Hello
New to the forum. I have just bought a 2019 CVO roadglide.  I am considering a stage 4 upgrade but starting to do research.  Wanted to buy now since will be under the full warranty.

 But it looks like for example the cylinder heads are already the same size. I’m wondering if there is redundancy in the kit if it is even worth it. Pistons and cam look different (and I’m sure more).

I’ve also looked for some data on the increases. I see the 114 to 117 but nothing re stage 4 to 117.

I would appreciate thoughts and recommendations.

Thanks !

Depending how you ride stage3 for most is a better upgrade from a usability and fun factor standpoint (more torque where most ride)

If you always ride WFO the stage 4 is prolly a good choice

Compare the graphs

I haven't taken the time yet to look up exactly what the 2019 CVO 117 engine comes with, but I'm going to guess it doesn't come with the same heads, valves, pistons, throttle body, and cams that come in the Stage IV kit.  If Harley actually did install the CNC heads, 64mm TB, 11:1 forged pistons, and 585 cam in their production engine, it would be the first time they've done something like that in all the years I've been following them.

The attachment is from the 2018 SE catalog, detailing the parts in the kit.  I haven't seen anything different for 2019, but then again I haven't really looked all that hard.  As best I can tell, the only part of the kit that you already have is the cylinders.

Thanks so much for this.  I can’t find any graphs yet on the 2019 so that is a bit what I’m wondering about - that said, using the 2018 as a proxy is a great idea.

The 2019 motors are all blacked out on the mako road glide so also not sure I want to swap out the heads etc. As will clearly change the look.

Check out this video -


https://www.harley-davidson.com/store/milwaukee-eight-engine-stage-iv-kit - about half way through is where you will want to pay attention to the guy speaking,   he explains where the power comes in at.  Just food for thought.

first had the stage 3 on my 17 CVO Streetglide then upgraded to stage 4. Night and day difference to me but I do ride pretty hard. A couple of buddies of mine were asking me and have ridden with them both I tried to talk one of them out of it and one of them into it. One of them was complaining that he had to get a rear tire at 12000 miles, I told him not to get it.
Bad news on my story that many here know is both the stage 3 and the stage 4 sumped on me. Just full disclosure though they (Moco) is swearing they have fixed that. We will see--

I have a 2019 Road Glide CVO and installed the stage 4. Don't do it. It stutters pops and stalls when trying to takeoff. HD of San Diego installed the kit. They cant get the bike to run. Put the Screamin Eagle tuner on and said "they are out of tune". They want me to get a Power Vision. The whole point of getting the stage 4 was to keep the warranty. Now the bike runs like $hit...

I'm going to guess they screwed something up during the kit installation, either don't know what they did wrong or do know but don't want to go back in and fix it (they don't get paid twice to do one job), and the scary part is they are advising you to do something that will instantly void your factory warranty.  You need to go over some heads and not accept the BS response you've been given.

interesting it was done at San Diego as my 19 Roadglide is sitting at Biggs Harley down the street waiting for CARB (CA) to approve the stage 4. I was there today and dealer trying to talk me into taking bike and bringing back when approved and I don't want to do that. I have been a very good customer of this dealer for years and truly do like them and think they trust me but by not taking delivery I am obviously holding them up so hard to believe a dealer 20 miles away would take that risk by installing stage 4. Maybe they are trying to do something else and not use correct set up?

Now I'm being told there is a sumping issue. I don't see how HD would put a kit out that wasn't perfected...

As I posted on another thread this really makes no sense. Stage 4 as of last Friday has not been released by CA for compliance yet on a model year 19 which means SD would not be able to download the correct map for the Harley tuner which is the only way to keep your warranty in tact.if they tried to “jimmy” a different program to work it would not only explain why your bike wasn’t running correctly but would leave major warranty issues unless SD is prepared to flat out lie to the MoCo about work they performed. I have not heard of a 19 with updated motor parts and correctly installed stage 4 in any of the other 49 states sumping yet. A year ago we would see this combo on this forum almost every night. Unfortunately 3 of those stories were mine so been following the progress of the 19’s closely. We did see a couple when 19’s were first released but both turned out to have 18 oil pumps (yea, insane that MoCo would deliver them that way..).

They've put out lots of stuff over the years that isn't "perfected".  And that 117 Stage IV kit has been out for over two years now, so it's not like it's new.  But truth be told, the real issue has never been the kit, but rather the oiling system of the stock engine.  If you are experiencing sumping, Harley claims the change they made to the oil pump housing/cover seal for 2019 solves that problem.  Since you have a 2019 model, I'd suggest you ask the dealership to verify your bike came with the correct parts.  Other 2019's have been reported to have the older model parts installed from the factory.  They obviously haven't "perfected" their system for assuring the correct parts are installed when they build engines.

I'm still wondering about your dealership by the way.  The kit had not received approval from CARB for 2019 models and therefore was not legal at the time they installed it, then they had no clue when they encountered problems, then they encouraged you to use an illegal tuning device which would have voided your factory warranty.  In the future you might want to look around for a better dealership.

Under no circumstances would I let them install a PowerVision and void your warranty.  As has been suggested, the dealership has screwed something up and is trying to correct/cover it up with the tuner...that they'll expect you to pay for, along with the labor to install it.

You should hold their feet to the fire and ask the Service Mgr to explain how they intend to keep your warranty intact with a device, that when installed, immediate voids it.  If you get an explanation, you're going to need that in writing.

 

[JCZ]

San Diego HD will most likely tell him that "they" will warranty it.  But that's BS if he's on the road on a long distance ride and the bike has to go in to the closest shop for what ever. 

I agree with the posts above, they screwed something up and either don't know what they screwed up or don't want to accept responsibility for it. 

By the way.....I got a text from the pool boy an hour ago.  He said that the MoCo called him and stated that CARB has now approved the stage 4.  Let's see if the dealerships get a bulletin tomorrow.

I have a 2018 street glide cvo with stage 4 and an Ultra limited cvo with a stage 2 power cam. Do yourself a favor and just get a power cam. The 117 with a cam install only will wake right up.
 My stage 4 has a stumbling issue off the line.
My stage 2 limited is flawless and powerful. Yanks the wheel when I power shift.
