I am running Amsoil on my yz 426 it runs outstanding with it! I can hear no engine noise no valve cliquing all the noise comes from the exhaust only! The problem is that every time I rid it I have to add a ½ curt because seams it leeks from the breather tub I wonder if it is because a synthetic oil? Are you running synthetic too? Does it happen w/ other brands of oil I never tried any other brand beside Amsoil synthetic!

Oil brand would have no bearing on the breather hose blowing oil.
