Timing - Index Mark? 01 to 03 Auto-Decomp Upgrade

Recommended Posts

So I finally purchased the 03' Cam for my 01 YZ250F. During the installation process, the manual instructs you to check the timing by finding the index mark indicatiing TDC and line it up while the "dots" on the intake and exhaust cams are also lined up at the edge of the case.

Well, the mark in the book is not what the mark on my bike looks like. It looks like an H and an I. Where is it supposed to bet set at? I know that piston is at TDC when it lines up with the first line of the H.

Any thoughts or comments would be greatly appreciated!
