How do I lubricate the swingarm linkage?
Jack up the bike so it is fully supported, and the rear wheel is just touching the ground. Remove all of the linkage bolts. Note that, to remove the main swingarm pivot, you must also remove the engine mount bolt above the pivot. You will need a big breaker bar, liquid wrench, and possibly a propane torch to loosen the bolts. The bolts may also be stuck in the pivots due to corrosion. You may have to tap them out with a hammer and drift pin. Pack the bearings with grease, and reassemble. Before reinstalling the bolts, coat them with grease to prevent corrosion. You can avoid this mess in the future if you install zerk fittings for a grease gun; Watt-Man has the procedure on his site.
