Re: what did you do to your motor bike today?
Today I finished the seat suspension. The 1-3/8" tires were driving my spine into my skull. I removed the seat post clamp and greased the post. Then a car valve spring and a cad plated (OLD curtain rod) 5/16" dia. guide that loops around the top tube and turns 90 deg. with the ends anchored in partial notches milled into the seat frame clamps that secure the seat round support members. This keeps it from swiveling or coming out. It seems to work great. The spring is just right so it doesn't bottom out and still absorbs shock. Well worth doing and almost as good as a rear suspension. Now I need to consider making a front spring system that is stable.
