[QUOTE="GhostofSilverider, post: 1414427, member: 121135"] I changed the petcock that was leaking, but it still fouls plugs. The jetting is stock on this steel tank euro model (main #152, not sure what the pilot is), despite a derestricted pipe which would normally call for a bigger mainjet. But I left it like I got it from previous owner (he did the pipe mod, added aftermarket silencer but left lid on airbox). That's because the bike appears already way too rich as it is (lots of spooge , outside and on the piston). Previous owner was running a Champion N 2G, plug now replaced at Champion by RN2C, and that plug lasted a bit longer despite being colder than the B8ES I run (as recommended by manual). So now I am thinking switching to Champion RN3C (one step hotter than RN2C), hoping to extend plug lifetime which is 2 -3 rides currently. Spooge has also leaked from the drain plug (left side), and from the spark plug hole. Oil level remains the same. This bike is know to foul plugs, and mine has less than 2k miles on it so I would be surprised if the problem was caused by a broken part. I am looking for a fix, it 'is starting to become expensive to replace those plugs. [/QUOTE]
