Screamin' Eagle Stage IV Upgrades | Harley-Davidson

Nobody says "no" to more torque and horsepower. Screamin' Eagle components are the key to greater acceleration, increased passing muscle, & more of that rip roaring raw exhaust note that makes power more than a little addicting. Watch to learn more about Screamin' Eagle Stage IV performance upgrades.

[@timmurphy2825]

Whatever stage you do, try to get it done within the first 60 days of purchasing a new mc so it's covered under warranty.

[@aaronhodgeson438]

Where is that stated? Dealership by me just said as long as they install it it is covered under the warranty.

[@timmurphy2825]

@@aaronhodgeson438 Brand new, as long as they do the install. It is covered under the standard 2 year warranty. If you take out the ESP, extended service plan, you must have the stage kit parts added to it and triple check the documents making sure it does state that. Verify with the dealership what 3rd party modification parts like headers or such could void either.

My M8 107" to 114" needs to be tuned properly. The prostreet tuner is not the correct one. so i'm going to have it tuned with Dynojet power vision software on the dyno instead of the TTS tune.

Big questions does the bike run hot after the install?I had my 2012 done a few years ago and it may of had the horsepower upgrade but it ran extremely hot. Has anyone that has had this done with this stage 4. I just bought a 2019 cvo street glide. I will not be doing anything to it.

[@jsandrieux]

I just got the Ohlins suspension installed on my bike. It rode differently / a lot better than before. The HD Tech stated , "suspension has not even been broken in yet. It will feel even better" I considered a 131 Stage IV kit instead of a 135 Crate Engine replacement for my 2022 Street Glide Special Is a 131 IV kit now cheaper since the 135 Crate Engine is being produced? The wait for my area in Pennsylvania for a 135 is likely up to December or later when it is officially released for here compared to scheduling a 131 kit upgrade next week. I am just trying to weigh my options. Looking for any comments, thoughts, or suggestions from anyone.

Hey, you will keep your original H-D warranty as long as you only use Screaming Eagle parts for the upgrade. For all other questions on upgrading to Stage IV, we recommend you stop in at your local dealership, or you can check out page 416 and 417 in the 2020 Harley-Davidson Genuine Motor Parts & Accessories catalog.

[@framusburns-hagstromiii808]

Hmmm...are these upgrades sequential and inclusive?..does the stage IV kit include all the changes from stages I thru III or are they each unique requiring removal of some or all of the parts from a lower stage upgrade in order to install a higher stage upgrade? Wondering why Harley doesn't just offer Motorcycles from the factory with engines that already have these upgrades as factory standard ....could it be because of $$$???? Pretty sure riders would pony up the bucks to get the engine they really prefer to have in the bike from the factory...

[@sebastianshaw210]

I have almost identical questions, seems like they stack on and have to be invested each stage wise. Their justfication seems to be not everybody wants to spend 10 grand plus, or need that much power, some are happy at lower stages. Like your suggestion however i would also prefer they just gave a choice of a performance version straignt out of factory like mercedes does with AMG or BMW does with M

@@harleydavidson so in essence, in order to go from say: stage 1 directly to a stage 4 you'll have 2 brand new useless cams sitting around.. I guess it's more beneficial to just do the stages in sequence til you feel like you have enough. Defeats my one and done theory.

I ride close to redline to get the most out of the engine.they start building power stock at 3to 4500rpms. Engine runs cleaner that way and there is less carbon buildup. Bikes are made for it people are just afraid to do it and lug the motors down to 2k rpms and shift at 3k.
