    I don't know anyone with the S&S 124 kit, but it sounds like it'll be badass! The nice thing about the kit is, it comes with a new oil pump and cam plate. FYI, the M8 CVO (bigger displacement motor) has had 5-6 different oil pump revisions which IMO is indicative of an oiling problem. My brother owns a 2017 CVO SG and he had his motor built to a 117 at the dealership and 250 miles later, the motor was starved of oil. I was riding behind him at 70+ MPH, when I heard a loud bang which sounded like a shotgun and I suddenly smelled oil. I thought he had blown his motor. Long story short, he towed the bike to the dealer and the dealer discovered that the motor was starved of oil, thus resulting in a damaged motor (crank, casings cylinders, oil pump, pistons, etc.). The crank counterbalance even disintegrated and sucked plastic pieces into the oil pump and casings. I think S&S is a solid company and I'm sure they have addressed any apparent oiling issues with the M8. I'm running their 475C cam and tappet cuffs in my 2018 SGS btw and the bike really gets out of its own way now.

    I like the way you're thinking! Have you heard any information on how well the 124 will hold up to touring? It might be fine, but that's getting up there in cubes. A couple of guys on here have had trouble out of their 120 motors. Hulkss ended up destroking his to a 113 ci (I believe).

    If your looking to get head work done check out JC Walker JWPerf.com. Look him up and give him a call he will do anything you want to heads and will steer you in the right direction. Had him build a set of heads for me last winter and oh how happy I am now.

    Now that's what I'm talking about! Please make a thread with plenty of pics of your head porting project. Will you also be installing bigger valves? Are you hand porting or using a CNC machine?
