my buddy that owns a trans shop often replaces the plugs in the back of the block, depending on the shape of the vehicle, just in case....Jeff, relax a bit. The wheel weight is funny. Never purchased a tire warranty on a bike until i bought a replacement tire on the back of my Suzuki. First night riding home from work with the new tire, guess what I hit? Guess what it did? 3 days later, same stretch of road take a guess what I hit again? And what happened??
