Rotate the crank 360° and the rear is back at TDC.

I know I am right. Of course there is a relationship but the more important point is that if the timing marks on the inner cam sprockets are lined up, that realtionship has been set; FOOL PROOF. The next time you post something on this forum, you shoud drop the attitude; not well received here. Bye Bye.
