While removing my stator I decided I would upgrade to a Hayden M6 Primary chain tensioner. The OEM screws must have been put in with red lock tight I got the bottom one out but the top one will not come out. I try heat from a propane torch, I tried a chisel to turn it(after the screw stripped of course) and I have tried easy outs. Now I am thinking that drilling it out and putting in a helicoil is about my only option. Anybody got any other ideas?
