Well I am finally getting around to repairing my Tri-Z from the NW trike rampage, (call me a slacker) pulled the head off last night and the piston is junk, I belive a piece of the ring broke off and made its way into the combustion chamber, and caused damage, new piston, hone the clyinder, where do i go for a base and head gasket for it. And while i have it aprt im gonna put new reeds in it, who makes em lol. Thanks Mike
