I think I have read just about every post I can find on this board about cams. I have a 2008 SERK and I'm wanting to put a set of cams in the bike. I'm looking for as much low end torque as possible. i'm not trying to be the dyno king and chase after high HP numbers. I figure most of my riding is at low RPM's unless goofing around with friends here and there for an occasional race through the gears. I could care less about being the fastest. Looking for good low end stump pulling, 2nd gear spinning power. I have a V&H Pro Pipe and SE Heavy Breather and PCIIIUSB, other than that nothing is done to it. Also will I be ble to find a MAP for this application?

I'm going to bring the bike in soon for its 10K service any advice as to things I should ask them to look for? If so anything that can help with the cost of putting in the cams? Sorry for all the questions, this is all very new too me and there seems to be way to many cam choices out there. Thanks

u already have the best cam for low-end in it... u say u have a PCIII, does it have a download for what u have done? u should have the bike dynotuned correctly for the best performance...

Really? Is there anything else that you could recommend? Maybe get a little more compression out of it? If so how do most people do it?Yes it came supplied with the MAP already installed. The REv Limiter was supposed to be raised to 6200 but i don't think it was. My tach is acting up a little now, just noticed it on the 3 hour ride home from Laconia. I have only had the bike for a week.

The first and most important question is whether or not the head replacement has been done or is required for your VIN.

Not sure, I had the local dealer check the history and the only two things that ame up were:

3/26/09  Description: Touring Filter Shell

3/26/09  Description: 07/08 CVO 110 Gaskets

Well, if this is the Product Enhancement #0906 (which I would call the dealer tomorrow about) then it needs to have the heads replaced under warranty. If so, it would indeed be a good time to think about changing the cams.

The 1st item is a "safety recall" notification. It requires the fuel fill to be replaced. The dealer should have told you that this is something that should be attended to quicker rather than "when you get to it".

Was the bike purchased from a dealer?

Do a search on this forum for "shell" (you'll also get Sp'yder's comments about gas  ) and also "0906" to start you learning curve. Don't worry, you're in good company and you will enjoy your new ride!

Thank you!  I have a copy of the safety campaign history. It is 0906, it says completed but how can I be sure they changed the heads and not just replaced the gaskets?

[SERK3]

I don't think replacing the heads are included, The letter i have says Product Program 0906,O7 FLHRSE3,08 FLHRSE4  Models built before May 14, 2008 and 08 FLHTCUSE3 built April 9, 2008 hrough May 13, 2008, Upgrades include improved top end gaskets, center crankcase bolt and the ACR (automatic compression release)
I bought my 07 FLHRSE3 in Sept. 06 so it was one of the early built ones and have not had any problems (knock on wood) so i have not had the 0906 done as of now. We have until August 14, 2010.

[MUFFMAN]

Program 0905 for the Ultras included changing of the cylinder heads. I believe 0906 for the SERK's was gaskets only.

[grc]

Heads were included on the Electra Glides (CUSE), but not on the Road Kings (SERK).  We never did come to understand what that was all about, unless there was some strange theory at the MoCo that the lowers on the 'glides had caused the engine temps to be higher than on the rk's.   The reason for the head change was the new valve guides with the retaining clip that would prevent a poorly fit guide from dropping at high temps (which in fact happened on more than a few engines).  There are some other earlier threads that explain in more detail.

Thanks for all the replies, it seems as if for the SERK it was only gaskets not heads according to my local dealer.


Back to the CAM question. So from all of my reading if I want a little more power I should bump up the compression and then add the SE251 cams. The added compression will make up for the cam change down low? Is this correct?

[MUFFMAN]

Maybe AJ will chime in here. I believe he went with the 251's & high compression pistons & he is quite happy with the setup.

Actually I did go with the 251's, hence my interest in this thread. After discussions with my dealer about my riding style, I decided not to go with the high compression pistons. The 251's were plenty enough for what I wanted to accomplish, which was a little more low end torque. I can only confirm this by seat of my pants analysis as I have not had it tuned yet. I will say that I immediately noticed a change in sound. It was a lower rumble a little louder. Overall, for the cost of the cams at ~$300 it feel it was worth it. 

The 251 is a direct drop in cam. Others here have had great results with Woods cams. I guess it all depends on how much you are willing to spend and how much power you really want. I know of one member here that has probably spent upwards of $30k rebuilding his 110" engine with all non Harley parts. I personally want a bike that I can turn the key and ride with NO problems, for a long time.

Hope this helps,

AJ

I thought the 251's actually lost torque down low but you gain more power up top?  I'm curious to see your dyno chart once you get it tuned. Thanks

10-4 Be happy to post. Now all I have to do is find someone semi close or go see 2lane in Joplin, Mo.
