    I dont know about the Kaw but on a Kohler twin the hydraulic lifters can pump up when there is a failure like that. Then when you replace the broken part the pumped up lifter pushes things past where they like to be and breaks things again. Ask me how I know this??:hammerhead: On the kohler you can assemble and let it sit before turning over hoping the lifter will colapse back or remove the lifter, dissasemble it and dump the oil.

    That eng. has solid tappets. You need to pull the head and take a CLOSE look! Could be a broke spring, seal, sumpin' in the cyl........

    I've had a couple of Kawi heads, the guide comes dislodged from the head and bends the pushrod/and or breaks the stud.
