I 'm pretty sure that between the 12'o clock punch marks there were 14 pins.
After stuffing in the YZ cam with 14 pins between top marks (easier to count)
the 9'o clock and 3'o clock marks well appear a little submerged.
But considering the &%$#@!ed up EFI Engine accessability they might be meant to be viewed slightly from above?
Anyone got experience with a '06 YZ cam in an '12 WR head?
Are the 3'o clock and 9'o clock punch marks to be viewed exactly from the side?
Should they really both be flush with the cylhead surface?
edit: sorry my bad. when done right them punch marks are exactly at cylinder head top surface height
when the crank ist at TDC, if you stick your finger into the cam chain tensioner hole and eliminate the slck in doing so.
