SG's that haul a$$
I have a Carb for easy tuning, so what I am doing is less applicable in your situation. Nevertheless, I am putting the following on my FLHX, upon arrival.
V&H True Duals with Oval Slip-Ons
SE 103
SE Flat-Top stroker pistons
HTCC CNC Ported heads
SE-260 cam
45 mm SE (mikuni) Carb
Compression releases
variety of small changes...pushrods, Air cleaner, ignition map, etc.
I am hoping to get 120hp, 110 Tq with this setup. Am awaiting the real world, seat of your pants report, which I should have in about a month. I omitted the 6 speed, don't like having to downshift to pass!
Anyway, your are not alone in your search for a few ponies.

The most important issue to maintain in the mind when doing any form of build is the balance and compatibility of all parts together, and this is where a tried and proven builder's kit from a respected builder comes into play as the most practical, reliable and, in the end, cost effective solution. By experience, I can enthusiastically recommend http://www.zippersperformance.com/. Look their site over carefully and, especially, research their Muscle 107" or their Muscle 120" kit. Call them and talk to them. You can also view the CVO forum www.flhrsei.org and look at the extraordinary library worth of info available there from members on builds for both TC88's and CVO 103's. In that forum, you'll find a large amount of comments, including a vendor thread, about and from the folks at Zipper's Performance. You'll also notice on the Zipper's site all the tranny options, including my favorite, the Baker's six-speed builder's model. You'll get straight into the world of how to best match parts and do the modifications necessary to make sure you build in reliability. Anyway, there's some thought for you. Good luck on researching your build and putting your plan together.
Best regards,

I agree a big-bore manifold is indicated & I have one.
As far as pistons, Harley has worked all of the combinations of pistons, heads & dyno-ed each. I have picked the combination of parts, from their figures, upon testing. Many of their packages with HTCC heads, do have HTCC pistons, but not all. In the Screaming Eagle parts catalogue, available as pdf download from their site, they detail this. On page 18, bottom row, 2'nd from far right, is the configuration that I am going with.
I chose all Harley mods (except exhaust) in hopes that if I have trouble on the road, that any Harley dealer could have a chance of fixing.
Anyway, if you have information that would benefit me, I would be glad to hear it.
Now, back to regular scheduled programming...Bryan's need for speed.
Thanks for the reply,

103FLHX, You might want to do some homework, but i beleive that if you go with htcc heads, then you need to go with htcc pistons, there is a htcc intake manifold, that is required. My $.02, just thought you had some time before delivery to look into it.

I choose this copmbination, so I hopefully won't have to revise anything in the future. I don't need any more power than the bike is reputed to have, but I don't want to make a few mods & then next year replace half of them again. I tried to do at it the start & leave it from there. Time will tell, if I am truly satisfied. Several months of research have led me this path. I had almost ordered a JIMS 120", but could not find any good answers about is reliability.
Good luck with your search

I remember you from the chopper forum! Glad to see you here! I see (in your gallery) you still have the good looking chop and better looking wife!
Now I see you added the sg to the stable, very cool! Now I know youâre serious about performance so check out the links I posted below. Donny Peterson writes for American Iron Magazine and he has this **** down to a science. He even does consultations if you want to go that rout. He will help you get it done right the 1st time...
How much power are you looking for? I plan on doing a 95 kit (heads and jugs done at a shop not from HD) with 31G cams, rollers and all the other goodies myself this fall. I hope to have her dialed in to about 1hp per cubic inch (rule of thumb to stay reliable). Let us know what you plan on doing!
