At 3000 miles altitude, you should switch as per Honda Service Manual to the smaller jet configuration as you obviously are running very rich. You should have gobs of power at 3.5k rpms.

I bought the smaller jets at the Honda dealership for $9 a piece and had them install them for 1 hour labor fees. I found the throttle response to be "snappy". I went from 41 mpg to 45 mpg, but then again, I'm at an altitude of 5280 feet and often run twisties at around 8000 feet. At 3000 feet, rejetting would probably be a good idea.

I've noticed a lot of people are getting *** for gas milage. There's a lot of factors to consider for that though.

I generally shift around 3k to 5k rpms. Many with poor gas milage are often in the 9k range.

I'm also using 91 octane. I found I get 2mpg better gas milage than 87 octane, despite the manual. This really doesn't make sense but oh-well. Maybe the gas station I'm at has crappy 87?

It's important, also, to make sure your chain is on right with the proper amount of slack and greased properly, as it'll rob you of power otherwise.

Having the carbs synched-up dead-on is vital. I find this 90-degree V-Twin is very tach non-bouncy compared to 60 and 45 degree ones. If the idle is bouncy, your carbs might be out-of-sync. Have the dealership or someone with a vacuum guage do it for you instead of the traditional "all the way in and back out 3/4 turn bullshit" because that never works EVER.

How's your tire pressure? Are you at spec on those? Again, mpg will suffer.

Consider having your carbs cleaned professionally at the dealership. This is about 1/2 hour labor and well worth it.

A half bottle of Gumout Carb Cleaner never hurts too.

Have you checked your air filter? Might be clogged up!!!

Good luck and try some of those things and let us know if it works out for you. With the weather being so cold nation-wide, getting into a Honda motorcycle dealership for instant service will be a breeze as they're probably doing nothing right now!
