hi all. i have a 2004 yz450f i ride in all weather conditions,100 degree dust to 30 degree wet, i have noticed when i ride in the wet my oil filler cap will have a white spooge on the underside of it. if i pull the hose off of the valve cover i can see evidence of mud,water at the top of the pipe. if i ride in the dust i see evidence of dust at the top of the pipe. i would like to modify this and after a through search of thumpertalk i see that several people have done mods but i cant find any pics. has anyone done this mod? has it worked in the long run? any pics? thanks in advance for all the quick replys. www.freewaytrailer.com we offer tt member discounts!
