110" Street kit with more compression.
Hey all, I have the opportunity to purchase an in stock 110" drop-in street kit for my 2014 Street Glide Special at just about cost.
The kit is #92500031, and I currently have Andrews 57h cams, S&S adjustable push rods, Race Tuner Pro, V&H Dresser Duals with 4" Rinehart Cans and a Big Sucker intake.
I want just a bit more compression out of the kit so I am thinking of getting the SE 10:5:1 pistons, part number 22502-07. The catalog sates these pistons work with 110 CVO heads.
I know it is mostly a bolt on kit, but I intend to do it myself and since the CAM is already done I am about half way there. I would assume this has been done in the past, was just looking for validation on my piston choice.
I know this won’t be the most powerful or free flowing as ported heads. I know the tire shredder kit will out do my plan, but the price is right and I feel I will get some respectable gains.

On my 2013 FLHX I'm running the 110" jugs/piston BB kit and had my stock 103" heads done and ended up with 85cc chambers. Using a .030 HG I theoretically wound up with 10.51:1 with 57H cams (pistons were .010 in the bore). Corrected that should be around 9.76:1 with the cams. I haven't checked for real what it came in at, I've tuned it myself. I don't know what numbers it's putting down, but the other day I walked away from my friend on his 2013 CVO road king, well past burying the needle at 120. It has plenty of power for me, I'll probably never dyno it as I don't see the need.
For the kit you're looking at with the CVO heads, I'd certainly do a .030 HG to get the compression up from the 9.3:1 they advertise with that package. Those CVO chambers are pretty big, around 95cc I think and the HG it comes with is .052. Going .030 HG you'll still only be running 9.67:1 static.
The engine builders can feel free to correct me, I'm just a hack that does my own work but I think these numbers are close for what you'll see.
