2016 FLTRXS, Road Glide Special. 103 6 speed.
Bike feels nice and healthy down low, but only from about 2600 up and in a gear that lets it wind up a little.
seems like 2600, 2700 to about 4500 tops, it picks up good steam kinda short shifting it a bit. It's stock besides SE Ventilator, Jackpot headpipe and slip Ons and dyno tune with Power vision. She's flat flat below 2600, and anything past 5000, it signs off too.
is that the characteristics of the stock cams?
I'd like to get a little more out of it. Nothing crazy. Just feels flat off the bottom and not much leeway on slight over rev either...

use the calculator there to enter your specifics you will see the compression results, use a cam that would be around the same compression or preferably higher ( corrected/ dynamic) but will gave you a bump in performance.

Andrews 57 is a good all around set of cams for the 103 inch motor. There are several cams that will improve the way the motor runs, just that the Andrews are not high dollar cams, so they help keep in a budget if that matters.
Below is the stock Rushmore and below that the 103 with Andrews 57's.
Yes, I did take a look at that. I'm about a 30 minute ride away from Fuel Moto as well...lol.
The 57H looked good, and possibly the 48H.
The CycleRama 570-2 was a pretty good looking cam as well. I believe they used a Dyna as the test mule.
How is that 57H in a heavier bike?

Not really apples to apples...Fuel Moto test was done with a 2>1, not a stock cat headpipe
The Jackpot head pipe I have is catless. 2 1 2.
I'm sure a decent 2 into 1 would make a little better all around power. Right now I'm stuck between the 48h, 57h or the CR 570-2
I do ride 2 up about 1/3 of the time. Im looking for something that starts to come on decent around maybe 2500, but carry to maybe 5000, or a little more.
The stock cams feel a little soft off the bottom, but also sign off kinda early too for me. Just when the bike is picking up good when you're on it hard, it goes flat too soon for me. The CR 570-2 looks like it may be the best choice. 57h carries a little more torque to the right.
48h, I'm not sure about, but doesn't look bad either
