Hello  I am going to cam my 2011 Ultra Classic Limited 103.  Originaly I decided to use the SE255's, I'm going for the low end torqe and don't exceed 5000 rpm.  Than I read the S&S 551CE easy starts where similar.  I would like to know if there are any benefits and are they a quiet running cams.  I want to feel an improvement from when I let the clutch out, so I'm open to suggestions.  Thanks

 The Woods 222 would be a choice to meet your objectives.

 I'd give either Scott @ Hillside Cycles or Jamie @ Fuel Moto a call as they can give you all the information you'll need to make a sound investment, plus they sell the entire Woods line.

 An Andrews 57 is also a good choice and a few guys here are now running it with good results.

Good luck with your decision!

There is no other cam on the market that delivers the low end tq like the 255 does....NONE....! The downfall to the 255 is it dies quickly at 3800 to 4000 rpm and it has a little heat issue due to the high cylinder pressure it makes at the lower rpm's
Some cam Manufactures will say they have the cam like the 255 but in reality they do not.

What Doc said!!! I still miss my 255's although stage iv is very fun too. But I didn't go half way, from 255's to 259E's i gained 25 hp but only 2tq... The 255's pull hard down low, less down shifting and much easier do ride. Also 255's are everywhere...

If you don't already have compression releases, you will need to also factor in adding them if you go with the 255's.

I have installed a few sets of the 551's and they have always out produced the 255's at peak power but Doc is right, the 255 is king of low end torque.
This is a sheet of a 2009 Street Glide 96 inch motor, the before was stage 1 stock head pipes with rush slip-on/s and the after was the addition of the 551's and a tune. I have yet to install one that didn't do over 100 torque in a 96. They are a much more lopey cam than the 255.

we use alot of the .551`s,with mild headwork they`ll make power beond 4500 & dont seem to have the heat problem the 255`s have

It sounds like the 255's are for me.  This is a great forum, good information from seasoned professionals.  thanks All.

I use my '10 Limited (103) as my truck. I take the long rides, 2-up, pulling a 450lb trailer sometimes.
I've pulled this trailer all over the US, across the mountains, deserts, etc. I have the pulling power and passing power when I need it.
 As you can see I'm all about the torque in the lower RPM's.
I used a Andrews 54, little more compression, cleaned up the heads/valves a little, TTS tune, lower gearing and the usual mufflers, intake, etc.
It gets me to the 100/100 club
I have what I want to get the job done. VERY happy with the "package" I purchased.

How much compression do you need with 54's.

Mike

10-10.5 seems to work just fine.
not so much the compression in the stock (96-103) heads, more of the squish.
Just what I've noticed on a few bikes here. (Thanks, Steve!)

The Andrews 48 is the non-emission version of the 255, school-bus cam.

I did some reading on the Andrews 48, looks to have more overlap and runs out longer.  This looks like a better bolt on.

The 255's in a 103 is a great baggers cam. The low-end Torque to make riding a heavy bike responsive and the mid-range to make you smile. It's true that the power starts falling off over 4K RPM, but you will use that low end torque every time you take off and go through the gears. You will use that upper RPM HP only every once in a while. You cannot have it both ways without spending a lot of money.

Don't under rate the 255, Listen to what doc is saying

Thanks for the advise, I can sometimes do too much reading.  Back on track for 255's.
