I'm familiar with the Feuling Reaper 574. I put a set in my 07 FLHX. I know the forum here recomends that same cam. I've been looking at the 594, but my concern is the .604 lift on the exhaust side for a bolt-in cam. Does anyone have some knowledge here or is the 594 just too new of a cam?

[TorqueInc]

neither of those cams with stock compression as a bolt in will work well in a 110.

I don't want to contradict the professionals, but I had the Fueling 574 with stock compression in a '12 FLHXSE, and it worked very well.  Then I installed 10.5:1 pistons, which Fueling recommended, and the difference wasn't even noticeable.  My dyno with the higher compression was in the same range as others here with the 574 and stock comp.  Money wasted, IMO.  Of course, I was planning to do headwork next year...  

There's a bunch of good cams that have been discussed here, and many owners are familiar with the Fueling 574.  Others that I believe will work just as well for the heavy touring bikes are the Genesis 577, Kuryakyn TC-24D, Woods 555 and 777.  I don't really know that you'll find much seat-of-the-pants difference.

FWIW, I'm probably not going to modify any of my bikes more than a pipe and fuel controller in the future.  The lifters, compensator, and crankshaft are weak links that don't seem to stand up well with even stock power.  More importantly, how often will you really need a lot more power?  With my bike that had more modifications, I would go WOT once or twice a month, just because I could.  With the new (so far) stock bike, I feel no pressing need to ever go above 5000 rpms.  Maybe I've just grown up a little?

Without re posting a tons of the sheets look at the other post on the 570 cam I have a few in there as well. Show an example of power to tq etc. but you get the idea , if you want me to post here i can as well .

  Would be highly dependant on the pipe and the tune as to what you would feel

    GMR's or Rolands cam thru Kury are a step in the right direction and offer big gains over other grinds that might look ok on paper and a dyno sheet but out in the real world.....not so much.

Can't speak for the other cams mentioned, but I bought my 2011 SESG with a V&H X-pipe already on it, and I put the bassani 4" mufflers with race baffles on it, but had done nothing else.  Fast-forward 2 years later, when I normally trade (while they're still worth something) and I didn't see anything I wanted badly enough to pull the trigger, so I figured I'd just enhance what I had.  Put the Woods 777 cam in, (stock pistons/compression) and the harley race-tuner.  Bike made 94 HP and 101 Tq before the cam (remember it already had the x-pipe) and made 107hp/114tq after the cam and race tuner.  So I can speak from experience with the 777 cam.  I consider it money well-spent.  Pulls harder from mid-range on up.

If you have the dyno sheet can you post it.. Peak numbers are great but that is not showing the entire story. I know what that cam does and where it does it at. Most are not happy with the power curve of that cam with out increasing the compression. Not that its a bad cam just that it is way more suited for higher compression that the stock engine has to offer.

[TorqueInc]

  Would also make a good bandaid for poor portwork

Fueling 574 cams on a 2012 Road glide ultra 103, would it be worth while to add the SE heads and 10.1 : 1 matching pistons with SE 58mm throttle body? I have the Fulsac dx pipe with 2" cores and SE ventilator AC.

[Unbalanced]

I'd save the money and send the heads out if you have the time to do so.  I chose to go with sending my throttlebody to S&S and use their 58 they turned it in 2 days.

going from stock compression to 10.5-1 (in the area that the 574 wants to be in) with no change in HP/TQ is very odd,the .574 should have been very soft before the compression increase

What is it yours lacks?
IME adding compression and airflow with this cam in a 103 they didn't scale as well as others with similar duration. It is an exhaust thing, not pipe as much as LC and duration of the cam. My advice ride it as-is or change cams and do head work. No piston change is needed either. It is a very simple and cost effective way to get to 115/115 with a strong torque curve and still retain the stock TB and injectors.
The CVO 110 motor same applies but the HP and torque numbers end up in the low 120s square

[Jbbrown73]

I have the Kuryakyn 24D in my 2012 CVORG with lifters, adjustable push rods and exhaust and it made a world of difference in the butt dyno. The valve train noise is almost non-existent and it runs super cool.

[Unbalanced]

JBBrown you have what I consider one of the best combinations that work for the 110.  They give up very little on the bottom end to, relieve the heat and have the potential to deliver decent numbers.

[Jbbrown73]

I think it's stronger on bottom than the 255, but it pulls like a beast all the way to 5k. I have to give mega kudos to Jason at C&S Speed Shop in metro St. Louis! The build and tune is fantastic. This is by far the best running bike I have owned. I'm taking my 2015 to him tomorrow to get the exact same treatment.
