YZ250 Gas Tank Question

[encinitas]

My son will be racing a 45 min. moto at Cahuilla MX this weekend. We have a Clarke 3.2 gallon tank will he run out of gas??? The longer races are new to us as he races MX. He is a  intermediate rider, riding a stock 2007 YZ250 with a ProCircuit Pipe, 180 main jet.

Thanks for any advice.

I would think that 3.2 gallons should be more than enough to last for 45 minutes.

You could probably get a stocker to go that one
