timing on a yz 400f

whats the diff between using the I on the flywheel or the H when setting timing. ive used the I like the manuel says but what if i used the H.

thanks shane

Your bike's timing would probably be off and may run like crap. Sometimes the symptoms may seem like your jetting is off when you don't time it right.
