I seem to be having some difficulty getting the correct installed gap of 35-45 thou. When I measure the gap appears to be correct but the clutch slips badly. I took the cover off and the installed gap changed which explained the slip. Before you ask I did use the two feeler gauges as per the instructions. The other thing I noticed was the spring tension on the external adjuster slacked off after the test ride. It would appear to me that something is hanging up during the installation. Any ideas?
