What else did you do when you changed plugs? I'd look for obvious things that might have been disturbed or disconnected. Like vacuum hoses and the like.

Or just lay off the throttle man! I know It's fun but jeez! Lol

If that was all stop and go that seems about right for a heavy wrist. Do you fill up with the bike on the side stand?

Wow, somethings not right, that's around the mileage I get on the track!

I might of possibly had a heavier right hand lol;) still tho seemed way worse I'm guna try another tank full and see the mileage.

I fill up sitting in the bike straight up and down every time stuff it right to the neck if the tank.it was mostly city but I still usually get in the mid 90's to.about 100 miles till the fuel light comes on.could spark plug falling change fuel milage that drastically?
