So I'm a newbie to this forum. I have spent at least, a couple hours a day for the last 3 or 4 days, going through the forum and becoming a little more familiar with what goes on here. Its nice to have some where to check on things and see what works and what does not. I just wanted to go ahead and give a thanks to everyone here I've learned a lot already and can tell there is still a shit ton more to learn. Being a 20 year old Harley owner its nice to have people to verify the best set up with. So I guess I still have a couple questions that need answered. First off what does it mean to run "topless?" and secondly what are you guys using to tune your bikes with the SERT with out having to go to the dealer? Thanks again guys.
