I worked on my 2000 yz 426, I installed a White Brothers E-series pipe, and new Chain and sprockets, went from a stock 14/49 to a 13/50. I changed the oil and oil filter before riding and noticed some metal shavings in the filter, not too big of a deal, small shavings. Well my new pipe has been billowing out blue smoke when I reach around 7000 rpm. I powerwashed the bike and now my exhaust cam is stuck open and I can't get the bike to start and I don't know how to shut the cam and I was curious about the smoke. Please help, THANK YOU soo much everyone in advance.
