Has anyone had any problems with overheating on slow tight trails? I have done all the free mods except for the airbox and I have not rejetted. I have a 06' WR450F.

Yeah, I read about the bike running lean. I just didn't think it would boil my antifreeze out. When I returned from my ride, the reservior was empty and I had lost 1/3 of the antifreeze in my radiators. Not having opened up the airbox, I didn't think it would run much leaner than stock.
