the mono block xlt motor usually needs the pto cylinder richer. this is the hottest cylinder in this motor. furthest from the water pump. it's the ctr, cylinder on ultra's, 800 xcr. but like was said not every motor is the same. piston wash, plug reading, and ex. gas temp should be checked and jetting adjusted on the findings.
