  They seemed to have broadened the curve with some nice gains

I have the 117 kit on order, not planning on headwork. I am going to go for the compression bump with the thinner head gasket. My question is: I saw one post with a 0.027" cometic head gasket, and most with a 0.030" head gasket. Is there a drawback to the thinner gasket? I understand I will need to do deck height checks, just wondering if it works from that standpoint does it cause other problems?
Thanks

I've done a number of 117" conversions, and find pistons anywhere from .006" to .011" in the hole. The front and rear cylinders are NOT necessarily the same/equal.

Thanks! Did you ever use a head gasket thinner than 0.030"?

I've never used a head gasket thinner than .030". I'm sure Cometic can shed some light on their .027" H.G. They're a top shelf gasket maker, and get plenty of feedback.
After several years of my suggesting to relocate the rivet areas (early on, extremely hard to get the pushrod cover clips on). they sent a drawing, and made the change to this, which is now standard production.

Nice work on the gasket mods! hope they compensated you:D. I will most likely go with the 0.030 that seems to be a tried and true method to get a couple tenths of compression bump.

Here's one we finished up last week.  Customer was looking for mid range/top end pull and I think we delivered that pretty well.  We used SE cylinder/piston kit, Rick Ward CNC heads, SE 58mm TB, S&S 635HO cams @ 10.5 compression, and a D&D Bosszilla.

This post is worth resurrecting this old 110”-117” thread. It has to represent one of the best sets of dyno numbers from such a conversion.

Amazing work. Twin cams are far from dead, and this is serious proof.

145HP & 152TQ from this combo. (See Dyno Chart on page 97.)

Agreed! I may try and replicate this one day

Vmax-Vrod,

do you still have your CVO collection? Have you kept it up to date?


Just curious, jealous too

Yes, I still have them; and have kept it current through 2021 so far. I’m surprised anyone remembers, especially since my old account went dead.

We’ve had short conversations before, all good. You stated your previous handle when you introduced yourself as V-rod Vmax. I'm surprised the mods didn’t catch it and do whatever they do. You sir are royalty here when it comes to CVO’s.


I’ll race you anytime and I’ll run what I brung 

Matter of fact you need to bring your daily driver to one of the east coast GTG's, you got something that's running??

With that group how could anyone forget?

I didn’t think my intro post was enough to cause a stir, I guess. I surely don’t think of myself as royalty. I’m just another guy who loves CVOs and bought way too many. LOL. I think of myself more as the guy who never sells or trades, and just buys more all the time. ROFL.

I think my VMAX would fair pretty well against most stuff without breaking out a Harley. I have so many 110s, I’m having a couple of them redone to higher spec than their original mild builds.

Maybe I could bring a CVO Springer with a 145hp/150tq 117”. I’d call that “running”. If I can ever get ahold of Fitzgerald (he’s covered up), I could get him to do one of my V-Rods as a 1,487cc / 180+hp monster. That would be interesting for the east coasters.

Coming from the Triple Threat man, that’s quite the compliment.

You bring anything you can ride, ain’t no dyno numbers gonna scare a few I know of, 118/135 is all I got.  I’ll take my antiquated bagger and we’ll try it across the mountain and thru the valleys for chits and grins. Should at least be an HD you ride and a CVO is a plus.

You’ll experience some southern hospitality at it’s finest and good riding to boot. There is always some fine rides too.  One next month in West by god Virginia, and then in September my favorite place to ride Maggie Valley. I’m still finding new roads to ride there. So make some plans and bring some friends.

And just a few CVO’s, you’re being modest


The ride from Maggie Valley to Cracker Barrel @ White Pine TN  on I-81 is a white knuckle ride doing if up to speed. It’s only 70 miles on the big road, plenty of straight away in the end to make up some time if ya need to, Green flag at I-40. Early is best time. Not far from J&B, with my 117" kit.

Post yer time

Hi Folks,
Got myself another CVO this year. ‘16 FXSE Pro Street Breakout. It’s got an RB Racing LSR 2-1 B style exhaust (2” primaries & baffled), S&S TC3 oil pump/cam plate/premium lifters/chain tensioner and adjustable pushrods, with Wood TW-777 cams. Heavy breather elite AC is stock. The bike also has a ThunderMax Autotune on it. I live and ride at 3,000 ft elevation.

I just purchased the 117 HD kit for the bike. Having Yellowstone Harley (Bozeman, MT) do the install, break in and dyno tune this winter.
I’m going to have them send the heads out to be milled/ported/polished with new guides and springs as well to bump up the compression.

I’m not trying to build a top fuel drag racing bike, but I do run out my bike frequently, and definitely see triple digits every time I ride…
I’m trying to achieve a balanced 130/130 max output from the build. I do enjoy streetable manners at low speeds.
Looking for 120 ft/lb at 3k, 130 ft/lb at 3500-5000, and back down to 120 ft/lb at 5500. I’d like to see 100 HP by 4K and 130 HP at 6K.

My question is:
Will this build be under-cammed with the TW-777 in it? I cannot find one single 117 build dyno sheet using this cam, they seem to stop being used beyond 110” builds. I am definitely not going to use the 259E cam in my build. If the 777 is just not going to work with the 117” to achieve the results I am after, then I am looking at the T-Man 590PS-2 to do the job.

Please let me know your thoughts on the Wood cam I have, and what you would recommend.
Thanks!
