I’d be interested in thoughts on the topic. I picked up my first Harley and it is a Freewheeler 2017. I’ve heard a lot of talk about the stages and just learning about them. I did exhaust, air cleaner and jetting in my last ride which was a 1999 Kawasaki Vulcan Classic. It did run a lot better and stronger, but the 107 on thisbtrike seems like a pretty good puller as is.
Looking for advice please.
