Hi guys,
I would just want to know if someone has done the installation of the biggest S&S engine and if you got some pictures of it and of the process to install it.
I know that the engine is higher than the stock one so it's not a plug n' play job, but as I know that nothing is impossible in the US  
And also what are the feelings with this engine...

[GMR-PERFORMANCE]

Let just say that it will bolt right in       Even so the 145 is not your standard touring package and really would never be embraced that way. 124 low comp engine bolt it in and go. We will have the fourth 124 LC engine  that we have done this month here Monday. Price point is great makes killer power etc. The 145 is more a mid range and top end kit even at 145 CI it could be without a doubt altered to make low end power. The T2 case for that will not be ready until fall, however it one where to buy the t2 case now and special order it without a few items such and engine could be put together long before the "production" case is out. just sayin.

[Mr John DEUFF]

OK it's good to be advised by people who knows what they are talking about because you are right I looking for a low RPM torqued engine. 
Most of the time I ride my bike between 2000 and 4000 RPM.
 You're talking about the 124 LC (for low compression I think), is it better for a touring bike than the "normal" 124? What are the differences between them?
As I want to change (not now but as soon as possible) my engine of my FLHTCUSE2 I would like to install a carburated system to have a more "expressive" engine. I don't mind about performance.

I put the stock SE 120R into my '08 and all I can say is that bike came to LIFE - I honestly dont want anymore in fear of breaking parts on the bike.  The bike does awesome and I am a speed freak - but pulling around 130 squared at the rear wheel is plenty for me...bigger is better but I needed reliable as well...so far it is.

COULD, it be touring-type power?.........yes.
The ones we have been involved with, so far, have not been.

 145" motor is too tall to fit in frame without heavy modification. Long stroke increases piston speed and
Heat! Lowers your red line rpm. Pistons have very short skirts = low mileage between rebuilds.

[Mr John DEUFF]

OK guys I have understood that 145ci engine is not a good idea for an every day riding bike.
Could someone explain me the differences between the 2 S&S 124ci engines, the LC and the "normal"? Which is the purpose of the Low Compression one?

The LC option actually pushes the torque quicker, than that of the .640 cam-equpped counterpart.

Here is a 585 vs the 640 .. as you can see the 640 does very well. Set is very close and really pipe to pipe nothing is being gained one way or the other.

We just completed two of those LC 124 last week. Both where every close to HP and tq number , Another is being dropped off today and it's going into a 07 bike so 55 HPI cable with a DD7 trans pwr dual head and standard crusher mufflers . Nothing like real world in house testing.. always a great time to see how one will stack up against the next 

[Mr John DEUFF]

Why do the red lines of the crate engine start after 2300 RPM?

[Dan_Lockwood]

Probably just started to record the pull after that point.

I guess you could start the pull at 3000 rpms and the graph would just start there, but we know there is more to be seen below that, it just wouldn't have been recorded that low.

[GMR-PERFORMANCE]

It is how I recorded the run . It you hit the button and wait 1-3 seconds you get the straight up line if you hit the button and go WOT you the just a starting point. Does not matter.

The tall gearing the new bikes have will effect the clutch, and there are times where it  will not hold at 2000 RPM and a WOT pull, being that its not really a real representation of how the bike is ridden on the street. 

[Mr John DEUFF]

  I got it!
That said, what are the difference of them when you ride them? The LC is more rideable in the low RPM?
Which one one is the more funny or pleasant to run with when you're not a high speed rider like me, because I like to cruise between 2000 and 3500 RPM.

Just put the high compression 124 in my touring bike and love it so far. Most of my riding is done around 3K anyway even when 2 up. Tere is really no comparison with the 110 adn the 124. The 124 feels like the bully on the playground. My 110 had been punched out to a 124 and didn't feel anything like this motor.

we sell about 50/50 HC vs LC engines. Both are very nice out the box. AS you can see the tq curve really very nice on either engine kit.  If you are going to buy one I would suggest that you get in touch with the shop you choose and have a conversation. A shop that has built, installed and tuned them in house would be your best bet.   Good luck on your new build
