Hey I have a book for a 2010 yz450 but not my 2011. My question is if the valve clearances are the same on those bikes? My 2010 book says Intake: 0.10-0.15mm and Exhaust: 0.20-0.25mm (if i remember right). Mine intakes are 0.06mm and 0.08mm and my exhausts are 0.12mm and 0.08mm. Just wanted to make 100% sure they are the same before I go re shimming. Thanks in advance!
