Guys brought myself a set of 04 yz450f cams for my 01 wr426, question is can i use both the inlet and exhaust or is it pointless, there is nothing wrong with the inlet cam (original) just thought id ask if this could be done and if there are any benefits,

also can i use a 450 cam chain to replace my stretched wr426 cam chain im guessing there may be difference in height engine wise but info appreciated,

Last but not least should i be checking my valve clearences with WR426 specs or yz450 specs?

Hope someone can give me some info
Thanks in advance,

Valve clearances should be the same no matter what cams you use.
