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 !
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.
