Early last summer I installed $6.00 Daichii points on the 750F. At about 1000 miles I again checked the advanced timing with a strobe and found the timing to be slightly advanced, not where I had set it and not noticeable to me when running. I reset again between the advance marks with the strobe and 1000 miles later I checked and the same, slightly advanced. 4 times I did this.
Is there a logical explanation? Thanks, Dave
