Default Flt 1988 gas consumption

I have flhtc 1988 and I have a fuel consumption of 1 liter per 10 km. Doesn't that seem relatively high? What is the average on this model ,and if this high what is the main reason?

I'm thinking around 23 mpg, which is really bad. Here in the USA, we go by Gallons and miles. Have you looked at the spark plugs to see if they are black and sooty? Is the air cleaner element clean?

What model carb is on the bike?

The original carb would be a Kehin butterfly type carb.
