r inspection, the rear wheel bearing which replaced couple months back also suffered the same faith too....can't believed a 16 months old bike needed so much replacement..4 sets of tires, 3 sets of wheel bearing and right after this it need to change a top head gasket for oil leaks....i presumed a Harley is too delicate for me to trashed...maybe it need a time-off and i need another bike for my daily hard riding.......
