Title: 110 twin cooled to 124LC air cooled conversion
Post by: damonhoglund on September 04, 2019, 04:58:41 PM: HI, I am trying to replace the 110 twin cooled motor in a 2016 Road Glide CVO Ultra with a S&S 124LC motor, and I am having quite a bit of trouble with the watercooled temp sensor. I am wondering if I should just buy a air cooled wiring harness and BCM, I already have a thundermax tuner, and I am stumped,and could use some help, and, or guidance, and it woud be greatl appreciated, thanks in advance. Have a blessed day.

Motor warranty goes away if you swap heads. Actually most dont want the hose kit and opt for the interface drilled anyway so that is a teardown anyway. I can help you get this done whatever route you decide on. Nothing wrong with just making the 110 air cooled either.

Post by: Hondo2doc on September 04, 2019, 06:42:46 PM: I recently had a new S & S 124ci HC installed to replace my 110 ci on my 2015 SESG. Everything went relatively smooth. Used power comander for tuner. Bike runs like a raped ape. But.....but not able to eliminate engine light from coming on and staying on. I can’t remember the code number but I think it’s either water pump (which is gone) or temp sensor. It doesn’t bother me.

But perhaps you know a way to stop the engine light. I’ll keep following....good luck!!

Post by: damonhoglund on September 05, 2019, 09:14:58 AM: I already have the 124LC installed and running, but the electronics thinks its overheating because of the water temp sensors 130 degree rating so we tied the water temp sensor to the head temp sensor, as of now we installed a set of love jugs, and trying to see what happens. If this does not work I think the wiring harness, and BM will have to be changed out, and in doing that I think I will lose some of the CVO features, but I truely dont know what will happen once thats done.I am deep into this modification and just want to get this bike reliable and back on the road.

Post by: damonhoglund on September 06, 2019, 09:57:40 AM: So thanks to HD Street Performance, and Joe from Powerhouse cycles, I have been led to a solution for my problem. In case anyone else wants to go from a twin cooled to a air cooled motor, I would strongly suggest contacting either of these two. They were very helpful, and patient with me, thanks a lot, I really appreciate it.

Post by: Thom on December 07, 2019, 12:04:08 PM: My bottom end went out as well on my 110 and took the rest of the motor with it. Is your 124LC conversion completed? If so are you happy? Does all of the electronics work correctly? Such as MPG, Oil Pressure, Temp, ...? I'm seriously considering this as well. Did you change the clutch? I was told that the 110 clutch won't handle the 124.
Thanks for your prompt response to this matter. If you would like to PM me, that would be great, would really like your feed back on if you would do it again.

Post by: damonhoglund on December 19, 2019, 05:48:58 PM: I have been nothing but disappointed in what Ii have been through with putting the air cooled motor on this bike I plan on selling it and I'm probably not going to get another bike.

should have just built your twin cooled motor to 124" instead of going with a crate motor

Post by: grc on December 20, 2019, 08:12:19 AM: I still don't understand the desire to convert from a superior cooling system to an older and less efficient system. There are lots of reasons why the automotive folks abandoned air cooling for water cooling a hundred years ago, and you don't see anyone converting water cooled automotive engines back to air cooled. Why not go all the way and throw an old shovel or pan in the chassis, 3 speed crash box trans, and cable operated brakes?

Post by: timo482 on December 20, 2019, 01:49:17 PM: i feel bad when i read threads like this. im certain that somebody gave the poster "good advice", took the money, and now it does not work. changing engine family is a BIG job. performance enhancements should always be looked at though the eye that a failure could occur. with a fuel injected engine big engine changes need to be done eyes wide open to the risk of a electrical mistake. its not broken, its built wrong, and its sad.

No more master cylinder recalls if we go back to cable operated brakes

;D OK, true enough, but when Harley sourced the brake cables to China they would eventually have to recall those as well.
