I am considering installing the Screamin' Eagle Big Twin Compensator p/n 40274-08, in my '09 SEUC.
What are your valued opinions both pro and con?
Thanks

I can't think of any compelling reason not to, other than the expense.  After all, it's basically what's in the Trikes and the 2010 CVO's.  I guess my question would be, do you have an issue that you think this part would fix?  If you currently have a weak compensator that is causing problems, before I'd pay H-D extra money to fix their problem I'd invite them to do so under warranty.  If you aren't currently experiencing any compensator related problems but just want to upgrade for peace of mind or whatever, only you can tell if it's worth the expense involved.

I have one sitting on the bench, will probably wait until winter to install, the inner primary has to come off to replace it.  Rotor won't come out with inner in place.

If you install this kit follow the torque specs.  I know of two that were installed using impact wrenches.  Both failed in short order.

Really?   

This was not necessary on my 2007 SEUC...

About 1 in every 10 starts my 09 110 would make a clunking/grinding sound.
I just knew when it came apart for the repair I would see a tooth missing or broken on the starter or ring gear.
NOPE, not the case. After 35K miles of Redline primary fluid everything looked well.
A site member convinced me to replace the stock compensator and add the Screamin Eagle one.
Now, 2500 miles later the clunking/starting issues are just a distant memory.
I should have done it sooner.
If your having that strange sound at starting with your 110, NOW is better than later to add the SE Compensator.
IMHO

So this aggravating noise is only due to the compensator, and has nothing to do with the starter?

Perhaps the inner was slightly different for the SE's then, mine had a defined ridge around the front that the rotor hit right on, even turned the crank 180 and it was still the same, was hoping it would be the same, but with crank runout you just never know.

In my case    YES!

May not apply the same to everyone else's 110 but for me all was well in the primary except for the stock compensator.

Thanks for all the helpful responses. This is my 2 cents:

  Like SBB, I get the occasional clunking, grinding when starting.

  I have two riding buddies with 2010 CVO SE's and neither have had any similar starting noise issues.

  The MOCO now installs this compensator on 2010 CVO's and Trikes. Is this being done as a product improvement, or is it a fix to a problem on pre 2010 110's? What do you think?

  I have some long distance trips coming up soon, so I was going to pull the primary cover to inspect clutch, chain, and tensioner anyway.

  Though modest, my performance improvements (no-cat, TTS, Fullsac cores, Ventilator air cleaner), still increases HP/TQ by around 15% over stock.

  Much of my riding is two-up, fully loaded.

  And most important, I have not added or changed anything on the bike for over two months!!!

  Thanks again for for your opinions.

Both...  

I believe the prime motivator for the redesigned compensator was the scissoring crankshafts.  The SE compensator reduces shock load transfer to the crankshaft.  The issue is both pre and current 110's....as the crankshaft has not changed.

Dropped the stock compensator on my 08 SERK (had to). Replaced with an EVO Industries 30T sprocket kit (chain & front sprocket) and couldn't be more pleased. Been on the bike now for at least 6 months and run it pretty hard (Road Guard for the MC I belong to). Knock on wood, haven't had any problems to date. I know some are concerned about crank run-out, but as I mentioned, no problems to date.  Bought the "Wedge" Primary Chain adjuster (Southern Oregon Hot Bikes), but haven't had a chance to install it. The stock adjuster seems to be working fine.

That sprocket seems to just be a solid piece tied straight to the crank, no....slip.....like the original compensator sprocket has??

[grc]

Yup, the EVO industries sprocket is solid, with no compensator feature.  Considering all the various issues with these engines and drivetrains, there is no way I would eliminate the compensator.

Thats what I'm thinking, not without a welded crank and the bearing thing.....
