This might work ??

I'm just reassembling my 93gs, the right swing arm bearings failed . Bone dry and in pieces before I got home . I read the insanity of bearings acting as breathers for the cast swing arm . Does that not mean there's air where grease is supposed to be ? I packed the hey outa the new bearings before installing them in the swing arm . Then smeared a bit back of the bearing . I previously drilled a 3/32" hole on the bottom of the swingarm, on the FD end, center of the boss cast there for a drain plug . I put a 1/16" brass cotter pin in the hole and spread it out . Rain water won't enter, if it gets submerged, I pull the FD rubber boot off that night . Why the SW would develope pressure is beyond me, but the 1/32" air space at the cotter pin should " breath". I just hope it doesn't "suck" air . The driveshaft, FD bearings, and SA bearings are an anual ritual with this MC . Having one or the other fail every year, or about 25k . I figure, when the greasable driveshaft needs grease . The FD bearings can be greased . Now I can use my finger to repack the SA bearing as well . Maybe it will become an ongoing maint schedule or I'm hoping . Has anyone done this, or have a comment about it ?
