Hey guys,
I finally got my bike running (sorta). I am having some issues with timing, I have a 1975 with a rephase, pamco rephase ignition, Hugh's cam, and the crank was done at a local machine shop.
I just re-installed the whole electronic ignition unit as per Hugh's guide.
I will try to explain the problem as best as I can. I have scrolled through the rephase timing threads already and could not seem to understand/apply them to my situation, thus the new thread.
I got the bike running and started to dig into getting the timing correct, so I got out my timing light and started to rotate the pamco unit so that the mark on the alternator line up between the lines that are on either side of the "F".
Also... I measured the temps of the exhaust pipes, the right cylinder was consistently 100*F colder than the left one, assuming I advance the timing 30* to the fire mark, I think that should retard the left cylinder (thus lowering the temp) and advance the right cylinder (thus raising the temp) and the temps will meet at some common point?
I managed to get the mark to the line that is slightly before that (see picture)
I can not advance the engine anymore to get it between the "F" lines because I am maxed out on the slot on the pamco unit... I have been tempted to just dremel out a larger slot...
I found out that I am 30* off from where I need to be by making the timing light 30* advanced. when I adjust the light to 30* advanced the marks line up.
any ideas on what to look at next?
