The Honda temperature sender in the cylinder head unfortunately works in reverse to the one needed by the temperature gauge i bought. So I got a 25mm coolant adapter, for some reason the seller specified the internal diameter so i had to machine it down a bit and while i was at it i decided to lighten it a bit too.

I might still alter the hose arrangement as the filler will foul the fairing and i'd rather not have to cut out hole for it.
