Slabside Shovel Timing marks '67
So I've been getting this old girl roadworthy for a few months now.
20k original miles, pretty well unmolested!!!
I know I've seen talk of it before, but there's a timing mark with a line and a dot, and one with just a line.
I'm assuming the line is front advance, and the line + dot is top dead center front.
Is this correct?? The line+dot is throwing me and I can't seem to find any info on it scouring the web!?!?!

Re: Slabside Shovel Timing marks '67
An easy way I sometimes do it to avoid confusion. Takes into account that someone may have changed the wheels at some point or that whatever manual you may have could be wrong.
1) Remove spark plugs and timing plug
2) Rotate engine by hand to TDC on REAR cylinder (you can do this with pencil if you like).
3) While watching the timing window, rotate the engine *slowly* forward (same direction as when running) until you see a marking in the timing window. This is your ADVANCE marking. It only takes 10 degrees of forward engine rotation to get from rear TDC to front ADVANCE.
Write what you find down in your manual for future reference.
If your primary is still closed up, you can rotate the engine as needed by putting the transmission in third or fourth gear and bumping the bike forward carefully.
