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.
