What's yours doing?
If it's a bit excessive, probably down to your fuel pressure regulator. As I said, pressure is a bit high, which will cause it to run rich, and use more fuel.

My twin spark has always done between 82 and 87mpg, I only acellerate hard when needed and run in top gear as much as possible, but it does get quite a bit of 80mph running and always has panniers on. What it does not get is short runs, not less than 100miles and mostly 2/300 at a time. 265miles on a tank is the record so far and it still had 1 1/2litres left. Sue
40 mile commute, mainly motorway, but that's got at least 5 miles of slow moving traffic and the rest is trying to cruise at an indicated 75 mph = 5000 rpm, and I'm getting 14.5 miles per litre which is about 180 miles to the light or about 66 mpg
