I always like seeing these so thought I'd post mine. I recently purchased the S&S Hot Set Up and swapped out the 640 cams for 585's and the 11:1 pistons for the 10.2:1 pistons. I wanted a cooler running engine good for passing on the freeway and fun for burning around town or on the highway. The shop had a lot of problems with S&S parts. They were either on back order or there were quality control issues. The engine was torn apart a few times due to faulty parts from S&S. After about 18 months I finally have a bike that meets my expectations going into this whole ordeal (still a bit more tuning to do for hot idle and start up idle). I was aiming for 125hp/140tq. I know it's not a rocket compared to others I have seen on here but it should hopefully be reliable. If I didn't have a balanced engine I think my numbers would have been closer to where I had wanted them.
