Looking at this cam set, from Zippers performance RS587.
I don't plan on doing a build, but looking at added performance.
Just wondering if anyone has used this set of cams.
Also thinking a Tuner like the TTS?
Red Shift Cams® RS587 for Twin Cam®
$399.95
4.88888888889 out of 5based on 9customer ratings (9 customer reviews)
This cam was designed and optimized to be the best bolt-in cam for the Harley-Davidson® CVO® engines. The RS587 cam dramatically increases power and torque across the entire RPM range. Unlike other cams, the RS587 was designed to work with the larger valves and heavier springs that the CVO engines are equipped with. The RS587’s specially designed cam lobe ramps ensure quiet operation of these heavier parts, while the lobe profiles take advantage of the high flow CVO heads to develop more power to red line.
The RS587 was specifically designed for VALVE TRAIN components AND LOW COMPRESSION in the CVO 103 AND 110 engines. No compromises were taken in this design to optimize these cams as the best bolt in design.
The RS587 revs freely and pulls to nearly 6,000 rpm for a true hot-rod feel. The difference is simply amazing for a bolt-in cam. This setup will produce approximately 200psi cranking compression in an unmodified CVO engine.
Although Zipper’s offers higher output options for the CVO® engine, the Red Shift RS587 is the best option for a bolt in cam with performance exhaust and EFI tuning without increasing compression or opening up the top end.

switch out your lifters while you're in there.
Definately add a tuner. Have you done exhaust? Seriously consider a full system to allow it to breath better.
With a tuner and properly tuned (not a downloaded map), you should see noticeable difference and much better temperatures.
As for the tuner, you should find a local dyno tuner discuss what he prefers to work with (TTS, Power Commander, etc.). Best to use the tuner they prefer to work with.
Suggest you discuss cam choice with the local tuner

I am replacing the lifters and cam bearings and asked the indy that I have known for about 20 years, about a cam up grade.
Told him I don't plan on doing any major upgrades to the motor, he suggested this cam set, he likes the Thundermax, I think it may be more than I need for, other than cams, a stock motor.
We travel and pull a Bushtec trailer, and was looking into a cleaner running motor, as I get soot on the cooler cover and fuel mileage in the mid/low 30's, no power problem with the motor stock.
This cam set reads in the description like a good choice.

Joel,
You have a very reputable builder/tuner 4 hrs from you. Don is excellent at what he does

Looks like a really good choice Joel. I've been a Zippers/RedShift fan for over 30 years. Only once did I cheat on them with another brand and ended up with a noisy valve train and a power band that wasn't where it should be.
Let us know how it turns out neighbor.

In my 2010 FLSTSE I have the Woods TW-7H and it works pretty well. My 2012 FLSTSE3 is stock with 7,500 miles on it. I'm highly considering the Red Shift 587. A lot of guys are saying good things about that cam.

Cams are not good or great, they are a good fit to reach a goal or not.
The RS587 was specifically designed for VALVE TRAIN components AND LOW COMPRESSION in the CVO 103
The stock 103 is different than those 8.3:1 103 engines plus has lighter valves and smaller valve sizes.
-
I'm probably stating the obvious, but what are your thoughts on this cam for Joel's application for his CVO with 110 Cu. In?
-
I am the wrong person to ask. I own a CVO 110 and I was happy with the SE255. I went with a fullsac combination of pipes and an Andrew 54. It is not cutting edge anything but I now have 100hp and 110tq and a pleasant ride that I know is easy on the valve train. No head work but I did change the springs to a dual spring, no dampers, with 155# seat pressure. About the same as stock pressure on the seat but 100# less spring rate. Changed the lifters to Morels and added rocker lockers. My bike needs to be ultra-reliable for the rare time I have during the summer to get it out. I am happy with it as-is.

I can tell you from personal experience running the 587 cams that if your at stock spec 110 ci the original 255s out perform them down low. I was very disappointed. But when I added 17 more cubic inches I got the low end grunt back but I think there are better cams for the 117. Im starting to think tman 625!
-
Yes the motor is still internally stock.
Low end torque is important to me being we pull a trailer on our trips.
When I do the lifters and cam bearings I'll confirm the condition of the loabs and go down the path they take me.
TTS as of 2 days ago is still unavailable, could that be do to new EPA regulations?
My indy said he can get the ThunderMax, seems like I'm still on the fence on this.
I keep remembering what the HD tech told me back in 03 when I took my first Harley in for the first oil change. " If you want the motor to last, leave it stock" Obviously he was paid by the hour, but I think he knew what he was talking about.
-
Keep those 255s in there on that stock 110 and spend the money on a tune. Its quick when short shifting in the power band.
-
Thundermax not. ;)
-
So if you're not a thundermax guy, what would you recommend doing with a stock 110?
If doing a dyno will there be a different map download to the ECM or something like the TTS installed?
And what do I do before I bring my bike in, upgrade the air filter and exhaust?
It seems to be a bit on the rich side, average is 35 mpg, exhaust is not uncomfortable hot on the legs.
Plugs changed last fall, and the OE were clean.

Keep the stock ECM and have Dead Center Cycles in Lacy tune the bike using a power vision license.
The stock ventilator filter is adequate. Exhaust, there are many. I run the Fullsac DX and stock mufflers recored with 2" baffles. Good sound and performance. As long as the cam remains stock exhaust is more of a style and sound pick. My CVO makes 100/110 and has all the grunt it did stock. Bottom end and heads are stock, just a cam change, lifters, and valve springs.
