Hello

I have a 2018 fatby, which I added some rinehart slip ons. I would ike to install an arlen ness air cleaner. Do I have to tune the bike after I install the air cleaner?

The bike is still under warranty so if I install a tuner that would void that,

any ideas or suggestions are welcomed.

I've discussed with my workshop about putting on a full Rinehart kit and they recommended getting the bike dyno tuned after to get the full benefit of the up grade. Have Screaming Eagle big breather on it already and will probably stick with that.

 

Here's my 2 cents on the topic...

There is nothing better for getting top performance and the best running engine, than a dyno tune... period...

I will add the caveat, a dyno tune by a competent dyno tuner... Not everybody with a dyno is competent, and a bad dyno tuner is worse than useless...

However, I don't believe for Stage I mods (high flow air cleaner & high flow exhaust) that a dyno tune is necessary for a street bike....

My experience has been, on several bikes (3 of mine and 3 for good friends), we have gone the PowerVision tuner route, with a map from a reputable tuner (FuelMoto in my case), and then a couple basic auto tune sessions with the PowerVision tuner... that has given us excellent running street bikes...

In my case, I bought the tuner for $400 (about the cost of a dyno tune in these parts), for my first bike... then each additional bike can be added to the tuner for $200.

I bought mine from FuelMoto. I have lifetime map support from FuelMoto and also support from the PowerVision manufacturer, DynoJet. Additionally, having the tuner has allowed me to "upgrade" from the Stage I mods to a big bore kit on one bike, and a crate engine on the other bike... Both of those were dyno tuned after the bigger mods, using the same PowerVision Tuner I used for the Stage I map download...

I had an issue with the one dyno tune, sent a data log (done with the PowerVision tuner) to FuelMoto. They read the log, adjusted the tune, and now all is well....

So my advice, if you are OK with voiding your warranty early.... Get a PowerVision tuner (from FuelMoto if you can) and just do a good map/auto tune for your stage I mods. You will be set up for any change in future tuning needs for this bike. If you add another bike to your garage, or sell this bike and buy another bike... pay $200 on a license for the new bike, and you'v got a high level tuner for that bike too...

If you want to keep the warranty, and have no interest in "upgrading" your Stage I mods, you can go with the Screamin Eagle tuner... It will supply a Stage I tune map, within EPA guidlelines, and that tuner is approved by the MoCo. You will have a safe, acceptable tune (not the best, but this is a street bike) and save your warranty... They can also tune bigger mods, but being it is an EPA compliant tuner, it's kind of a waste (IMHO) using it on bigger mods...

Good luck with your decision and your mods...

Really appreciate all the info. I am still fairly new to riding and wrenching so for now, I am gonna save the warranty just in case I jack something up.

My two cents, HD dyno is a rip off. They run it to make sure the MAP is correct, they do NOT fine tune the parimeters of the MAP but they should.
You can install the MAP yourself, you can tweak the MAP yourself. HD install the MAP without a dyno would be the way to go as NOT to void the warranty should any issues ariise.
Whichever you decide, insist on that file they used to MAP it, so you're able to tweak it with a laptop.

Thank you.

Thanks Hattitude. Will ask more questions before doing anything about it.
