I bit the bullet over the last 3 months and got the cams, lifters, oil pump and cam plate replaced with S&S components on my 2014 SERK. Also just had the new 110 high comp S&S pistons fitted. This goes with the Bassani pipe, TTS tuner, larger matched injectors and dyno tuned. The engine is now perfect, the last dyno run showing 112bhp and 118ft-lbs. Pulls like a train exactly where I want it and sounds great, without being obnoxious.
I know that the 2014 110 seems to be more robust, but I love the bike and intend to hang onto it for many years and wanted some long term confidence and reliability.
I would post the dyno graphs, but I seem to be unable to shrink the picture down to the allowable size to post. Will play around in the sand box and see if I can get it too work........
