Did I do the YZ cam conversion correctly?
Posted May 06, 2005 - 08:19 PM
If I place the upper punch mark on the same place in the chain the old one was located, the lower mark is not placed correctly on the case.
Here are some photos of what it looks like installed.
Can anyone advise me on this?

When installing the YZ cam, there should be the same number of pins between the top marks, and the marks on the case should line up the same way as stock.
As far as the number of pins between the marks, the 250 has 13. I'm not sure about the 450. When re-timing an '01 or '02 to YZ timing, you move it from 13 to 12, but that is when you are not changing the cam itself.

Thanks for the advice; I guess what I'm saying is that I have to choose; they marks on the case can either line up, or the upper marks on the pins can line up. Not both.
Did my photos look like it was correct? Or Incorrect?

Little confused still ; this post says 14 dots:
And this one 13:
Anyone know what the stock count between pins are on the YZ450?

I just looked at a manual from a 2004 YZ450f; in the diagrams in valvetrain and cams it shows 14 pins between the two marks. Unless they just use generic diagrams for all the manuals, then that would put my exhaust cam lower pin below the case...
