i know there has been many threads discussing this already but can't seem to find any posts that answer my questions. so, here goes....
1975 cb550 setting up the point following the manual seems very simple, but trying to see when the crank turns until the point contact opens widest could be tricky to the eyes. after several turns, i notice that when the points open up the most, the crank is at 15 degrees ATDC. so i used that as a reference to adjusting the point. someone please correct me if i'm wrong. manual spec is 0.3mm - 0.4mm. do the same procedure for point 2-3.
