cfire7818 Posted April 10, 2010 07 crf450r. have greyish transmission fluid with a greenish tint when i drain the transmission. the bike does spit out a little bit of antifreeze from the overflow tube but the weep hole is dry as a bone. do you guys or gals think that maybe this could just be as easy as rebuilding the water pump or as difficult as cracked water jackets. also i am running 10W40 oil in the transmission as the book recommends but that seems a little light for that engine and was wondering if you guys run something a little heavier in you bikes. would would greatly appreciate you input. thank you Share this post Link to post Share on other sites
