APE - Adj Cam Sprockets installation on kz900???

While packaging my new CAM's and sprockets for shipment to Larry C., I noticed the new adjustable CAM sprockets don't have alignment scribing on them but DOT's on them instead.
The intake DOT matches the 28 pin (tooth marking) but the exhaust DOT sits at 12:00 whereas the OEM have lines to match to the head horizontal axis.
Most probably a question for APE Jay but does anyone have the alignment/installation instructions for a KZ900?
NOTE: I can get it close by comparing to the OEM sprockets but just curious on the fine tuning aspects regarding the "Adjustable" slotted sprockets.
Thanks,

Never mind this part of my posting, got out the trusty Ole Kawi Shop Manual and answered my own question...DOH! :whistle:
See, never too old to learn something new everyday....
OMR ponders.... Did I change my shorts today? :S

Larry is doing the valve job and CAM sprocket settings so I'm not worried about it at all, just curious for installing the sprockets are not a big deal and will be real close in comparing to the OEM alignments. Just wanted to educate my mind and expand my knowledge.
I was just more interested in reading or hearing from others on the fine tuning/alignment with the adjustable sprockets aspect of it.
APE has instructions for other non KZ bikes... I'll keep searching.

The trickiest part is getting the dial indicator tip to not drag on the cam, not touch the lifter bore and repeat readings. I have one I ground down very thin that works perfectly.
The math is easy. Here's a shortcut example to get lobe center.
IO 25 BTDC
IC 53 ABDC
(53 - 25) + 180 / 2 = 104
Same method for exhaust cam.
Do the cams when you can work undisturbed. Take your time. It's not difficult.
It goes much easier if you assemble only 2 valves in the head with light springs. Get some at the hardware store. Bolt the head on, torque it, install the cams in the middle of the sprocket travel holes. When you're all dialed in, remove the head and then install your normal valve springs, then assemble the rest of the motor.
