Recently purchased the 18 CVO RG but can't find the current engine specs. I was told, at the HD dealership, that it comes with the stage 3 but can't find any information on it. I wanted to install the Woods 777 cams when I install my exhaust and air breather but I'm not sure if that'll work since the website says 107-114 engines. I'm looking for more low end torque rather than high end power.
Anyone have any information on that particular cam with the new CVOs?

The cam for the 2018 CVO RG is part number 25400273, and it DOES NOT match any of the SE cams in the catalog. In other words, it isn't one of the Stage XXX cams.
I found these specs for the cam elsewhere, I can't speak to their accuracy but this is what I found:
Valve Lift Duration Timing Centerline Lift @ TDC
Intake .438 188 -9 17 103 .050
Exhaust .432 212 48 -16 122 .041
Duration and timing @ .050" cam lift

Thank you. Would the Woods 777 be a worth while upgrade if I'm looking for more low end torque?

Are you concerned about your engine warranty?

Not really. I skipped the extended warranty purchase this time cause I knew I'd be installing more after market parts.

Oh boy. Might want to give some second thought to that decision.

Already ordered the Woods 22X cam. Installing the Basani full exhaust and Arlen ness air breather. I'm keeping all the stock parts just in case. My brother has an auto shop with a couple of motorcycle lifts. We do all the work ourselves.

He's not saying it b/c he thinks it's your first rodeo. Check the threads in this board (the M8 board) about sumping, and also the one about leaking piston jets. Several people are on their 2nd engine; some on their third; there's a report that one guy is on his 7th (yes, 7th) engine. You might just want to keep your warranty.

I understand why he said it. I've read some of his post and yes it's unfortunate he's ran into so many issues. I'm fully aware but yet I've still made the decision to do the work. I didn't ask the question about whether or not to keep the warranty, my question was about the motor and cams. I appreciate his suggestion but it wasn't necessary.

I just wanted to help a guy out not knowing for sure how familiar he might be with how many others have run into warranty claim issues with the M8. I’m not one to tell others how or what they should do with their new bikes. I share my experiences and others can use the info or not based on their own mechanical skills or the size of their bank account. Its only money and time.
That being said its really not about my experience alone. If you saw the # of PMs I’ve received from others regarding sumping vs warranty claims you would better understand that I was trying help. I was not trying to diminish your enthusiasm for the changes you want to make to your M8 engine. Just confirming your understanding of the known issues. Sounds like you’re going into your mods with eyes wide open, which is a good thing.
For the record, the Woods cams are great. I run the TW408-6 in my other bike. If I were upgrading a stage III/IV M8 cam and didn’t care about about warranty, I would definitely be installing the WM8-408 cam - ripping torque with terrific lift for high end hp on a strong breathing engine.
I sincerely wish you good luck and that your upgrades go exactly as planned.

I completely understand and I really do appreciate it. I am fully aware and a friend of mine works at my local dealership has had several issues with sumping on his CVO. Not going to lie, I am a little nervous about it but I'm still committed. I apologize if I seemed to be dismissive of your advice. Thank you
Does the 408 require the spring replacements?

Yes, you would need either SE valve springs or the Woods BW-4V springs. Check with Bob at Woods cams. Let us know how the build turns out.

Glad to hear you're aware of the issue. We've seen people burned on warranty and ESP who didn't know how joyfully the "protection" could get voided.
