Hello guys. Bought an 2008 yz450 and I have a few questions. I've rebuild a fair few of these bikes but first time adjusting valves. Now I am confused as to why nearly all of my valves are too tight except for one valve being way to loose Specs are : intake 10-15 . Mine are at .25 , .7 and .12 Exhaust spec : .20-.25 . Mine are .17 and .13. My question is understandable most are tight but why is one of them loose? Is that normal? And how far out do they have to be before it because a pain to start. This one takes at least 30-40 kicks before it does. Thanks guys!
