Hello
I have a 2016 streetglide and I am looking at swapping the engine out for the S&S 124ci engine or screaming eagle 120 this fall.
I am looking for some opinions on the screaming eagle 120 or the S&S 124.
questions
1. Reliability of the S&S 124 vs screaming eagle 120. I put on approximately 10,000 km per year.

2. Performance which is better, I am not a burnout or wheelie guy, but like to have the power when I want it.

3. When I upgrade my bike from a 103 to a 120 or 124, I will be replacing the exhaust, stock air cleaner and adding a programmer. should consider replacing any other partsS? I want to be able to ride without worrying if I am going to breakdown.

Cheers

 

Short answer: S&S 124".

Neither. Have one of the reputable builders on this site build a 124 to fit your needs. It will be more reliable, fit your want better and may even be a little cheaper.

 

WHy cant we Have a 124 with the Twin Cooled?
The 110 Twin cooled heads could be substituded

 

This advise is good.

 

The 124 LC is great IMO. I install a bunch of them. You will need to upgrade your throttle body, injectors and clutch as well as a good exhaust and air cleaner backing plate to match the throttle body.
It also has a better warranty than the 120st

 

I also agree with building your existing motor to 124",for one,its cheaper.two,you retain your factory VIN #`s & three you can build it exactly to your riding style & expectations.forget the 120".

 

Right on.
The 110" Twin-Cooled heads can be used.

Hey Guys
Thanks for the responses.
I am going to look at having my 103 built into the 124 or go with the S&S 124.
