On 3/9/06 I lost the front cylinder, and attributed it to a clogged cooling line (first pic). Well, it happened again today, and both pissers were flowing normally both before & after.:banghead: :banghead: :banghead: :banghead: (all other pics). Rear cylinder is fine. In both cases part of the upper ring was missing when I pulled it apart
I'm at a loss as to why this happened, or exactly what did happen. Did I lose a ring in the exhaust port, leading to the melted piston? Front exhaust port width is 56mm; rear exhaust port width 55.4 mm. The bore & chanfer job was done by Paul Lehr, so I'm sure it was fine.
Both carbs were jetted the same, and the ski was hitting fine off the bottom before this happened (in the surf BTW). Piston wash shows jetting was OK.
Any ideas what happened? Can this cylinder be made reliable?
