Another project has arrived to keep the 750F2 company (while it waits for me to get round to it).
Just picked up a 400/4 F2. More or less original besides added corrosion! Will post some piccies when I get time. As opposed to cafe project on the 750, this will be kept as Honda intended.
Hasn't run since 2004 I am told. It won't now either - spark seems ok but carbs full of fuel residue - see my other post.
