ever since I bought my 2011 V the fuel mileage hasn't been good at all...and it seems to be getting worse with time.....first 600 miles I was getting 43-45 at about 1000 miles it dropped to 40 and now its down to 35.5 any ideas....The only thing I have done mechanical to the bike was remove the charcoal canister.. I tend to run the bike in the 5500 to 7000 rpm range......

ideas ???

It could be:
  • You're getting faster. :devil: :D
  • a change in gas formulation for the winter (ethanol drops your mpg quickly)
  • higher average wind speeds than when you first got it (not sure where you live)
  • you're not filling it up as much as you did previously
  • the gas pump(s) you visit are off on their metering
  • you have a leak somewhere in the fuel system
  • something else altogether (I know, not helpful but I like to cover my bases)

I removed the canister on my '09 also, and I get about 50+ mpgUS, which is NOT quite as good as I get on my '08 - high 50s to 60 mpgUS.

I'm going by memory as I haven't ridden the '09 since early October (it's in Canada, and I'm NOT), but the '08 figures are current. :eek:penarms:

question isn't the tank vent suppose to just vent fuel in an overfill condition?? when I parked(put it on the side stand) it just now after running about 10 miles it spit out fuel on the ground....tank is less than half full.....what would cause that....

Sorry, I hope this is not a dumb question. What "cannister" did you remove? Where? How? What effect does it have on the bike?

Why do you run the RPM so high? Do you not shift into 6th gear as soon as speed allows? Isn't 7000 RPM like 90 mph with stock gearing? I have a one tooth lower front sprocket so my RPM on the slab is about 6000 which 70 mph and I enriched the mixture a little with the TPS and I am still getting 55 mpg and my canister is still hooked up. Why do you people remove emissions related items that have no impact on performance? Also there really is no reason to roll around in lower gears on this bike. If you are going over 45 to 50 mph you should probably be in 6th gear.

no not always u can be in 4th or 5th gear and turning 7000 rpm and not be going 90..why? because the engine has more power and torque above 6000 rpm and is more fun to ride a twisty back road that way......

I removed the canister to allow for the fitting of crash bars......and because it ugly.......

True in the twisties higher RPM is desirable. Most of the MPG figures reported here are probably taken while commuting though. In that case no matter what bike I ride (except the Ninja 250) I am in top gear as soon as feasible. There is just no need to rip around at 8000 rpm. The kids on 600 SuperSports crack me up riding around at 9000 rpm so they have some power. :D

As far as ugly, man you can take the wart of the hogs butt but its not gonna make its butt any purtier. :)

Versys with Canister = Ugly
Versys without Canister = Still Ugly

:cool:

High RPMs use more fuel. If you think you have a problem try riding a tank of fuel at 4000 or below RPMs and see what it is. If it is still low, then you have a problem. If it is in the high 40s then you are just having too much fun on the bike. :)

high 40's not my bike its never gotten better than 42 mpg and now its down to 35 mpg.....guess I will have to start riding like and old lady to get any mileage out of her... I get that kinda mileage on my 1200cc v-twin Norge....would like to at least get 200 miles a tank....

does the mileage get better as the bike breaks in more... its only got 1800 miles on it....probably the way I ride, the same reason I only get 5000 out of a rear tire when others get 10,000...

High RPM

Its just plain more fun. 5th gear 5,000 rpm is about 60 mph. Where I spend most of my time. My bike gets the same mileage using 5th or 6th. I check it tankfull after tank full. It makes no difference. I can't get over 50 mpg no matter what I do and its usually around 48. At 5,000 and up there is no vibration. It really smooths out.

4th gear is 6,000 rpm 60 mph 8,000 rpm, 80 mph. Hang on at 9500 it gets there quick.

Think of it as a cat on its toes ready to pounce.

Stock everything

My Fuel injected BMW gets better mileage in a lower gear.

I would look into this problem a little more than worry about mpg. The over fill spout is at the top of the tank near the the fuel inlet and should not come into play with only half a tank. You may have a fuel leak along the line somewhere. 5000rpm should not be that large a factor, maybe a few mpg's but not down to 35 especially if your bike is runing fine.

Here are my MPG figures over the last few refuels: 57, 53, 49, 48, 50, 55, 48, 56, 58, 54, 56, 56.

Mixture of city riding and a couple of bigger trips. Stock standard bike.

fuel ecomony should increase as the motor frees up not decrease, i presume you have takin it back to dealer for a tune up or check, there could be many issues plugs, efi, faulty muffler the list goes on... if its your ridiing style easy to check fill it up do a 50km loop and refill and see what you get, then do it again on the gas riding like you normally do, i find theres not a great difference around 340kms a tank even 2 up.

35 MPG is a complete joke - there's a serious issue there. I can't add to the suggestions made but I can report that my '11 will return 45 ish when ridden 'enthusiastically', 50 ish when going with the flow on A and B roads and 55 ish on a steady motorway (freeway) run at 75-80 mph.
