Really? Later 103ci engines have cam similar to SE-255? Always thought CVOs have 255 as stock cams. As far as I understood from diagrams 255 should be much more lower range TQ than stock cam. Since I'm planning to install SE-255 or 204 and I've just started my homeworks on cam I'd really appreciate further info.
Interesting...that doesn't quite go along with what Firefighter0763 is stating in his thread:

Guys, I'm wrong in my previous claim about the SE 255's. Not that it matters but I did read ( or misread ) it somewhere and can't locate the source of my mistake now. I have, however found evidence that the 255 indeed gives more low RPM torque than stock, ie: http://www.bigboyzcycles.com/tccams.htm
In the process, I may have solved my dilemma by looking into your alternative SE 204 Nostradamus74. IF I am correct this time the 204's rated RPM range is somewhat higher than the Andrews 57H's but otherwise is what I'm looking for and the 204 won't cost me my warranty.
S&S MR103 cam put good numbers on cdonis Breakout, glad you shared the info on those cams. A lot of folks been wondering about them. I wonder how the HP103's would dyno. You really got me thinking cams again cdonis, I've seen others spend and do a lot more for little or no more than what you got in return.

Maybe pick up a couple peak HP but lose a couple TQ and move it to the right as you said, that's what they tell with their chart. Cam shopping can be mind numbing somewhat. But its obvious that MR103 did what its claimed to do. Really got my heart on SE204's or SE211's .... they just got a great lope to them I like. Won't quite give the numbers you got but still great SE cam's. I don't know...this whole cam stuff drives me nuts.

They're "bolt-in" cams, so can just be installed without changing anything else from stock and work fine but I always prefer to stay on the safe side.
So analizing pushrods, bearings, clutch spring, etc...

Hey guys, been a while since I've been in here and trying to catch up. Those 10° riser/spacer things from amazon, does anyone have pics showing them with the stock drag bar? The only pic I saw was with cvo bars unless I missed something.
I have some 1.5" spacers now and want just a bit more, and those might do the trick if they can just be added into the mix with my current spacers. I was going to just get 2" spacers made but spacer jim seems to be gone.
Also, those of you that did the 1" or 2" lowering kits how much clearance did you lose in the corners? Was it noticable? I already have the peg feelers removed and still scrape pegs a bit in some corners.

Many of us have the warranty issue pending if installing non oem parts, that's why I'll probably pull the trigger too on SE-204 which are considered "middle range TQ" bolt-in cams. They should decently improve responsiveness at low rpms, getting better on middle rpms and reaching peak HP at 5800rpms. Low/middle rpms is the range where I detect a performance hole on the 103ci engine and is the range used 90% of riding time usually. Anyway I'll keep on doing my homeworks, mostly now studying which other parts should be changed if installing these cams.

I'll change out rods (the EZ install kit) and maybe tappets too; essentially anything the Dealer tech would like to work with that helps ensure best results and that $ave$ him time
. As I'd be preserving my warranty and not, therefore redeeming my EW, I'm figuring ensuing problems with anything else ought to be on HD's dime. Hopefully thats not a "Danger Will Robinson" idea. I've had a few like that .

Have you by any chance run across data showing the RPM band width estimates for the SE 204 and SE 211 cams? Andrews has these kind of numbers for their cams but I haven't yet found anything comparable for SE cams. I expect the 204 is a better choice than the 211 but it would be nice to see the data consolidated into a bandwidth comparison.

You won't see the 211's on the HD website but they are in the Screamin' Eagle Catalog. They say they work well with the 103, not much different than the 204's .... its just that the TQ curve is a little more to the right.

You probably know this chart that's available thru HD website. But it only covers SE204, 255, 254E and 259E vs. stock. Doesn't say anything about 211s (not sure they are not discontinued).
I'm pulling the trigger on the SE 204's. My Quixotic search for the "one true cam" is bordering on obsession. The voices in my head are telling me "buy the god damned SE 204". They've apparently had enough
