I have read many posts about how people yz time there bike. I have also read some conflicting threads on the whole exhaust cam 1 tooth clockwise. From what I. undertand, yz timing is 12 pins with exhaust at approx 1 o'clock and intake flush and wr timing is 13 pins with both exhaust and intake flush with head. Can anyone tell me for certain if this is correct? I would love to see pics of yz timing and stock wr timing. I think my 99wr is yz timed but the more I read the more unsure I am.
