Take the tank off to get at the rear ones - disconnect the fuel gauge sender, the petrol pipe and the bracket holding the cables to the fuel tap drum in order to remove them; the tank can then be lifted off.
To get at the front plugs take the side fairing panels off and undo the bolt holding the radiator stay to the head: swing the radiator forward. You will then be able to get the spark plug socket provided in the tool kit into place over the left plug - just!
The right plug is much more difficult as the plug spanner interferes with the fan housing: you simply have to force the radiator forward as far as you dare and try and force the end of the spanner past it - my radiator bends while I am doing this - it's a real pig and I always feel that it's touch and go as to whether I brake the radiator or not. I wonder if anyone at Honda ever tried this on the prototypes! (mine is a 1990 FL).

Go to your local Honda shop and get the correct NGK plugs. They will come pre-gapped. This applies to all NGK plugs. You can verify this at their website. brad The manual says the correct gap is 0.8-0.9 mm (0.031-0.035 in) if you happen to get plugs that are not gapped. Hope this helps.
