who sucks more gas?????

Ok everyone! here is a question. how much more gas does, say a crf 450 consume more than a crf250.
Now you dont have to be acurate, it would be nice to know, but lets hear some sinareose. i would like a Ball park estimate. And if you would also like to answer another question, you may.
Do you normaly jet up when you put on a bore kit? i would love to rob some power out of my 250 but it sucks a lot of gas as it is.

Most of our crew own 450's but I race a CRF250. I haven't noticed any difference to speak of. We race for two hours.

I have noticed that most of the guys that I ride with can ride almost all day on a 250F with one tank, but the guys on 450's fill up at least once. I use ALOT of gas when I ride, more then almost everyone I ride with, I think its due to hauling my big butt around.

I have learned that you generally have to lean out your jetting when doing a big bore due to volumetric efficiency

I'd have to say my 454 sucks more gas then that 450...
