The previous owner of my CB550 installed a full Dyna 2000 ignition on it. The one that not only replaces the points but also get's rid of the advance mechanism and controls ignition electronically. It also has a few spark advance curve settings. Maybe over kill for this little bike but hey, it's already there.
I've got it on the advance curve setting it recommends, 25 degrees of span and full advance at 3,500 RPM, and it seems to run just fine. The manual for this thing is written in a kind of general way as it will work on several different bikes and recommends about a 40 degree BTDC firing position at full advance. My question is is this the correct setting for a 550?
'About 40 degrees' is a bit of a general term and a couple of degrees one way or the other probably won't hurt anything but I'd like to get it as close to right as possible.
Thanks for any input.
