Hey guys just wondering witch would be faster in a drag race 1st gear all the way to 5th gear? He doesnt even know I have the bike yet till we show up camping and we both know how to rip though the gears. Ill list the mods......... 2002 YZ250F 1. Exhaust 2. Uni filter 3. spocket.........i dont know how many teeth but he put it on to give him more top speed rather than acelleration. 1999 YZ400F 1.Uni filter 2. top removed off airbox 3. FMF PowerCore 4 exhaust those are hust the power mods. We both have bars frame and under gaurds, new 739 tires, and grapics< i know that that dosent make a difference.lol :canada:Witch one would be faster? :excuseme:Do you know of any more "free mods" I can do?
