Joe, I didn't say that you advanced the cams, I was talking timing. Ten degrees advance on the cams wouldn't make one revolution. I didn't advance the cams until last fall. I listened to Sky because you hadn't done it yet. I did mine a bit different than Steve and I did it before you did. Check your emails. I have the emails saying your plan was to use a grinder and copy the pics from Steve and me. Which you did successfully. Had you posted your way first, I probably would have done it your way. Why? cause it looks too easy. To be clear I mean that as a compliment. I'm not criticizing your work or saying it doesn't work. I'm just saying C5 covers a whole multitude of sins. What works with C5, may not work with other set-ups.
To anyone else reading, and Slab, I was writing ATDC thinking of Ahead of Top Dead Center. I should know better. Sorry not thinking. Anyways the way I advanced the cams will advance the timing of the Dyna the same amount. So I am figuring that in, as well as the 5 degrees additional advance from the F marks of the 1200 flywheel. I am closer to the T marks than the F marks now by more than half, I am guessing 2-3 degrees ahead of T which with advanced cams puts the ignition at 5-6.5 degrees BTDC.
I do have a light and if I can fix a plastic pipe to put around the timing hole, drain a quart, I could get an idea of where I'm at with full advance. I've never done that on any of my bikes. So then my advance marks will need to be interpreted.....urgharah!!! 1200 is 45 degrees, 1000 is 38, but with cams advanced, hmmmmmm I'm getting loooost. It has a 1000 advance so total advance is 33 degrees stock, ( 38- 5 ). 1200 is 35 total advance, ( 45-10). If my timing is advanced 6 degrees, and I have tweaked the plate some, I should be near the 1200 advance marks on the flywheel to see the line.
Thinking it over, I might just throw the 105 main jets in from the 1200 again. The change in timing might make them viable again. In my experience with the 77 carb merry-go-round of jetting, I finally gave up on jetting and did the vacuum change to the slides and then ended up merry-go-rounding the jetting back to stock. My gut tells me it's going to need 120 like the Magna, but with the smaller runners it could be the 105's.
I appreciate the advice from anyone who can help me get through this. I have a pretty shallow mechanical background. To me this a challenge, but fun. I know the syllabus said there'd be no math, but... This modification throws a few curves at you.
