I had a bit of a non-productive weekend, Mrs Blatter had a migraine for most of it & I was suffering with something similar, so I didn’t spend a lot of time in the garage. I was also unable to pop over to Neil's “man cave” & turn down a fitting ready for the banjo connection (more of this later), so that’ll have to wait for another day.
I mentioned a fuel fitting, this is the Suzuki input to the fuel rail. As luck would have it the bent pipe on it is 180 deg from where I need it, & when I took it off I found that in contrast to the cunningly shaped lightweight aluminium you'd expect on a performance bike, this fitting was just a slab of steel. So I hatched a plan to turn down the fitting, open the hole up to 8 1/2mm, tap it M10 & fit a banjo fitting in it's place, you can see the before (current) & after (soon to be) pictures below & hopeful they make some sense. As luck wouldn't have it they are shown opposite ways round, so the photo is the downstream end, the drawing is the upstream.
