1982 GS450 - dynatek - advancer/timing help - what each marking means?

[bren]

I just finished installing a dynatek ignition system on the bike (model #DS3-3C for posterity). Everything's looking good, i'm getting good spark and all.

Now I need to set the timing, and I'm not able to find much information on what the markings mean on the advancer unit.

Looking at the lobe for the right cylinder i have: "TI IF R I"

Now the instructions say: "While holding the rotor in the fully advanced position (clockwise),
slowly rotate engine forward until the light turns on. The right hand advance mark for the L
cylinder should align with the fixed mark on the engine case.​"

I'm going off of the right cylinder because it's the one with markings on my bike.

So now, which one is the "advance mark"?

here it is set up, i believe set lined up to the 'F' mark

alright, nevermind, i finally dug it out. T is tdc, F is fire. the mark at the end is advance. the "I's" are the timing marks.

I got the plate set, she fires and runs. I was able to actually sync the carbs and stuff finally and get her running right. Still backfiring a bit in the 2-4k range, so still need to finish the carb tuning and stuff, but i'm very close to riding!

The most important timing mark to dynamically align with strobe is the fully advanced.
