Serious drop in MPG

I have lost 10 MPG over last 1000 mile, started around 6500 seems to get worse at each consecutive fill up. Ideas?

Someone is stealing your gas.

Seriously, pull a plug and have a look. Is it running OK?

Air Temperature!

This is assuming that prior to the last 1000 miles, you were riding in warmer weather.

Air temperature can do two things to fuel economy:

-Air is more dense when cooler and you experience more resistance at speed.

-Air effects spark timing. Because head temperatures will be lower, spark will be advanced (automatic) due to slower fuel combustion rate and fuel econ will suffer.

could be any of the above stated reasons... or... maybe you're riding her harder now that you're more comfortable on her?
I dunno, just a guess.

Be aware of wind directions. Just the other day I rode all day in a strong head wind and got about 10 mpg less on about 4 consecutive tank fill ups.

My mileage really dropped off when it got cold...it will be interesting to see if it goes back up now that it is starting to get warm.

Steve

I bought a motorcycle because my wife said that I couldn't! Now I have two and she still says I can't have another one!

Sounds like a challenge to me!

Now I have four!

Yep, to all...

Likely all of the above mentioned conditions contribute, definitely colder now as I bought the bike in May, is windy, is time for plugs & filter, we do have winter fuel formulas here, and yes I am much more comfortable riding that I was last summer. Thanks, I feel a bid relived from your comments.

Anyone using KN Air Filters in the Versys?

I had the same prob. I put most of the blame to winter gas and winter city driving, (I haven't done any trips) I've had my gas mileage dip into the high 30's (UGH) I actually changed my plugs and it shot up to 45mpg and that is with HIGH revs... so it is also warmer now so all together I hope when I mellow out on a long trip it will go back into the mid 50s... so yeah... thats my experience

08 Versys 32+k and counting
