Lost my fuel milage

[cmc1698g]

 When I first got my valkyrie  it would get around 36 mpg
Now I lucky to get 28 to 30 mpg
It's a 99 with 22,000 miles

   Contagin of the twisty thing. It occurs after a short ownership.

those ninja 250's get about 100mpg. personally, i would much rather ride my valk which seems to be around 150 miles per fillup.

but, if it bothers you, clean the carbs, change the air filter, polish the intakes, replace the intake seals, make sure theres no vacuum leaks...etc...then in the words of daniel meyers and others ride it like you stole it

[Michvalk]

Changed the air filter? Running different fuel? What do the plugs look like? Vacuum leaks? Could be a ton of things, or you could be twisting the throttle more

Well, if its lost just retrace your steps, you'll find it.
You didn't mention doing/changing anything. So, I'll assume its right wrist related.

Might want to check ur tire pressure too.....minimum 40# front and 42# rear

I have found that poor fuel mileage, other than wind and rpm, is usually caused by a dirty air filter.  Some folks completely forget that it it needs service just like an oil change, tires, etc. etc. Hoser

Right wrist syndrome OR we say-twistin her tail and makin her HOWL!!  RIDE SAFE.

Also do a vacuum leak-down test on the petcock...a failing petcock will (contrary to surface thought) dramatically reduce the mileage.
