Default How to set timing???

first 2000 883 converting to cams, big valves...

I am putting it back together and need to set the static looks like there is a LED on the (stock) ignition module for this....I have the manual for the bike....there are 3 marks on the crank first has one dot second has 2 dots and third is a vertical slot ground into the crank....which mark do I doesn't say anything about what mark or the light on the module (unless I just can't find it)...

thanks, guys/gals

I had a look in the manual and it does not tell you,for 1986 to 1994 it shows one dot in the window,and for 1995 to 2003 it shows two dots,not much help but i would go with the two dots if i was doing it.

The dots are front cylinder advance marks. Those will be no good as you need slightly retarded ignition timing on a 1250 build (28 to 30 degrees max). The easy way is to just back off the timing by rotating your module a little bit and take a guess at it. The best way is an upgraded module that is set to a 28 to 30 degree max and and can be timed on any Sportster crank regardless of 883/1200 advance marks.
