Hello, I recently installed a generic electronic ignition from 4into1 on my '74 CB750K but it's not advancing as it should. The plate has been dialed in with a timing light so the F mark is perfectly aligned for 1-4 and 2-3. The problem is when I check it for advance at 2500 and above RPM it only advances halfway. The issue is also noticeable on the road and what caused me to look into it and find this issue. Checked the advancer and it opens and works as it should and is the K1 300 version. I've heard of some people setting the timing to the advanced marks at 2500+ rpm vs the F mark at idle since little time spent at idle vs above 2500 rpm. Any suggestions? Thanks
