PCC,

I have a printed catalog coming. Can't get any of the MoCo's pdf files to load on my pc.

Understood, but I'm wondering if it might be quite simple to mod the CVO103 heads to work with the HTCC pistons.

Not sure why I spend time on such wonder-ments. I don't even have a CVO bike. I just enjoy figuring out what can work.

 link=board=CVO_TC;num=1104899854;start=15#27 date=01/05/05 at 16:03:50]Check the Screamin Eagle Performance Parts Catalog. There is a piston head compatability matrix which shows the two different types of 103" chamber designs and the pistons these will be copmpatibel with. Generally, with one exception I think, HTCC heads and pistons must go together. I think the CNC heads are the only ones which will accomodate flat top pistins and HTCC pistons a s well. It's easy if you just get the catalog.

There's a Screamin Eagle Parts Catalog scanned a posted on this site (in PDF format, if I remember correctly) somewhere.

Thanks. I'll have a look around.

Bubbarosa,

Fwiw, Imeasured the angle on the HTCC pistons' quench area. 30 degrees. So, it looks to me that it might be a snap to re-machine the quench surface in the CVO heads and use those pistons. However, I've no idea what the dome volume is, or what the chamber volume is on the CVO heads.
Regards,
Dave

Makes me think harley did that angle thing just to sell parts... so you cant use your stock heads with those 10.5 to 1 pistons.

Bubbarosa,

It looks [from pics] that the stock heads have a slanted quench area, which makes no sense to me due to the fact that the piston is flat. The HTCC heads have a slanted quench area, that matches the slanted quench area on the HTCC pistons. Would the HTCC stroker 103" piston work with the stock CVO heads> Good question. I suspect that it could be done. The quench surface in the heads may need to be re-machined, but that's not a bif deal, and it's dome in other applications. If I had a CVO and I wanted to add compression [and quench], I'd look into it.

Guys,

Have a look at this mornings post by Charlie of SBC, re. 103 SE Heads, it explains a lot.

He has done a set of SE 103" Heads for me. Will be installed on Engine  within the next few weeks.

DavidB,

Can not post before Dyno run, as the engine is a brand new 04 CVO 103". The engine that I am replacing in my 03 Road Glide was a 95" c/w SE Heads, reworked by SBC, with SE Flat Top Pistons, SE 251 cam, V&H Pro Pipe. It was putting out 98 HP and 104 lb ft Torque.

I will post dyno of the completed CVO 103" when engine is reassembled and I get down to Phoenix.

new to the forum, I have some experience with the twin-tec, my friend put the unit on his 03 SE Road King and has no computer skills. We tinker with stuff all the time and I got elected to do the program. It was a little complicated at first, but after talking with the man that designed it, who is pretty sharp, we started getting the hang of it, little bit by bit. The instructions are somewhat confusing, but I do like the unit.

The only real bug we still have a problem and not all the time with, is the fast idle warm-up time out to normal idle ie: open loop, closed loop.

All in all with the self tuning (to a degree) I would recommend the unit and especially since the price has gone down.
