This is from the FAQ at the top of the forum.....

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.

I have done this mod to my WR and love it. My suggestion to you would be to find a YZ exhaust cam instead of rotating your WR cam. That way the number of pins stays the same. If you can find a YZ cam, I can give you a few pointers to follow to make it easier. If you simply rotate your existing cam one tooth (clockwise), you will lose the auto-decompression which will make it so your e-start really struggles if it works at all.

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.

Rotating a WR cam (450) to give you YZ timing doesn't work. If you want YZ timing, get a YZ cam.
