I've got an 02 wr426, and am wanting to put the yz tank and seat on it. My only concern is how long I will be able to ride before running out. Do mainly trail riding. From what I've read all I need to do is get a yz4xx tank and seat, correct? Or do I need the radiator shrouds as well. I have already gotten rid of the lights and such on my wr, has yz fenders. I want to switch to be able to get farther forward on the bike, but at the same time don't want to be running out of gas on the trails either.
