Hi everyone, i just picked up a 06 yz450f last week and all week i been having some new stuff coming in (tires, bars, etc. While i had the bike apart i look it down to clean it really good and took the brake line off the rear caliper. Well i was not thinking when i went to put the swing arm bolt back in and pushed down on the rear break foot lever. I have tried and tried to bleed the air out of the brakes. I have also filled the reservoir back up to make sure its not empty.While i have the bleeder screw open im pumping the foot lever but no fluid is coming out. Any ideas on why i cant get no fluid to come out? And for my second question what do people recommend for oil Full synthetic? semi? Conventional? what brand? Thanks!
