Isolated issue ?? What planet are you from ? Try and find a cylinder or a motor for the new style phazer, they are not avaliable. The motors are way different than the old style and do have problems with the piston skirts breaking. Do you have one, have you ever touched one ? I loved the light weight and handling and the motor was plenty strong until it sneezed. I had no issues with it until it died. The venture had the same power plant and Yamaha discontinued them in 01 for unknown reasons. I really believed I had a true phazer motor until I went looking for parts. Found guys in the mountain states that had the same issues. The ring pin was still intact and the lower end is beautiful, with the exception of the bent rod. I am still on the lookout for a cylinder, Millinium does not even cary these or have a part number that crosses. Isolated my butt !
