Hey, hi all. Has anyone out there had any experience, or luck, in bogging up holes in an XR head? My XR600 has a 5mm hole in the head on the front right side, between the second and third cooling fins not far from the header clamp bolt. I'm thinking of giving it a complete clean, degrease and dry, and then using a bog such as an exhaust putty or some kinda epoxy, any tips in fixing Ol' Holey, and smokey... and ol' pain in the butt. Thanks, p.
