This spring I purchased a 2003 FLHRSEI2 from a buddy (16,500 mi) but I can't find any technical info concerning the engine - I've purchased the manual as well as the supplement manual for the SE - neither tells me anything what I want to know such as valve sizes, cam specs, pistons, compression, etc - since it has low miles currently I'm not inclined to open it up just yet but at some point I'm sure I'd like to put in a diff set of cams at the least.  About the only thing I think I've seen is its basically a stoked 96".  Along w/ my '85 FXRS & wife's '88 FXR, I've got a 2000 FLHRCI (48,000 mi) but @ 30,000 mi did a 95" BB, flowed heads w/ 1.9" intake & 1.57" exhaust valves, Andrews 21N cams & hydro tensioner kit, 1.725 rockers & PC III usb, 50 amp Cycle Electric charging system - also lowered Progressive 440's rear, monotube fork cartridges & Prog chassis link stabilizer, Ness Big Sucker & Rinehart True Duals  - which I also want to add to this '03 except put on the new Prog 944's.  I haven't seen anybody (Andrews etc) have any cams specific for this engine.  I'd put in a set of the Andrews 21N's but I'm pretty sure they won't work - I love the low end TQ (dyno'd @ 99.91 TQ & 80.6 HP).  I think I probably have more TQ on my '00 w the 95" - it just feels like I have more but the '03 does seem faster.  The '03 has some true duals w BS V&H's straight cut slip-ons, PC III usb & SE air cleaner kit (assuming that wasn't factory).
I've searched as many web pages as I can find but see nothing that I'm looking for - everything 103 comes up for the newer 103's but not this SE 103.
Any help/info or web addresses is much appreciated!!!

Jerry, thanks for the info! - I'm curious, how/where did you get this info?  I haven't been able to get any info anywhere which is why I got onto this forum - I know the MoCo is pretty tight lipped but I just cant believe the lack of info on these bikes on the web. 
thanks again,
Paul

I guess I'm asking where did you come up with it being a SE-253?

Looked up the part numbers in a parts catalog, plus I have a 2005 version of the same engine.  Nothing changed from 2003 to 2005 in the mechanical stuff.  You can find the specs for the SE253 cams in a Screamin' Eagle catalog.  Harley never makes it easy and simple to find all the info you want, it usually takes a little extra work.  I guess I'm just one of those with a curious nature (that can be taken in more than one way, btw).

good info - I wasn't aware that those engine were the same but makes sense - I guess I had a brain malfunction - didn't even think about the glides but knew they didn't make the 103 SERK other than in '03 before going to the 110" in '07

have you changed your cams? if so, what'd you stick in as well as did you do chain or gear?

Is the same engine in the 2005 CVO Fatboy?
