First to admit I don't post much....I have a 2021 RGL. When I bought it I swapped out the breather to oval SE, RInehart DBX 4.5 slip-on's, and the SE torque CAM.

Every year my dealer does a winter sale and this year I jumped on it (this year it's 50% off of labor if you spend more than $1,500 in parts). Dropped the bike off yesterday. Having the 122 kit installed along with upgrading the breather to the higher flow version along with the S&S 55MM throttle body. Also, having the auto tuner installed while they are doing it. I still have just over a year of warranty left so will still keep it.

Question I have, is there anything else I should do while they have it apart. Numbers look like I will be pushing around 130 - 135 lbs (maybe a bit more) of torque when it's all done, installed and tuned. Going to do the bars in the spring (probably Factory 47's).

Thanks in advance!

if you really want to make sure they can't screw you over about your warranty, you should use the SE 55 Intake / TB parts instead of the aftermarket...also, I would bag the SE ATM and have it dyno tuned instead with the SEPST..providing you have a competent dealership dyno operator around...sounds like a powerful and fun upgrade !

 

Great advice by Mike and for good reason. A good experienced motor builder and dyno operator make the difference. If the dealership has techs that are not long term ate up with Harley performance they can leave a ton on the table and not even save you a dime.

Harley designed the stage 3 kits with 11-1 pistons, SE springs, and the SE-498 cam. For absolutely no good reason from a consumer standpoint that I can find when Harley went from the stage 3 107 to 114 / 114 to 117 to the stage 3 107 to 119 / 114 to 122 they castrated the performance with the SE-447 cam and weak stock springs. While keeping the 11-1 pistons that the SE-498 took advantage of.

Three years ago I did a stage 3 107 to 114 all warranty and EPA compliant parts. It makes 118 HP 122 TQ. What I am suggesting is that you have your dealership swap out the SE-447 cam and weak cheap stock springs for the designed for the 11-1 SE-498 cam and SE springs. The 498 cam still made more bottom end torque than the stock setup plus it allowed far greater rpm range and far more HP. If you jump to the stage 4 SE-515 cam only then you lose some bottom end torque. Naturally somewhat depending on exhaust chosen. My torque being lower 122 still respectable for a 114 in part because its paired with a shorter pipe softail.

Back to smart motor builder and dyno operator. I used the epa compliant S&S Superstreet exhaust instead of SE or non compliant. I used SE 64mm TB & intake. In my case motor builder and dyno operator were the same guy. He knew more air in and more air out the stage 3 114 map for the SE Pro tuner was not going to allow enough fuel timing tuning options to take full advantage of it. So he started with a stage 4 117 map. Bingo it worked he had enough tunability to make it a great running bike with beautiful dyno curves and a great AFR start to finish. This is likely why Mike suggested the SE PST instead of just the SE Pro. Harley shows dismal numbers on their stage 3 122 when it should make 125 HP. Its because lots was left on the table by the cam & exhaust plus some by the TB & intake. Would the average HD trained tech know or bother to guide you. Probably not. Please understand I am not trying to knock HD trained techs as they also have some outstanding ones. Only making sure you know how to get what you actually want and pay for.

When I read Mikes suggestion of the SESPT I thought that it would help take the mapping tuning challenges away as it allows for enough fuel etc to make for a good AFR through the range and through the gears. Not that I am a tuning guru because I sure am not. I am just able to follow the concept.

 

Thanks to both of you for the quick replies! Thankfully, the local dealership is outstanding and very realiable. The guy doing the builds and tunes is excellent and probably the best in the area. As to the warranty, they have been solid and one of the few dealerships that had it right all along and never played games when everyone else was. They understood Mangusson-Moss Act from the beginning. As with everything, ton of ways to get there but have to make a decision.

Bottom line, I think this will end up being about all I will do to the motor, suspension and bars next and then who knows.

 

keep in mind..violating the terms and conditions of your limited factory powertrain warranty by using non tested, approved and compliant aftermarket performance parts has nothing to do with MM stuff..it's a contract between the owner and manufacturer so don't confuse that portion with using whatever oil or oil filter, etc. you wish to use ... i.e, if you use the S&S intake TB for example and your engine blows up, you file a warranty claim, they send a warranty claim adjuster rep to inspect and notice that part is installed..they can deny your claim and nothing you can do about it..other than challenge them in court in which the chance of you winning would be like

 

Realizing that everyone has opinions, we are going to have to agree to disagree with that. If the part fits form and function it does not have to be tested by the manufacturer to be approved. That is the entire purpose of MM Act and the entire reason why the various dealers who were complete asshats, as well as corporate, got the FTC into the MOCO's panties. Legally, about the only thing you can do to truly get into warranty trouble now is to use non-EPA compliant parts. Does that mean someone won't run into an idiot here and there? Nope!

However, that is what the settlement means and how it is interpreted.

 

you need to read the contract terms and conditions in the owner's manuals..written by HD legal department..they won't even cover powertrain warranty if a HD dealership installs HD parts that aren't tested and approved for a specific year and model..i.e, if you buy a stage 3 kit for example, that comes with a certain SE cam, but you swap it out for one of their other ones..that's a violation

 

I agree that that is what is in there pre-settlement; however, that entire section has been now been superseded by the letter sent out late last year. Yes it's still in the book that was printed before the settlement but is no longer in effect. Let it go.

 

ok..just noticed the warranty details in the 2023 owners manuals haven't changed in the regard I stated..so maybe they'll update that for 2024... but all that matters for you, your bike and your money is that you understand it

 

Some good info already posted.

I bought my Street Bob second hand with that 122” kit. Despite the shortcomings of it (EPA compliant, wish they added more cam), it really does make for a fun ride. Rips pretty good and wide power band. Mine was tuned via whichever SE tuner has you select the appropriate base map.. These maps leave some to be desired but again a fun bike. Lots quicker and faster than the average Harley that’s for sure.

Regardless of tuner used I’d suggest having them put the bike on the dyno to validate proper AFR. Mine was definitely not spot on. I’ve since changed the cam, intake manifold and it will be dyno tuned via my Powervision. My intentions were to do this all along. If you desire more performance out of the kit after the warranty is up, that’s always a path you could take.
