Adjusting valves w/degreed cams

[Nessism]

Awesome! I have a buddy!

I also do not use the Suzuki values for tire pressure. And I - GASP - leave my petcock on virtual PRI for an hour or more while I tune/adjust the carbs. Worst of all, as soon as I get my pillows home I tear the tag off!
I guess I will be cursed to the halls of Honda-dom forever. Oh, the shame.

My comment was actually intended for Mr. Sarcasim (7981GS), but since you are stepping up and owning it, I'm okay with that.

That's O.K., Ed. We have always gotten along and will continue to do so.
It reminds me of a former boss, who only knew one way to do things. If you did not do it his way, it was wrong. I tried time and time again to demonstrate that there was more than one way to skin a rabbit. He was unable to see this, which is why he is now a former boss.
All I was attempting to point out is that the goal of rotating the cams is to insure that the lobe was not riding on the shim cup. There is more than one way to do that. Since this is a major job on my bike (speaking of the GPz) I want to make sure it is correct before I start putting things back together. So I double check and triple check the settings, and I also make absolutely certain that the lobe has no contact with the shim cup.
And I agree with your earlier comment about hot rodders advancing or retarding the cam timing, but I suspect that is not the case here. In fact, when I went to degree the GPz cams I read on the GPz750 mods page that drag racers had experimented with various timings and found the factory setting of 108 degrees to be the best.

Suzuki's adjustment method is really simple, and only calls for rotating the engine to four positions to adjust all the valves. This method places adjacent valves (or pairs of valves with the 16v engines) on the cam base circle so the adjacent valve springs are not pushing up on the cam and skewing the cam within the journal bearing clearance, thus leading to inaccurate clearance adjustment.

Yep. This is the RIGHT way to do it. Any other way is INACCURATE. There is a REASON for doing it this way, as explained above.
