well... origanlly i was gonna do all of the power mods and stuff for my engine this winter... but then i got to thinking... that isnt going to help me win this summer at the motoraces... just make me faster. and thereis plenty of unused power in the kfx400... so..handling and suspension.. i was thinking of getting a wider axle do you guys think +2 or +4? and i was gonna get some RAZR tires for the rear. i know those arent ideal for the mototrack but i dont race that often and wanted a good trail tire also. i figured the RAZR was a good choice there. and then i was going to get +2 +1 a-arms with works shocks triple rate with rezzies. what do you guys think? got any better suggestions or some advice or somewhere i can get a good price on this stuff?
