mm between cylinders

    Need to know. Thank you

    I did once measure this but didn't write it down, but it is bigger than the 1100, i was measuring to convert a blown center cases into a 2cyl version, plugs should be good enough because they have locator tabs or even the water channel bolts. if you do measure the plug holes measure from the edge to edge and not try guess the center
