Well, the "do it yourself" Honda manual states to "disconnect fan motor harness, remove rad lower bolt, rad upper bolt, remove rad forward, disconnect coil connectors, and then remove plugs". Not sure what is worse, this, or taking off the tank and box....BTW, it states that you MUST use a wire feeler gauge- and that the 0.04 inch one should not go between the gap. If the 0.04 can go through, change the plug. It seems the iridium plugs cannot be regapped.
