...wow this is actually pretty cool...Cuz i'm having the same problemSmokes SOMETIMES when i start it up in the morning, but not at all when im driving-or once it's warmed up.Anyway, my uncle said it was the valve seals(guessing by the symptoms),so i had the head FULLY re-builtCome to find out, my head was cracked, so it ended up costin $350, but at least i knew the problem was fixed.NOPE!Not at all, in fact it runs almost exactly the same, with the exception it doesn't ping up hills, and has a LITTLE, VERY LITTLE, more bottom end.So could it be the rings?Even though it doesn't smoke when i'm driving or once it's warmed up??It does seem like it should have more power though...
