I had mine powdercoated, I'm not aware of a stock HD part that's black. However someone else here may have that info.

 

Doing the math, if you have a PV2 or other tuner that can recal the VSS, you'll need to adjust your 'pulses per km' value to get an accurate speedo reading after the 68t swap.

This can be done in WinPV directly within the tune file under the Speedometer Calibration setting - But only on the newer 358-based tune files, you will NOT see this setting available in the OLD 357 tune files that are part of DJ's canned tune downloads. Why DJ is still providing 5 year old outdated tune files as "upgraded" tunes" with the PV2 is beyond me.

I have attached a zip file with both a HD dealer-supplied Stage 1 358 tune for SE intake and VH 2-2 Big Radius or shotgun 2-2 pipes, and a 100% stock unmodified bike HD dealer 358 tune. These files are for 2012-2015 Dyna / Softail 103 and are in PV format (NOT for CVO 110 or Touring, you need the 617 maps). You can use these as a base to migrate any VE, AFR and other settings from your old 357-based performance tune files. The Stage1 the is nothing special, it is just a "Safe" tune for breaking in the bike and compensates for increased air flow of the upgraded intake / pipes.

Open this stock file as the main tune, open your current 357-based tune as the compare, then copy things to the new 358 file, "save as" your new tune. you'll see in this new 358 tune there are a lot more options available that were missing in 357. You can tell if you have a 357 tune file by looking in the "Software Level" description field under "Tune Info" in WinPV.

As JimG stated earlier, we are looking at a 3% reduction in final drive gear ratio by swapping the Breakout 66T pulley sprocket for the Sportster 68T pulley sprocket. Stock ratio is 2.79 and we are going to change it to 2.875.

Given this, if we take the default ECM value of 2115 'pulses per KM' and add 3%, we will get a new value of 2178. However, since my speedo was always a bit off I am Thinking of starting with a value of 2232 (5.5%)
A 5% change would be 2220
A 4% change would be 2200.

 

LA, you should have bought a Rocker instead of a breakout dude. Us Rocker guys need someone with all the knowledge and research skills you got lololol.

 

I'm glad he bought the breakout. I told him yesterday he is a wealth of information. I bought me a set of night dragons based off of his info. Also got a really great price thanks to him.

 

Hah! you are too kind. Judging from the looks of your bike you don't seem to have any shortage of skills my friend. That's the nicest Rocker I've seen.

 

Glad to help- just paying it forward- JimG got me on the Pirelli track with his research threads, so we all gotta ultimately thank him for this tire upgrade.

 

Thanks. Luckily the breakout and the rocker share some similarities. That's why I keep lurking this thread lol.

 

No, it's cuz you are going to eventually buy one. wahahaaa

 

And live happily ever after .

 

Yeah but $157 for a little bit of performance and a better look is a hell of a deal if you ask me. If it was one or the other I would be hesitant
