2005 WR 450. Got a brand new factory flywheel installed. When I look at the markings on the flywheel for top dead center there are 3 of them. Three vertical lines all spaced within about a quarter inch.

Which marking do I use?

the line , the other two has a horizontal line between the two and makes a H

i believe the singe vertical line is farthest right .

or at least that is how my 450 is .

Thanks Brad,

Went down and looked at the marks, there is an H in there. When the mark to the right is in the window the cam marks line up.

Its just Japan saying "HI" :-) I believe the other mark it used to verify timing when using a timing light according the my manual.
