124" Project Storm Breaker

[Ohio HD]

I had been planning to build a 110" motor for my 2009 Ultra for awhile, collected a few parts. I made a decision to move the 124" I built in 2016 from my 2008 FLHX to the 2009 Ultra. It's a strong quiet motor that makes good power and is always on and pulling. So that means I need a motor for the 2008 FLHX. What else but another 124". This one will be higher strung, more compression, higher performance cams, better exhaust, great heads. I have a goal, I want to cross over 160 SAE as far as I can, just because. We will see. I'll document what I do as I go along, it'll take a little while. Pistons are still about 8 to 10 weeks out. I won't have a crank built until I have the pistons in hand and weighed. I have most all that I need, but a few things still haven't shipped due to being out of stock.

This will be built in the house like the last 124" on my indoor work table. Saves heating the shop to warm for a few hours here and there. I need to clean the work table off so I can start cleaning the case threads, blow everything out, clean the cases, inspect everything close.

I'll post a list of parts I either already have, or are still on order. I think the list is complete and I didn't leave anything off. If I did I'll add the part when I remember.

Whats cams you looking at?  675?

[Ohio HD]

I'm planning to use 640's.

[hrdtail78]

Have done a couple 124's with that cam that hit right over 160sae.  One was a reworked 124 crate (5 speed) and the other was ground up with Ultima TC castings.  The ground up is my daily.

I'm not expecting that I would see anymore than just past or at 160hp. I'd be satisfied with that. I'll have Burns exhaust which should help to sneak up on the 160 number. Compression will be 12.25:1.

You have a good foundation to start with, I look forward to watching your progress. 

[Ohio HD]

Thanks Phil. And thanks for getting unobtanium cases for me.

LOL building it inside is the only way to go.

My Wife still laughs to people relating how I built a Panhead chopper in the family room of our old house..

She did get a little pissed the day she came in & I had a flywheel trueing stand on the marble coffee table lol (hey I needed a solid base for it). She calmed down when I told her I would buy her a new table when the bike was finished & she could pick out anything she wanted.......

I did mine inside also. Working in the AC is always better.

Seen in your PDF list you got Feuling cylinder studs and head bolts.
Understand the head bolts.
You not trusting the S&S studs?

[Ohio HD]

To my knowledge the S&S studs are from HD. I can't confirm that, but was told they were at one point. And they look 100% the same. So I'm just going a step further.

FYI - Feuling does not manufacture cylinder studs or head bolts. They simply repackage ARP studs with their brand name on them.

Yes I'm aware, just working from the presumption most on here know they are ARP.

Thought I would check out the muffler mount on the Burns system, and count the parts make sure it's all there. 1, 2, 3, all good.

I think the mount will be fine, the muffler is really light. I think I'll however replace the bolts in the transmission side cover with studs. Just to make sure they stay tight. If it were a standard long heavy muffler, the mount system would bounce around. I think it'll be ok as light as it all is.

I checked the fit of the R&R Cycles roller rockers with the Vulcan Engineering billet rocker support plates. They fit great, and have next to no felt end play. There has to be some, but it can't be more than a few thousandths of an inch.

These plates also have the setscrews to lock the rocker shafts in place. No rattling will be heard here. I also am using the Vulcan Engineering breather assemblies. They're precision fit from billet aluminum, and there will be no escaped venting from these.

I have been curious about the breathers from Vulcan. Seems the later stamped ones from Harley get a strong thumbs up, but I have always suspected the ability of a stamped piece of sheet metal to properly seal. I am paying attention to this.
