Well, thanks to my friends here, who obviously know more and definitely care more than HD, I'm back to waiting for the cams. which should be in next week. The bike goes in on Tuesday. Thanks to Harry and djkak for confirming compatibility of the SE 50mm TB with the cruise. I spoke to the SM and told him to take the TB over to another cruise bike and tell me it's not compatible. I told him I took the SE catalog picture into my garage and compared it to the one on my bike. Looks identical to me. He doesn't know why Tech Services told him what they did, or why HD doesn't promote this TB for cruise applications, but he wasn't surprised that it would work fine, even though they said it wouldn't. You guys are the best and this site rules!!! Hoist!

That's hilarious.  All the published literature says "no cruise."  So you believe it.  After all, who'd expect them to limit the application unnecessarily and by choice?  That's what I get for believing Harley Davidson.  Dipsticks!

The 50MM Throttle Body does work with the 2007 110 inch arrangement. In fact the SE throttle body is pretty much 'plug and play', everthing is idenitical to the stock 48. Even the TPS voltage was dead nuts on. Also, the flanges that come with the 50 MM throttle body are correct for the 110 inch heads. Dont let anyone try to tell you to waste your money on the Kuryakin adapter flanges,, YOU DONT NEED THEM, and they wont work.

You are going to see a major improvement with the 50 MM swap. I use the DTT ignition and revied one of my recent data runs. Fuel starvation begins at 4800 rpm with the stock throttle body. You can blame the new injectors on this one and a simple injector swap would do a lot of improvment too, But the 110 inch has lots of room for deep breaths and the larger TB will really help that out.

Make sure you share your performance story when your done.

Thank you very much for that erk! I'm convinced that HD either doesn't want the liability of hot rod motors running on cruise, or Marketing just doesn't have a clue! But I'm happy I'll be able to move forward with this work now. The performance story should be an interesting one, as I'll be tuning and Dyno'ing with 3 different exhaust setups. I'm real curious to see the results of that comparison too!

On a side note, I called to see what's holding the cams up. I found out that there's a typo in the '07 SE Pro Racing Parts Catalog. They list the SE251 cam as P/N 26466-06. This is an incorrect P/N. The correct P/N for the SE251 cams is 25466-06. This error held up ordering my cams as the wrong part doesn't show up in the computer.

Hoist!

you may want to check out the valve springs on those heads.
i put the 251 cams in my 103, but had to change out the stock springs because of the high lift.

 .579 Lift? -- comon.. Thats conservative, besides, the 110 inch Screaming Eagle heads should be good for this lift anyway. It may be borderline, but i dont think i would waste my money for 4/1000s over... I would rather limit my RPM to 5800-6000. The crank in the 110 inch motor, as i understand, should not go over 6000 RPM anyway. I think the 251 is within the safe limit of this motor for both top and bottom end. If somone knows for damn sure, lets here it

Evil,

The heads will handle over a .609 lift which is what the 260 cam is that comes in the stage2 kit for the 110.   The heads in this kit for those with a 96 or 103 looking to go bigger are the EXACT same heads we have already on the 110 engine.  I verified this with Harley Spock and Tech and got a break down on the parts list with and without valve train in them.

The other thing you have to note is that king did not have a CVO 103 he had one built for him.  The cvo 103 had clearance for 630 lift despite the original reports of .550 lift max that harley shared with people myself included. 

As long as there are no issues with anything in the head the 110 heads will handle the .579 lift from SE 251 cam without issue.

we've already been through this with a member who was banned from the site a while back so i don't want to get into a whole discussion about it, but my engine is the exact engine that came on the cvo's.
i am however disappointed to learn that the valve springs would have accommodated the lift.
i would have saved alot of money on the cam change.
the 550 lift b.s. was the only info available at the time and i did not want to take a chance.
oh well, live and learn.

don't get your feathers all ruffled up.
i just don't want to see anyone damage there ride.
i thought it was a legitimate concern.
just trying to be helpfull.

Sorry Kng103 thought I had remembered you having that built from the posts we had back in the day when you were going about it, cvo or not I still don't think they discriminate about people being here, but that is a whole nother bag of worms.   Glad you would rather see someone be safe with the motor than run the risk of hitting a valve on a piston.  Not quite sure what happened with the person that is no longer on the board ...  do you remeber the screen name of the person that was kicked?

There was a post about the change in lifts after some bantering that went on about the heads on the CVO103 that clarified the lift.

[ccr]

...  do you remember the screen name of the person that was kicked?...

I know of a whole lotta folks who have committed screen name suicide, my husband was one .......... but only remember one member being kicked, and that person is back here with a different screen name.  If you are talking about Mike -------- He pulled the plug on himself, not one kicked him away from here.  He and I talked a lot off line and I begged him to walk away for a couple of days to calm down before he did anything drastic.............. well ...........

Curious too, Kng, sure miss the pic of your son.  Isn't it funny how we associate things with different members here?  Actually, I have turned off all signature pics and so have no idea if he is back of you or not.

Hoist, why the SE 251 cams and not the SE 258 which will pull strong all the way the to 6000 rpm'd ? The SE 258's seem to suit this motor better.

[evilroadking]

KNG 103,
Currious, what catalog did you get your information regarding the the SE251 Cam and the 50MM Throttle Body. Im looking at the the 2007 Screaming Eagle Pro Racing parts catalog and on page 30 there is no reference that states the TB does or does not work with cruise control. The catalog also list the correct part number you provided for the 251 cam. And I see no refrence at all for the 110 inch stage 2 kit. The 2007 Screaming Eagle Pro Racing catalog is on their web page as well. If interested, here is the link.

Also, do you have any information regarding the intake and exhaust port sizes on the 110 inch heads?

Because he's a big pansy-ass who is afraid of not doing following the little twirp mechanic at the dealership tells him he can have  .  That, and he's a staunch proponent of maintaining all service standards in comformity the factory warranty.  But, basically, it's the pansy ass thing  .

[Unbalanced]

Evil,

Stage2 110 came out after the original catalog was released which is why you don't see it in there.
but at this time shows discontinued??  epa ??  something else

The head spec's are also in another post they are intake 2.080 and exhaust 1.625 made by Ferrara.  The Ferrara brand of these valves are only available through harley.   They are being blocked from being sold even by people who are Ferrara dealers / resellers.
