Servo Buddy-Flapper Questions

[Ant]

2016 Gen1
Stock Exhaust

Been looking at the Healtech Servo Buddy, do you also really need to remove the servo motor and all cables?

I'm kinda thinking the easiest thing to do is just disconnect the two cables and that will leave the flapper open.

Last but not least do you really get a noticeable difference sound wise?

Appreciate any tips on this.

You can leave motor in place, just remove cables (this will NOT show any warning on dash but will store one in memory if GS911 or similar plugged in) Valve will then stay open. Not very noticeable noise increase as only opens between something like 4500 - 5500 anyway
No need for the ESE unless you don't want stored fault code, which won't make any difference to anything anyway

Caveat to this is if you run it for a long time you may burn your servo out, not a big deal, cheap used on Ebay, but happened to mine after  running it unplugged for 20k miles or so, servos don't like no load on them. (replacement motor is wayyy cheaper than an ESE dongle if you buy used)

Ant! I may have one for sale, a Healtech ESE if your interested, it is on my Gen 2 at the moment but I am going the BHP programmer route to delete the exhaust flap. Noise wise on the Gen 2 a massive difference, nice little pops and bangs on overrun like the Gen 1 used to have. I know you have a Gen 1 but Healtech will fit all models.

Might do if the price is right, but I was toying with the idea of going back to stock headers, not made my mind up yet, but in that case I'll need a new servo anyway.

I did this mod earlier this year when I first got my Gen2.  Eventually I got the Black Widow headers with the Akro HP can with a Brentune remap.

 The stock headers certainly did sound better with the flap open...no shortage of pops and bangs.   No definitive performance but I did like the fact that it was louder for the cool factor  and safety reasons.

When i did mine, I pulled the servo motor and the cables off the bike.  I had also read that you should safety wire it open to prevent it from ever closing due to a bad spring or high pressure that could cause it to close.

And the benefits of all this are.....? Does it just make the exhaust louder at a certain rev range but no difference to performance?🤔

Why is it more likely to burn the servomotor out than when cable-connected?

There's no feedback switches in the valve are there?  I must have a look.

I'm no electrical expert but from what I've noticed high torque servos like the one in the exhaust valve tend to rattle themselves apart if there is no physical resistance on them to "pull things taut" When I took mine off it had something loose inside and the output shaft had rather large play in it.

Ah-hah!   Interesting.
