fuel range

[rbm33]

im wondering what some of you are experiencing on your fuel range.
i have a 2011 300 six days and im getting right at 40 miles per tank, thats on a single track running a pretty good pace. our race season is about to start up and im just trying to figure out if im going to need to schedule a fuel stop or not.

I had to go to reserve at around 41.5 in a race yesterday, so I am guessing 43-44 miles tops on my 2011 250 Six Days in race conditions. I haven't changed the jetting from stock, just lowered the needle.

Install a needle with a fatter initial/root diameter will help you consume less fuel.

I went from the F diameter as in the stock N1E"F" to an H diameter. I run an NOZH top clip with a 42 pilot in my '10 300.

I get much better mileage out of it, both in tight and open trails. Since there is no accelerator pump to waste fuel like on a 4 stroke, the needle diamter plays a large role in how much fuel passes that portion of the needle when you are in the lower throttle ranges.

RB head mod was good for an extra 5 miles per stock tank on my 300.

I used 6 liters yesterday to go about 32 miles at trail ride pace in tight single track. Stock needle 2nd slot 40 pilot 172 main. spent a lot of time in 2nd below 1/2 throttle. I have a 38 pilot coming, maybe I'll look into the nozh ....... 11 250 6 days

2010 300

38, N3CH #2, 175 and float level adjusted.

70 miles on a stock tank. However I ride mostly 2nd gear tight stuff and I am not super aggressive with the throttle

2011 EC250

40 pilot N3EH needle 2nd from top 175 main

bike is jetted crisp


mixed riding 100kms range max (60mi)

42 N3EW#2 175/178. Lugs well. Punches hard in the mid range. Rips top!

Todays consumption 5L for 60KM. Generally I get around 10KM/L though so as above. Around 100km from the tank.

thanks for the input, i am surprised at the differences in ranges that everyone is experiencing. most of the races that we do here are around the 40 mile range, so maybe with a few little mods and focusing on riding smooth and not wasting a lot of fuel maybe i can make it without a fuel stop.

one more question.... has anyone tested to see far they can run on reserve???

thanks again for the input

Or........how far did you have to push your bike after you learned the hard-way how long it takes to use up the reserve.
