I think these bikes get better mileage running gallons versus litres through them. Litres being smaller than a gallon, they run through the carbuerator plumbing and engine faster??
But seriously, there's so many variables affecting individual fuel economy, I'm never sure what to make of them. I do know that when completely stock I got ~48mpg and after epcos, rejetting w/160 mains and installing the K&N's I went to a steady ~43 mpg. And after adjusting the carbs to rid a persistent backfire, I apparently dropped another mpg or two. No hard records, it's all in my head. Trust me!!
If I could ever find some way to slow down and not run the gears at a high rpm I could probably find some of those missing mpg's. But where's the sport in that
.
The mileage you describe sounds pretty bad however. Gotta be something going on as mentioned above.
