Moe says he removes the plugs and raises the rear wheel off the ground. He then puts the bike in gear and rotates the engine via the rear wheel. At least I think that's what I read. The service manual tells you to remove the right engine side cover and turn the engine using the bolt on the end of the crankshaft. That requires removing the foot peg bar and draining the crankcase.. a new side cover gasket will also be required. Me? I bump the thing over using the starter... this isn't exactly the prescribed method but it's the simplist for me. I just barely tickle the starter switch untill the cams rotate to the desired position, take my measurement, write it down and move along to the next one.
Once your measurements are made and you make the necessary changes, reinstall the camshafts assuring all your marks line up and the manual says to rotate the engine 360 degrees and recheck the timing marks. At that point recheck your clearances.
I've done mine a couple of times now and that's what works for me.
