I have the extended warranty and thought staying with OE would be good.

[prodrag1320]

no real difference,quality wise.but as for the best fit to your riding style, specific cams from each would have to be compaired

[GregKhougaz]

Welcome, Istojack,

Define, "good."   See here:  CVO 110 Andrews 54 dyno test! 120 LBS Torque! 102 HP!

There are many other choices....

OE is original equipment as supplied from the factory.  Any alteration after the fact (whether it be from Harley branded or others) is enough to allow the service contractor room to bitch if it chooses to.

The service contract doesn't differentiate between modifications using H-D branded parts and aftermarket branded parts.  I'd suggest you read all the fine print and exclusions in the contract you should have received.  As Twolanerider mentioned, OE is the stuff that came installed from the factory (Original Equipment).

As for the many choices for cams, it would take days to go over all the possible choices.  I'd suggest you first determine exactly what you want the results to be, and how much money you want to spend.  Are you looking for just a bolt-in cam change with no other modifications, or something a little more potent that requires compression changes and head work, prefer something reasonably quiet or don't care about valve train noise, etc.?  This can quickly become a very deep subject.

here is the stock 255 cams with a set of D & D Fatcats only. Cam comes on very early for every day riding. I have a Andrews on my other bike and though they definitely "stay longer", I prefer the HD 255's for my style and as you can see, with a good tune...

[North Georgia Hawg]

I run the 54H cams and really like them. They don't "come in" strong until about 2700 RPM tho... so they are definitely not low-end torque cams. However, they will stay in all the way to redline - unlike the stock SE 255s that are pretty much done by 4200 RPM or so.

I am considering a cam change though... the exhaust timing of the 54Hs may not be very compatible with the Drago's S/C/S-4 2-into-1 pipe I have on Buster now. I recently installed a Ness Big Sucker Stage 2 to replace the Ventilator... and the VTune runs show some significant dips at certain RPM/kPa cells that were NOT there with the Ventilator. Our theory is that there may be some complex gas flow dynamics going on in the S/C/S-4 pipe with the increased airflow that may be slowing down the flow through the collector at those RPM/kPa settings, and we suspect this may have something to do with the 54H cam valve timing and overlap. But that's just a guess at this point. I collected VTune data on two LONG runs of about an hour each on the highway, and filled up the the DataMaster histogram completely on both runs. When VTune showed me the data, there were some RED cells in these RPM/kPa ranges, and it made some BIG adjustments to the VE tables - most notably from 4500-5000 RPM and 50-80 kPa. Now admittedly that's really cranking the engine - but it showed MUCH lower VE table values in these cells in both cylinders than it did before I installed the Big Sucker Stage 2. That's got to be airflow...

The 54Hs are a great cam - but Andrews has just come out with the 57H cams... they are wide-lobed cams with slightly different valve timing, and a very different lobe profile that significantly increases the "dwell" according to the Andrews guy I talked to this week, keeping the cams near their maximum lift for much longer than the 54Hs do. This might - or might not - help my particular situation... but they are definitely worth looking into for a 110' engine, and Andrews will recommend them over the 54Hs for 103s and 110s, now that they are available. Of course, higher dwell means steeper ramps - which are harder on the valve train and will likely produce more valve train noise. 

I'm also looking at the TMan 555s (Torqster and regular), the TMan 590, and even the SE 259e cams... but the 57Hs are a lot less expensive, and I like to stay in the 230s duration. But maybe this big Drago's pipe needs more duration to perform best. Changing cams to suit a pipe is kind of backwards... but I LOVE the S/C/S-4 and I'm not giving it up... It's always something!

Waiting to read more about long term info on the 57H. Sounds like a good cam for my needs.

Yeah, I agree. Since it's so new, it will be awhile before we get real-world reports tho.

Andrews told me that it was really designed from the ground up for the 103s - but it performs great in the 110s. The duration and valve timing is only a few degrees different from the 54Hs - but that can be significant when the engine is running hard. But they said that the increased dwell is the really the big difference from the 54Hs.

THe 57 has been working very nice. Long term well have one customer with just about 5K on it. Customer has no issues makes good power. for just a bolt in.. But as we know that there is more than one cam that works well in the 110 engines.

After seeing Vanamal's awesome dyno chart, I'm looking at the Fueling 574s now... what do you think about those cams, GMR?

[CVOThunder]

I'd like to retain the low end torque but increase the top end to around 5200. Willing to lose a little bottom end as there has to be a trade off but not too much. The 54H is probably plenty for me since it's a quiet cam but when I get serious about doing this change then I'll look at making a spread sheet to compare cams in my range.

Maybe a good business would be Renta-Cam, moto, try it you may like it if not try another.
The cams mentioned here are of many different classes and need different combinations of parts (especially compression) to make them perform properly. As a bolt in on a stock motor a few of them would be big disappointments IMHO.

Rent-a-cam!!!!!!!!!
That is a good one.
If wanting the low end similar to the 255, but want it to carry, I'd lean in the direction of a Wood 6, set at 10.2 cr.
Cams, pushrods, gaskets, re-surface heads, tune, smile.

The andrews 57 is a bolt in cam and it works , with out changing up the engine other than cams it is what it is.. The engine is low compression to start with so all you can do is find a good match for those parts and go from there. The wes brown 575 works well as a bolt in also. I have not run the 574 in a 110 so I cannot give you any info on that.


But I am sure you can find some one to help you there.
