Static timing this thing. ( 1989 FLTCU 1340 engine) At front cylinder TDC I find the timing rotor windows a little clockwise of horizontal. Would this be front cylinder exhaust? To be front cylinder firing how should the windows be oriented? Nudging the rear wheel on newly built engine is a pain and I may be continually overshooting and getting the mark on the wrong stroke!

LOL, I feel your pain. Been there done that.
Yeah, the notch in the cam will be between 8:30- 9 o'clock depending a little on the cam, that's compression on the front. You really MUST get the wheels to stop on the mark to do the final setting. And if you go past the TDC line, back it up beyond the line and get to it turning flywheel forward. Makes a difference sometimes.
After running it a bit like if you're doing warm up cycles and waiting to cool, go back and check it again. PIA, but worth the effort for piece of mind.
Im determined to overthink this, but Ill use the notch as a reference. The way the windows on the rotor are just cant be right for the Dynatek. It doesnt have enough adjustment range to get an eyeball on those windows in that position. Pretty sure the cam is set right too. Pinion at 12 o clock, pinion points to mark on cam other cam mark points to mark on breather gear. Pistons at that time were bottomed out and valves closed.
plugs out, transmission in 5th or 6th gear makes it much easier to get the motor timed while working the rear wheel. Couple squirts of motor oil in each cylinder as well.

With the pinion/cam marks aligned, the front exhaust is (just) starting up, rear exhaust is (just) at closed.
DO NOT use the notch on the the cam or rotor to set static timing. If you're off low, not biggie, but if you get 3-4 degrees high, you're gonna be very unhappy real quick. Use the TDC line on the flywheel or use a timing light but that's real messy and frustrating.

well the valves seemed closed could very well have been close to opening tho. And I think I might just stuff that Dynatek in more or less as the factory module came out and see if the bike starts. I know what over advanced will act like so will be on guard.

It'll sit pretty much straight up when it's close. May end up a tick ccw from straight up. This is the first one I ever installed. It sat a bit counter-clockwise, most are so close to straight up, hard to tell.

thats good news!

This to set the crank to TDC using the plug port on the primary side of the motor with crank mark to start with, and since it comes with a LED to set the static timing on the unit,
Just turn the ignition on, start with the 2000I more counter clock wise which will have the red led light on, rotate it clockwise until the status light just goes out to set the static timing of the unit and lock it down.
