I have just got my XJ back on the road this Summer after finally fixing the first gear problem. Ran great most of the time - now it keeps fouling the #1 plug only after only a few miles of driving. Gets to the point it stops sparking. I have had the carbs apart and cleaned them @20 times - did have a gas overflow problem earlier in the Summe - I think that's fixed.
What are the signe for a bad valve seal? The bike doesn't smoke at all. The oil level stays up (though the oil light intermittently comes on when its hot). I kept checking when the oil light comes on and levels are good.
Any ideas on the plug fouling before I rip the head off and rplace the valve seals?
Thanks
