75 750k Dyna S

I am bit confused on the Dyna S instructions on setting the timing. I am aware of rotating the magnet to full advance then setting the advance timing. I understand stock points the full advance falls between the two advance marks highlighted in blue. Per Dyna S instructions "the right hand advance mark for cylinders 1-4 should align with the fixed mark on the engine case"
My confusion is that there are two marks to the right of 1-4 two blue highlighted marks. Currently at 2500rpm the 1st mark one closest to the "4" aligns with the engine case mark.
Is it suppose to be timed to the mark closer to "4" #1 or #2 in the pic below. thanks

Just get 1-4 to match 2-3. I used the mark furthest to the right and my bike runs amazingly. Set it, forget it and don't sweat it.

Thanks for quick reply. So you set it to the #2 in the image. I have about 150 miles I did the whole engine rebuild and something simple as this timing got me.

Yes, the blue mark in your image furthest from the T and F marks. As long as both cylinder pairs are the same, you are good.
