HD 117" KIt for 2015 CVO

From all the information I had read prior to installing this kit I knew I would have a dip in torque with the SE259e cams that came with the kit. I had really thought about getting the SE585 cams to have installed instead but I figured I would give the SE259e's a chance and see how they did.

I'll be the first one to say I am not an expert on cam selection. I also know nothing about tuning an EFI engine. According to the dealer I need more back pressure to get the dip out of my torque curve.

I have V&H Power Duals head pipes and Khrome Werks mufflers. Of course I was told a 2:1 exhaust would be better but I am a duals guy. My understanding is that the SE259e works better if I increase the compression ratio from the 9.9:1 that comes in the kit to 10.5-8:1 and that will wake this up.

I also know I'm being handicapped having to use the SESPT but I want to get a year on this engine work and then I'll cancel my ESP.

So here is my dyno sheet. Rip away...………

So a few looks but no replies.

I am trying to read and understand what is happening here. I know my FIRST major issue is the SESPT. Is this what is causing the dip in torque?

Or is it the V&H Power Duals? Or the Khrome Werks mufflers?

Do I need to be seriously concerned with the dip? Will the auto tuner help smooth that dip out as I ride it more? I know if I want to get the most I can out of this kit I'll need to go to an aftermarket tuner and I am looking into that.

Have you road it yet? Can you feel the dip? Ride the snot out of it and see what happens.
I found a sheet GMR did in a 113 with that cam and a fatcat. Table top flat. However, I do not know what compression it was running. He did say he was surprised by the cam in that build, not the norm.
Going to come down to what you want. If you like it how it is ride it. Would a 2-1 pipe void the warranty? If not, and you want to get one, do it. It won't hurt your build now or if you change it up later.

When you go with dealer kits sometimes this happens unfortunately. But you have a warranty.

Not my bike so I wont comment on what I would do.

2009 Road Glide. 16 in Vindikta Wild Cats. Aquatic AV, Stinger 700X4 to MMatts, Audiopipe horns.

Yes I've rode it about 150 miles so far but it was raining so I really didn't feel safe trying to ROMP on it too much.

Here is what I can tell you so far. Below 2500 RPM it isn't that impressive but it's got more grunt than the stock 110". Once it hits 2500 RPM's man this thing is a freight train. It'll go from 50-80 MPH in 5th gear in a blink of an eye. I like the way it sounds and runs other than I would like a little more down around 2000 RPM. The SE259e from all I have read isn't known for being a great cam down low unless the compression is bumped up.

That is why the plan is to have HD Performance work the stock CVO heads and cut the jugs to raise the compression up around 10.5-8:1. Right now the thing I need to decide is do I wait until next year to do this or yank it apart this winter and have it done so I can install the parts come spring.

Once I get some more miles on it I'll be able to answer that question more. I like the way it rides so far but 150 miles really isn't a good enough time to have a good feel for it IMHO. I don't want to void my ESP just yet and that is also part of what is holding me back from doing anymore engine work.

What compression is it at now? In a year are you better off running a different cam or increasing the compression? Lots to consider. How much will a different pipe help? All things HD performance can answer

Compression is 9.9:1 with the kit.

HD Performance is recommending the compression bump and keep the SE259e cams. He was okay with the pipes on it but wasn't sure about the mufflers when I spoke with him.

To be honest I don't know why I am worried about the ESP becasue on my last bike I put Woods cams & Power Vision on it within the first year I owned it.

Yes I should have gotten the thinner head gaskets and had them install them but forgot about it.

My main concern is that dip in the torque curve. I really wish there was an independent shop close by that I could go talk with. On my next trip over to the westside I'm going to find one I can go in and talk with them.

My .02......any Stage 4 Needs a good 2:1 and better AC than the Stock.......again, just my opinion here and many are smarter than I - The Street Tuner is not the issue, its a few things like the low Compression and CAM Choice - But, don't get caught up in the Graph and Numbers as that is a fucked up and costly rabbit hole to go down - Also, sadly, some of it will come down to the Tech who did the tune but same bike on a Diff Dyno with diff weather outside could produce a whole diff chart - Ride the shit outta it and have fun man....its the Butt Dyno that counts and the smiles per dollar ratio that I personally go off
Wildman and fitscott like this.

Nothing wrong with the 259E cam. I've seen plenty of dyno sheets with great curves and great numbers. Yes there are better cams out there but I had this cam in my 120ST and a friend of mine put the full 117" Race kit in his street glide with a D&D Boarzilla exhaust. My dyno was 125hp/132tq his 117" dyno'd at 123hp/130tq. I'll have to dig up the sheet but I don't remember it having any dip but if it did it was not noticeable when riding. I could smoke the back tire with it or I could easily pull the front end off the ground in 1st, 2nd, and 3rd. I would like to see the AFR line from your dyno pull. I'm betting that your bike could benefit from a more experienced tuner doing the work but that is purely a guess. If you have the current Street Tuner it is holding it back somewhat and would benefit from a TTS, TMax, or PV. Me and my friend tuned our bikes with the old SE Race Tuner which was basically a TTS tuner. I still believe your lines could be better with your current tuner. I would raise the compression just a bit as the pistons do sit too deep in the jugs.
