Doing some mods and looking at stuff in the HD parts catalog and began to wonder. Just what Screamin Eagle parts are in a SE 110 engine as it comes from the factory. I know the jugs and pistons are larger put are there special heads on this engine or just one that say SE on the side. And better cams? And is there any diff in the air cleaner beyond what is on the 96 engine?

Hey there,
I cant believe so many people have read this thread and not replied to you , i am certainly no guru on the subject, but in an effort to help out?

All I can tell you is what I know about my standard 110b donk. The heads are set up with high lift valve springs, and have larger valves, these heads will breathe well, and have auto de-compression. Cams are SE 255. Thats about it. You might find other threads  about this subject if you have a look.

Not sure about your AC but mine has a SE heavy breather, which is much different to the standard issue 96 AC

Hope this helps

No guru here either but I.m sure if I give the wrong inofmation it will get you some more info  segle is correct about the heads. The backing plate on the ac is opened up to breath better but that's about it for pre '11 years. I understand that the .11 have the SE compensator. Good luck

I think there's also an actual EAGLE inside each engine SCREAMING to get out...

I do know that these two parts are not in the 110 motor because I just put them in.  The SE Compensator and the SE billet cam plate.

I was under the understanding that the new SE bikes are now coming with the SE Compensator 
I know on the 07,08, 09 they were not included.

The cylinder heads are indeed unique to the CVO 110 engine, with a hemi style combustion chamber rather than the bathtub chamber on the standard TC heads.  Bigger valves and stronger valve springs are included, as well as automatic compression releases.

The cams are unique to the CVO 110 (SE255), and of course the actual pistons and cylinders are also unique to the 110.  The engine cases are stock cases modified to fit the larger cylinder spigots, the crankshaft (flywheel assembly) is the same stock part found in the TC96, as is the cam plate and oil pump.  The primary is the same as the TC96 with the exception of the clutch spring and the compensator (2010 and later), but the clutch release mechanism is changed to hydraulic from the standard cable.  The transmission is the same as the TC96 models.  As for the air cleaner, that varies by model.  The CUSE models come with the smallest difference, with only a few extra holes in the black plastic airbox to let a little more air in.  The SESG comes with the Ventilator air cleaner from the catalog, as did the SERG in '09, and other models have come with the Heavy Breather.  What model do you have?

Go to the catalog and look for the 110 street legal kit that Harley sells.  That is the same stuff that comes from the factory on a CVO model.
