Gas Mileage?

(1/4) > >>

dezracer:
What kind of gas mileage are you guys getting on the KX500? I rode about 30 miles of single track and burned around 4 gallons of gas.  Granted I spent most of the day in 2nd gear.  Is this normal?  My motor is pretty much stock with the usual aftermarket reeds, pipe and silencer.

gowen:
I can normally make it a full day of mainly WOT before running out of gas. Assuming I'm on a full tank when starting.

mikesmith:
That sounds pretty bad to me,Id check my jetting (as Gowen can tell you jetting on the 500 is the best bang for the buck,but you have to spend some time on it as temps/humidity and altitude change) and your float level(I run mine a few mm higher than the book suggest)also I made a home made "power now" wich helped a lot.

dezracer:
I started with the Team green specs and went from there with the jetting.  Right now its set at:

55 pilot
2nd clip position
168 main

Runs like a champ, a little bit of spooge.  I think it may have just been the terrain.  It took us almost 3 hours to go 25 miles.  Nasty stuff, but the 5hundo shined. :)

gowen:
dezracer, 25 miles and 3 hours is still pretty bad milage no matter the condition. But, specs or not I am at a 38 pilot and a 148 main jet and don't even remember the needle. But, if you work with the jetting, you'd be amazed at the diffrence in power.. Hell I thought my KX was pretty d**n fast , and every time I made a jetting change thought that was it. But, about a year later I'm out and about.
