Cam Recommendations?

So I saw the post below this and live in Georgia and I went to my wife and was like I need 5K to give to Star Racing and make the Harley fast like the Ninja. Her response was not fit for repetition but needless to say I think I am just doing cams. When I talked to the mechanic, he was suggesting the 543's but I was like more power?!? What about the 574's? He said he had to take 574's out of his customers bikes cause they were complaining about riding in the parking lot... lugging the engine I think. I want the cams for spirited rides on curvy roads.

I have a 2011 FLTRX 103" with a K&N Heavy Breather and V&H 2-1 H.O. Pro Pipe and an ole timey fuel pak that never has had a good tune in it IMHO.

I am not an expert and would like to get feedback from you all...

Call Frank @dragos bike works. You have already got a good exhaust system on there, add a cam designed for the riding style you're wanting to achieve.

Don't guess, talk to a professional Harley Davidson motor designer.

Ask Frank to recommend a tuner in your area. If you use one of his cams he may already have a Dyno tune built for your application.

Why is that no body uses woods tw6-6 cam? I had them in 08 dyna 96" ported and polished the heads also tuned by Bean @ Big Boyz it absolutely Ripped and ran real nice.100hp/100ft lbs tourqe!
i got a set of 6-6 cams in a 95 twin cam. they are great cams. my absolute favorite one of Bob's cams is the 408-6 but you need a lot of cubic inches for that one.

HERE ARE 2 CAMS FOR THAT 103


Cam Specs & Overview
Recommended applications for S&S Cams:

HP103: For the rider who really wants the most top end horsepower. Easily make 100 horses from a stock engine with S&S intake and exhaust. Ideal for lighter bikes and racing applications where getting the most horsepower from a stock engine is imperative.

MR103: These bolt in-cams are for the rider who wants more of everything without giving up low end torque for high rpm horsepower, or vice versa. More power all across the wide power band, from idle to red line.

I just finished installing Andrews 48H in my 2012. I haven't had it tuned yet but with the base map for my setup that fuel moto sent in the power vision, I have to say the difference is big. I can feel the power difference for sure. Once I get it to the tuner to get rid of some throttle lag it should be great. Very plug and play.

The first thing that you're doing wrong is thinking that these bike can go fast, these bikes are touring bikes and go fast like a crotch rocket isn't their thing.
These bikes run better with a good low end/mid range torque cam, I used the Woods TW 222 and was very happy with the results but any cam that gives the bike good low end torque will be a good choice. Forget about HP numbers because HP isn't as important as torque and these heavy touring bikes need torque.

If you can get one that is good for both, why only focus on one and not a combination of both?

Yes, these are not "Crotch Rocket Fast" but seeing some of the builds I have, 120+HP and 130+ Trq is not too shabby for any bike...............its the 700+ lbs that wraps around it where it gets killed in performance - HD does not have the RPMs for HP but that is no reason to overlook it and a nice combo of both makes for some fun riding

That dyno sheet is from my friends shop down the street from me. They are great guys and are the mechanics that will do any work on my bike if i don't do it. Those are some nice numbers and just makes it harder for me to make a decision.:frown:

Andrews 48's, cam only, no head gasket swap, smacks big torque down low, and usually, is all in by 36-3700 rpms.
Expect 112 ft/bs +/-, and low-mid 90's hp.
Last one we installed recently with V&H power duals, and a good air filter set-up, tuned off at 92/114, and had recorded 116 ft/lb on one run, but we could not replicate that number.
BTW, for those that do not know, per Andrews, those are the non-emmission version of the HD 255, with a slight twist.

My motor is similar to mastergunner's. It's a 96 with V&H power duals, V&H high outputs, SE heavy breather, and a SERT. Due to the previous owner being stupid and over revving it we had the shave the heads .030...so now it's a 10:1 motor. I bought it with the blown motor so I was more worried with "will it run" than changing the cams, so the stock cams remain. It does have MCR's, which help.

What cam would you choose for this setup? I'm wanting mostly low to midrange power, 100 ft lbs would be nice. I do ride two up a fair amount.
I've considered the 48, 26, 37, or the 204. Would you pick one of these or is there something else you have in mind given the additional compression?

I've been here for a while and have yet to post, doing so now. I've been looking at all the options for my '16 FLTRU. I am leaning towards just doing cams, lifters and pushrods. Not sure I want to tap into all the head work and so on. I just want to pep up that 103 some more.
