Crap.You cant even begin to guage it.
My 310Z will drink a full tank around 3 gallons in about 30-40, 300 feet drag passes wide open.
My ported R will drink almost a whole tank in about 16 miles of rough trails.
The 70 and 90,crap.
I will run both of them for a month before they need gas.Each one will get about 10 hours out of a tank.
Who cares.Fill em up and ride.
When in doubt,take more than you need.Some bum on the trail will always need some.LOL.
Or start a toasty fire!
Here is where my long useless list of stuff nobody cares about should go...
