use of fuel

[DevonCbx]

When I go for about a 2 hour ride at about 120KMH I seem to suck up the fuel like it is going out of style. I know that the CBX is not a miser on gas but I cannot believe how fast the fuel is used up. Is this normal and what kind of gas milage should the bike be getting

[Rick Pope]

Unfortunately, around 35 mpg is common, perhaps even lower. Late models, and some early models, will get 40 mpg, butnot under hard running. My own '79 routinely gets about 36 mpg riding curvy roads, but not flogging it.

Even with everything right, you can drop into the mid-twenties mpg on hard running. '79s-'80s, as Rick said, usually do mid-thirties at best.

As I always say, this is a hot running motorcycle that is liquid cooled. The liquid just happens to be gasoline. :)

Duane, when i am wailing on the '79 the switch to reserve happens around the 135 km mark.
Works for me!

I average 25 mpg - I'm pretty sure I should have rejetted when I stuck on the Mac headers....

My 82 gets low to mid 30s, but my 79 gets around 28-30 most days. In Yellowstone one day cruising every paved road I could find on the 82, I got it up to the mid 40s, but I was flower sniffin all the way. From Cody to Sheridan WY I only got, well, I stayed right around 6,500 to 7,500 revs all the way, sometimes higher. Uhh, the mileage suffered a bit... but it sure was a fun ride!

My 72 Kaw h2 gets under 20 mpg. So mid 30's aint that bad.
