Thanks for the welcome. I stumbled onto your newsgroup a few days ago. Already learned a bunch of useful things regarding noises, tires, exhausts, etc. Really appreciate it. Think I can add a few useful things, e.g. I have ridden many thousands of miles on both Mustang and Corbin seats. Will post my experiences with them soon. Thanks again for the welcome. It is good to be a part of such a knowledgable, enthusiastic, interactive group.
