I spoke with a few old head mechanics. They told me my clutch cable adjustment was causing this issue more than likely. They told me to loosen it up a few turns and see if it fixes the issue if it doesn’t they’ll have to pull the cover and check. I didn’t believe them, figured it was clutch spring, or adjustment behind the derby cover so I took their advice and loosened it a little. Issue seemed to have stopped. I ran it for an hour on a backroad for over an hour back and forth and couldn’t get it to mimic the issue. For S&G’s I tighten my clutch as tight as it could go, and it did the “slipping” in every year as soon as I would hit the gas. They said start as tight as it can be and then slowly work you’re way to loose. I trusted the old guys and they were right.
