Number 1 plug may have more chance of fouling than the others if the air filter was oiled too much from the factory due to the fact that the oil runs towards cylinder 1 when the bike is on the side stand, otherwise probably plug or coil related, if it does it again swap the coil to another cylinder and see if the fault goes with it.
Thanks Mike that makes sense and will do. I am just confused with the general feed relay malfunction and whether this is related to the foul plug.. Electric-current wise that is.
What do you think of the plug's resistance issue i.e. instead of 4.5-5.5ΚΩ only 3.6ΚΩ? Or am I paying this more attention than it deserves?
