OK, I did a search but could not find any reference to how you change the spark plugs, especially the front one.
Looking at and reading the workshop manual, it says to undo bolts A and B (as shown in the photo), which I did and pull the radiotor forward, again which I did. However, what they fail to mention is you can pull the radiator only about an inch or so and someone has to hold it in the 'pulled' position for you to be able to get to the HD lead.
Anyway, got to the HD lead and pulled it off. It came off very easily so I assume it had gone loose, hence the problem with the bike.
Now for the life of me I cannot get to the spark plug, cannot reach it with my fingers, cannot get it loose with the plug thingy and cannot insert the HD lead back onto it properly as the washer cap thingy on the HD lead prevents it from being inserted completely to clasp onto the spark plug.
Is there another way like removing the fairing, the forks, the tank, the front wheel and possibly just taking an electric saw to its front just to get access to the effing plug? How do you lot (who say you have changed plugs) do/did it?
