Pulled the rune outta the garage today. rear tire looked low. it was. 5 lbs! found a phillips head screw in it. Guess i get to learn how to drop the rear wheel. has anyone done a step by step tech write up on how to drop the rear wheel? I got the service manual of course but a write up by one of us would be a big help. Also, any advice on tire replacement? stock 180 or the sport 200 or 210?
