So this is a metaphorical representation on part of the motorcycle in indicating your past problems, shown here as the "grime," are now over and being easily washed off. Then youll be free to shift into "high gear" and go forward.:clapper:
ran429, did you change the shifter shaft seal? If so, did you find that the new seal went in too easy. I've found this to be the case on a couple of 1200's I've worked, the seal was so loose on one that I had to use a sealer around the outside of the seal to keep it from leaking.
