So, I have a bug for new cams. I have 2012 FLSTC with an (almost) stock 103" engine. I've added the Stage 1 SE air filter kit and Rush slip-ons. I had the dealer flash the ECU after I added the air kit. I'm looking to upgrade the cams, and I think I have the wherewithal to do the job myself. I have a couple of questions and am hoping that someone may have done this job before. - I'm looking at S&S 583's for the replacements. I noticed that they have a version that has a built in compression release on the exhaust valve cam. The bike already has an automatic comp release built in, so I'm thinking that dropping an extra 90 bucks on those cams is a waste and not needed. Any thoughts on this? - I'll be pulling the exhaust, and it looks like I can pull the entire system off at once by disconnecting the 02 sensors, removing the bolts for the mufflers and cross-tube, and then removing the exhaust bolts at the head. I'm thinking that by leaving the mufflers in place that it might be pretty heavy, so as much as I'd like to leave the system intact if I can, it might be better to pull the slip-ons. Again, any insight would be appreciated. Also, do I need to pick up anything other than new exhaust gaskets before remounting the pipes? One video I saw showed what looked like an o-ring being cut away, but I can't find any reference for it in the manual I have. Any other insight into the job would be greatly appreciate. I watched the JP Cycle video that runs for about an hour, and that was excellent. I'll be doing new pushrods too. Thanks for taking the time to read this!
