Inner has to be pulled on my '07, but it's not a CVO....the picture put up earlier in this thread shows a relief where the rotor slids out, mine actually had a rise there.....weird.


The install PDF for this kit says nothing about removing he inner.  Sounds like you guys are witnessing some casting variation.  Isn't that precious....

I don't think it was just a variation in the casting, it was a deliberate lip, where the one pic'd earlier in this thread is a deliberate recess/relief.  I'd consider a variation to be maybe a random thickness change or something similiar.  I wish I had taken pics...I will when I open it up again.

That's strange too.  Can't think of any reason to make it more involved to disassemble.  Doing so wouldn't make line assembly any different or easier.  Wonder if there's a revision on the inner primary's part number somewhere between 07 and now?

There's not...  This has to be a casting variation or machining error....   :nixweiss:

Maybe multiple suppliers with slightly different molds and final machinings?  Both parts functional for line assembly so Harley never notices the difference.

Well,   here is the lip that the stator ring wont clear. 


And check out the incredible difference between the springs of the Factory compensator still in the stator ring and the springs from the SE unit not yet installed.  Literally twice as big.


And here are all the pieces with the SE unit on the paper and the stock unit on the left.

I guess they figured the 07 CVO's  were going to need this later so they gave us the clearance since we were going to have plenty of issues already to deal with. :huepfenlol2:

I'm not sure about the 07 and 08 but the inner primary hardware is alot better on the 09's than on the 06 and prior. The bolts use a oring seal and also the starter uses an oring as opposed to the oil seal.  The gasket between the engine and inner is a much more substantial piece than the little oring that use to be there.
But to answer your question, you'll need the gasket between your engine and inner and an oring for your starter. And thats ME assuming your 07 is like the 09.

Should have the SE Comp sprocket this week, I know from other 07 -08-09 that the inner will have to come off to remove the rotor.  Doc

The inner case to engine case gasket is more substantial than the old o-ring and the bolts have their own seal (they're also a one time use bolt so if you remove them for some reason you're supposed to throw them away and buy more).  Those things on the old system never gave any problem though.  So different and more substantial isn't necessarily a performance improvement.  The starter sealing and removal system is a lot easier to work with though. 

The starters themselves seem to be giving a bit more problem.  But at least they're a lot easier to get in and out.

Thanks to you all!!!

Mine is done and it is a HUGE difference during start.  I would not have believed changing the compensator was going to have such a dramatic difference in the way the bike starts.

I feel like my new starter has a chance at lasting now.

My dealer really stepped up on this one, and they did need to remove the inner primary to get it done.

Wow,   I'd like to know how they managed that.

Finally got to ride mine the other day after the switch,   quite a difference.
