I have an 08 Ultra with 23k miles on it. A friend told me that they will handle better if when you service the forks you put the springs in the oppisite way. He says the way the coils are wound they work better inverted. Anyone ever heard of such a thing?
No. Go by the recommended service schedule in your Owner's Manual unless the fork is leaking past the dust seal. Follow the procedures in your HD Factory Service manual covering your model and year.
