How long does a tank of gas last?

[LxMxL97]

Last season I raced a 400ex and I could finish a full length xc race. I know the lengths of races differ a little from place to place but I run awrcs cra and a couple gnccs and I was wondering how long a tank of gas will last in terms of laps in a 450r the motor is all stock except a stage 2 hotcam

I've got a stroker (471) with +1x4 valves and I need an exrea capacity tank.. I can make it but it's too close for comfort I hit reserve on my last lap and BARELY made it back to the pits

So you say that you don't need to pit and fuel up?

I'm new to the XC world so I've only got one under my belt.. My bike is setup for MX but I'm racing both XC&MX @ 50" lol..

I'm going to get a + sized tank this spring.. Last time was too close for comfort, I ran out of gas in a rut, stalled and got stuck and lost at least 2 positions before I could get started/unstuck... If I had the tank would have been fine I wouldn't need to make a pit stop to sure.. (I'm not doing GNCC though so the length of the race could be different..)

So you finished a race on a tank of gas.. how long was it?

Race, not in a long time and not on my 450. But I will say that I can easily ride a good day on my tank. Probable actual ride time is 4-6 hrs. I have to swap to reserve after a long day tho.

I was able to run 2 hrs on a stock 04-05 tank without worry. I run the 04-05 carb which I think is a little better on fuel than the FCR. A couple races were just under 2.5 hrs and also made it, but was real low. I think it really depends on how fast the track is, and your riding style. An A class versus a C class rider will use different amounts given the same machine.

To sum it up, Id say regardless of class, on an 04-05 tank you can get 2 hrs easy without worry.

I can get maybe an hour and a half on my race bike with a stock tank, but I'm special. I can finish a GNCC (2-2.5 hr) with a 4 gal tank with a little to spare. MOST guys can finish a 2 hr race with an 04-05 tank as long as it has the 04-05 carb and no rekluse.

So you finished a race on a tank of gas.. how long was it?
