Fuel Mileage...EEEK!
 

I finally installed a Trail Tech Vector on the '11 250 6D, so this weekend I ran it out of gas a couple of times to see how far she'll go on an OEM tank. The answer is: not far enough!

First tank I made it 28.5 miles before I had to switch to reserve. With tank #2 I made it about 27 miles, but it was not filled to the brim. Looks like I need a bigger tank for enduros. I didn't feel like pushing the bike so I didn't run reserve clear out. I doubt you'll get more than 6 or 7 miles out of reserve. I ran about 5 miles on reserve and it was about an inch from going dry.

Now having said all that, I have not confirmed my son's programming of the Vector by checking it against a known distance. I'll do that before I go into a panic.

Regardless of the fuel mileage, I LOVE this bike!

Dang, we get just under 40 miles on the stock tank with our bikes (and I'm pushing 300lbs). Any chance your float level is a little high and sloshing fuel out the overflow tubes while you're riding? That was happening with my kids bike when we first got it and his mileage was about the same then as you are getting.

You have a problem. All three of my 250s went at least 45 miles on a stock tank before reserve, even more going eaiser trail riding. Yes, check the float height first.

I made some queries about the float height on the as2 carbs that the 010's ans 11's are now coming with. Even the pro's like JD and ES dont know. The best shot I've got is 6.5 to 9 mm. In the case of the newer carbs the old 16 mm at 65 degrees no longer stands true.

In addition to what has been said, rb designs head work noticably improves efficiency and throttle response. Glenn had some numbers in tight stuff that I don't recall.

Jetting also helps and the stock jetting isn't doing the bike any favors.

For float height level has anyone called sudco?

Jeff

They Sudco told me 16 mm, which is Impossably high! the point being they dont know either.

If it pees on your foot when you tip it set the level lower in small increments until it doesn't.

Right foot or left foot?:D

It's not peeing on me and I'm not seeing or smelling gas. I'm betting it's an invalid calibration when my son set up the Vector. I'll put a helmet on and check what the odo says after I go down my driveway and back (.9mi.).

Put your right foot in
take your right foot out
put your right foot in and shake it all about
:D
