Cam Question
Hi Everyone, Hope you all and your families had a super delux Christmas. I am new to the forum, but have been reading posts for quite a while. I'd appreciate any kind of help that you all could give me. Cams......cams, cams, cams. I know this is probably one of the most talked about topics around.
Here is my deal. I'm 59 and have been riding motorcycles since I was 15. I bought a new 2011 Road King Classic. I put a Big Sucker on it, Rhinehart True duals and had the bike dyno'd with my Screamin' Eagle Pro Super Tuner. My dyno results are 80.97 HP and 94.36 Max Torque. These are good numbers and I am very happy with them.
Almost all of my riding is 2 up with my wife. As usual, I'm looking for some more bottom end poop. I have researched cams to the point where I can go no further on my own. I have a great rapport with my dealer but would appreciate some input from you all.
I've got it narrowed down to 2 cams. The SE204's and the Wood's TW555......the triple nickle.
Warranty is not a problem. My dealer will be installing either one, has worked on the bike since I bought it and they said that they will honor any problem regardless of which cam I have installed.
Last, would you also give me some input as to EZ push rods versus solid push rods. Would SE 1.725 rockers be something that I should also consider doing?
I'm hoping to get this done in the next month. Thank you all so much for your response and help in this arena. I really appreciate your time in response to my questions.
Happy New Year to you all. Rock On!!!!!

I am going with andrews 48H cams for the same reason you are looking for upgrade. You took care of one big bottle neck by changing exhaust and intake. You should be able to drop in the cams without having to change the push rods at all. Look at Andrews specs before you buy into woods or SE smog cams. Just be an informed buyer. If your dealer is doing the work, they have access to drag specialties catolog and can buy install and warrent the work.

Can I offer an alternative suggestion? If you modify your gearing you can get a worthwhile improvement. Either compensator or front pulley can be changed from 32T to 30T, which will shorten gearing a little and give you almost 7% increased rear wheel torque. Any other improvements you make will be additional to that.

For What it's worth, I ran S&S 510C cams for over a year in my 96TC A motor and had very good results with the balance of the engine being stock with a Stage I upgrade. I ran the bike all over the NC and north GA mountains last summer and had plenty of bottom end thump for Deals Gap, too.
I've since went to the S&S 585C cams with my 103 build and am just as happy with those cams so far. BTW, the S&S 510's are going into a buddy's bike in January after 9K miles in mine and showing not signs of wear.
As far as adjustable pushrods go, I'm a believer! As you starting installing non-stock cams you need the adjustment to get into the sweet spot of the lifters and dial out any rocker ticking that may result from the build.

Sounds to me like you are talking about a "cam only" upgrade? The Woods 555 appears to be a good cam but (from recent dyno results)but, like most of the Woods cams, likes compression; say about 10.5:1. So, with an intake close at 41*, a cam only upgrade with no headwork and machining for compression, I would pass on the 555.
The SE204 is a very underrated cam and combined with the 1.725 rockers, you would see a nice gain with an intake close of 34*.
In your situation, I would take a hard look at the new Andrews 48. It was specifically designed for your application; a cam only upgrade in a bagger. The intake close at 29* is going to get your corrected and cranking compression up where you should see a decent gain. Do some homework and look at the 48 before you pull the trigger.

Thank you DJL for the supporting of the 48H Andrews cam. I thought I did my homework, and my wrench friend was steering me towards the Andrews 26. The 48H has higher lift, better scavenge and results are showing 90HP wit 106TQ with just stage 1 intake upgrade and true duals. Not much varience on the slip ons people are using.
Reagrding replacing lifters, not needed for this build, but to each his own. If I was constantly in the motor, yep, adjustables would be there, but I am doing 1 only build to serve one only purpose, get me,my wife and our gear up a hill or around a big truck with a twist of the throttle and a head snap. The 48H provides flat TQ and HP low to mid about 4800RPM before falling. That is well within the range I ride in. The OP would be well served with the 48H (IMHO)

This is a good example of how dyno numbers, by themselves, don't mean much. 87HP/106TQ from the SE255 looks a lot different on paper than the 90HP/106TQ from the 48. Compare torque under the curve and the 48 will have more and carry it further.
