I watched as Grant and Chisholm's mechanics completely strip down their bikes after the race. Parts in one box, frame off to the side, and motors put aside for rebuild. They were going to put another motor in for the next race, and do a complete rebuild on the ones they ran for Red Bud so they could go in for the race after the next one.
speakin of how they strip the bikes down, it sucks to see how many parts just go to the trash. I seen them drill holes in an exhaust bend it and throw it away, drill holes through used tires (by used i mean one moto), they destoy parts. i rememer one year we managed to get a sproket from one of em before it was gone.
