[?] Does anyone know how to get a little bit more out of a 1989 trail 488. I was told to put a few studs in it and then put a red spring, a 40/36 helix,a size larger wieghts and a black secondary spring. Anything else to do to get a little more out of it or does anyone know of a good or better setup than that? Ps: I'm already jetting down.
