dang man.. I just tossed 2 brand new sets of stock lifters thinking no one would want them

there are tons of 255 cam sets on eBay that go pretty cheap plus a lot of guys pull them from the CVO models in favor of other cams. Might want to check on that "other" forum for some. Part # should be 25638-07

Here's one and here is the tappets he mentions in the description

just for the record.. not saying anything about your tune because it sounds like you got a bad rap with this tuner...

Unless your bike is being tuned completely in open loop, the AFR/Lambda will be set to a certain criteria and then when the tune is done, the closed loop range will be set back to factory settings. This keeps the cruising range in closed loop mode whilst allowing the non-cruising ranges to run in open loop. Your ECM compensates for the changes in closed loop areas, whereas the open loop areas, your ECM can't compensate there.

Default was in open loop

was done in open loop just a basic afr right from se tables. I asked about why it was at normal numbers right off se tuner map and got thats just how we do it. fast and dirty is my guess not a real dyno tune
talking to another tuner after I questioned this and he said he sets it where it makes the best power may be lower or near the 14.6 depending on where it runs best for that rpm range, guess thats why it takes so long for a real tune, dial in all the rpm and throttle ranges,.
the second tuner said he wouldnt touch the bike with the ccp up in the 208 range since there wouldnt be much magic he could work in that range of the 255 cam which is pretty well where it lands with stock 85 cc heads and -1.5 pistions. he prefers builds in the 180-190 range for good tuning. i was a bit higher probably closer to 212
the change in the base run map in lower tq and hp ranges had lower spark advance tables, the higher timing numbers shifted where the torque to the left where it started and gave it about 5 hp more from the 255 map in se race tuner tables. Im guessing the 255 table map had lower spark advance to deal with pinging, as safer bet , when i had the dyno map in after I turned acr back on I had to take a cpl degrees out around 2500 rpm range of it. bike did ping if it was a bit under rpm for speed I was driving and throttle was opened too far for the rpm range

Don't take this the wrong way because I'm not trashing your bike whatsoever but I don't see how in the heck you got those numbers on that dyno sheet with the AFR off that bad.
You just need to find you a good tuner in your area and have it tuned. Where abouts do you live?

to me unless you are racing or a very aggressive rider consistently redlining the engine the 255's seem to me how most hd riders ride. Someone above mentioned that you choose a cam as per the way you want to run the bike, I agree.
Overcamming your bike allows for bragging rights but less enjoyment in riding.
God I sound like my father. lol

I looked and tried lots of cams, and not just HD cams, I rode bikes and swaped with guys I ride with, by far, to me the SE 204 cam was the best one out there, I love the sound and power it makes, I ride 2 up and single and have not had a cam impress me as much as the SE 204, the other cams you guys are talking about are not much more then stock. I would not spend that much to gain that little on my bike, but thats just me and my opinion.

then you haven't ridden one that was properly tuned with an Andrews 48H or 57H. They blow away all 3 of the SE cams mentioned, 254e, 255, and 204. Now I will say I do love the sound of the 204 idle. Much better than most I've heard.

I Just did the 254e cam on my FLHTK '11. It's definitely louder and a little more kick.

way up on border of usa and canada niagar falls thought the guy that did the dyno 45 miles from me was good but found out he just tries a few programs and done 400 bucks for 1 hour and 40 minutes of killing time keep in mind bike runs along about probably doing about at a cpl grand then they open throttle it so i dont think alot of the afr in ghe bottom range of maps get used much for the dyno run u see it sitting about 14.6 then rties to catch up to the 13-12.6 range for wot bike had se mva heads not stock and 10.1 pistions not the usual flat tops in motor that probably why the 255 is questioned i did see a map posted a while ago with about 110 torque and about 108 hp that i think was inflated whos knows maybe mine was too i wont go back to this tuner again i believe he is more of a power comander guy and is supposed to real good but guess i was a real fast buck so i wont go back nor willi recommend him to any one burn me once only shot your gonna get the thing was great on hyway and large mountain hills id like to throw an andrews 57 in it ends up with a lower ccp with same parts in motor

That, my friend, is what is known as "over camming". 259s aren't real bad if set up properly, but they do need more compression and headwork to work. They are not bolt-in cams.
This whole thread has been about SE cams but my pick for a stage 1 103 is Andrews 57s.
