Hey all -
This actually happened about six months ago, but it still bothers me.
My 1980 KZ750 twin weeps oil from around the head gasket. It still has good compression (180 psi) on both cylinders but I wanted to get rid of the leak. I pulled the valve cover and cams and stuff off and got to the "blind caps" - circular plugs that cover up the head bolts - and two of them were stuck and I couldn't get them off.
Oh well, waste of six hours in the parking lot (yeah, I work out of the back of my car in the parking lot..)
How can I get these out? I tried tapping them with a hammer, twisting really hard, etc...
