Has anyone ever installed zerk fittings on the rear swingarm for the pivot bolt and the linkage. It looks like i have a seized up pivot bolt. I tried beating the thing out and its not moving. I sprayed the hell out of it last night with wd40 to soak in, im going to try to use my air hammer to push it out tonight. In the future i would like to be able to have some zrks to grease it and the linkage. Does anyone make bolts with zerks on them? anyone have any suggestions on removel also?
