I'm getting 35mpg... Thoughts?

Howdy,

After a few fill-ups on my new bike I realized I am getting 35 mpg with mostly city riding. I have an Athena kit, FMF programmer (properly programmed) and an FMF pipe as the upgrades that might affect fuel. Does this seem right to everyone or very poor mileage? I was expecting about 50 mpg or so.... Thoughts on simple and cheap ways to improve?

Thanks!

Very poor mileage... unless you have it WFO all the time.

Am guessing it is an issue with the fuel programming.

Is the exhaust pipe black inside?
Smell gas or spent fumes when running?
Do you have both the Athena fuel programming kit and FMF?
Has the FMF been upgraded for bigger displacement?
What are the settings on your FMF?

I get 45-50mpg when I ride gnarly single track with lots of hills and power needed with a larger rear sprocket and knobby tires.

I get closer to 60 if I'm just riding curvy roads at 30-35mph or around town.

What do you mean by "properly programmed"?

Definitely something wrong. Also means you're missing out on some power.

A Chassis Dyno is the best way I know.....do people put D/Sports on dyno's like people do with street bikes?

No, doesn't seem right. My bike, with the Athena kit, pipe and PC5 with Autune returns about 60 mpg with fairly spirited riding. I'd say you're running too rich.
