"About 1000 miles per gallon is what's claimed, although I will be using a bit more as I keep the oil injected at a slightly higher rate as oil is cheap; rebuilds aren't".
"Wow that seems very excessive Martyn"
Compared to the less than 200 miles to the pint of oil that my Vincent Series C twin used to do, it doesn't seem too bad. Despite it also being dry sump, it used to blow most of the oil out of the timed engine breather that used to open when the pistons were on the way down and close when they were on the way up.
