After reading everything about Amsoil Synthetic oil making their bikes quieter, smoother, easier shifting......... I decide to give it a try, and see for myself. The lifter noise is just as bad as before, if not worse. The shifting might be a tad better, and it seems like neutral is a little easier to find. Maybe I was just expecting to much, but so far, not overly impressed. We are leaving for a 3 day trip on the bike this Sunday, so that will be a good test.
