250-500cc WR 300 Fuel range

Hey guys, I'm going on a 2 day ride soon and I am not sure what mileage the bike is capable of.
It's a 2010 model in standard form, apart from changing to a 14 tooth front sprocket. I am in Australia so if you guys could tell me the total miles out of a full tank rather than miles per gallon.
I know there is a lot of variables such as terrain, gearing, jetting etc, I am just after a rough idea.
Thanks
Marty.

I've done 70 miles on a tank. I have a lean tuned Keihin carb though. Stock gearing. This is on fast flowing mountain single track.

About 90Ks of tight technical queensland ranges, lots of low gears etc.

Hey windsurf, do you ride at Beerburrum? That looks like Mt Tiprogagan (spelling) in the background.

Yep it is. Also Amamoor, Kadanga, Yandina etc all the Sunny coast spots.

I have gotten as little as 40 miles when I was WFO in the desert to 58 miles when I was on tight mtn singletrack. This is before putting on reserve in both cases. I typically don't worry if I am going for a 50mi or less ride. If over 50, I bring extra gas. I like not having to ride back to the car on reserve.

it tight here I go by time not mileage...I get 2 hours with about 1/3 tank left.... and about 40 miles.... so I would say 50-60

70+ miles on a 3.4 gallon tank. '08 wr250. sucking vapors at that point. but then again, i'm a pretty big fella.

90-100ks inc res. im no featherweight either. rich jetting. 14t front cog. roughly 10km per L
