hi although it is a bit tight for space the least parts removed the better, with the middle fiarings removed you should see the top of the cylinder heads, remove each cap 1 at a time and replace the plugs using the spannner in the bikes tool kit, if this way proves to difficult you will have to prop up the fuel tank, remove airbox and get at the plugs this way,paul
