Valve check procedure...

Front cylinder
F mark lined up on the rotor at TDC means front cylinder cam lobes facing up and leaning slightly outward.

Rear cylinder
R mark lined up at TDC means rear cylinder cam lobes facing up and leaning slightly inward.

To remove cams for adjustment...

F mark lined up front cylinder at TDC as before. Timing marks should line up on front cylinder. If not rotate 360 degrees to F mark and check again. Take out the front cams.

This is the counter intuitive part regarding the rear cylinder...Rotate the crank 360 degrees until the F mark shows again. The rear cylinder timing marks should now be lined up. Remove the cams.

Note.. The R mark is not used during removal or installation of the rear cylinder camshafts.
Been wondering, how comes when adjusting and removing the cams you have to have the mark on F and not R? Does it matter if you have it on R and remove the cams?
