This is from the FAQ at the top of the forum.....
i have heard that wr450s come out stantard with the cam retarded and you can move a tooth one way or another to make them go better is this true can anyone help me out
Q: How many link pins are between the cam marks for YZ timing?
A: If you have a 400 or 426, you will need to rotate the exhaust cam sprocket 1 tooth clockwise at TDC. This will give you 12 pins between the marks, stock is 13. If you have a 450, you will need to buy a YZ exhaust cam as the rotation method does not work due to the decomp pin.

YZ timing pin count if you use your WR cam is 12, if you use a real YZ cam then it will remain 13 pins.
