Fuel Economy
 

Will adding an aftermarket air filter and exhaust help fuel mileage as well as performance?

The best thing to help mpg is your right wrist. Stock or heavily modified, I never got good mileage. As always: YMMV! (sorry, I couldn't resist)

Performance probably yes, economy no as with aftermarket exhaust you usually need to rejet it.

I've been beating the crap out of the ole girl lately and still getting 36-37mpg. What the hell are you guys doing to get such poor mileage?

Bad Gas?
 

Lousy gas? I'm only one up on the mains, stock needles shimmed .042", OEm filter, 2Bros LM AL cans, TPS recal'd, 55k miles, M1 15W-50, a far bit of added weight from add-ons, 230# w/gear and at best I get 35 and avg 33. What gives? Its a SH...

yeah, ditto. the worse i get is about 33. I am so happy with this bike after greg helped me fix the jets. You rock! :)

dude, 33-35 is great for a carburated v twin. Where is the problem?

I got 43 mpg around lake michigan doing 90mph most of the time

I can get at least 35 mpg and close to 40 mpg most of the time running 93 octane even with a seriously twisted right wrist. If you're looking for 60 mpg get a moped bro:P

Doh
 

Read my post again, that is what I was saying. BTW, my 16/43 sprockets don't help mileage either.
