MotoCreations Boom Tubes exhaust for the S4RS

[He Man]

It's what let my bike run without detonating...

Howd the PCIII install go? Just plug and play?

[NAKID]

Pretty much. Only issue I has was the software wouldn't communicate with the PCIII with just battery power, even with the engine running. I had to use the 9V adapter. It even worked OK with the map from my S2R800 loaded on there. That one had straight pipes and was a custom map made on a dyno. But I decided to go with one designed for the DS1000....

dude, try to get a video up on youtube or something.  i'm going to do that once i get my bike back...  i'm curious myself to hear the sound on a drive by.

[NAKID]

Hopefully the wife can shoot one tomorrow....

custom DS1000map?

I got some pipes to make my own "boom tubes" and if your plug bike pluged and played i dont know why mine wouldnt. We both have 06 S2R1ks.

I just want to make sure,

O2 unplugged, S2R800 or really any PCIII with the right wire harness, plug in, load map, no problems with the ECU and PCIII....

[NAKID]

The PCIII's for Ducs are pretty much all the same with the exception of the map preloaded on them.

My PCIII was "technically" for a 800SSie. There was no specific PCIII for an S2R when I got mine.

I have the O2 completely removed , vented airbox, and BoomTubes. The PCIII goes on exactly as it did on the 800. Connects to the orange wire of the TPS.

The real test will be tomorrow when I take it for a ride...

Sound clips
1st one:  It appears the tabs holding the pipes together snapped. The fwd cyl shakes around a bit. The production pipes will have a crossover and this won't be a problem.



2nd one:  Just after startup, pulling away, closing throttle clip ends with me about 1000 ft away.

[He Man]

oh my lord! that second clip sounds like you ran over a bunch of kids traped underneath a fence and draged their bodies all the way. That is the engine braking noise right? cause it sounds make the beast with two backsin insane.

those pipes sound make the beast with two backsing MEAN though. i assume they are basically open headers since you removed the baffels. It doenst seem like there are any problems running without cross overs either.

 

[NAKID]

It runs great, I need to change some parameters in the map down low, it's too rich.

The crossover should help with scavenging and smooth out the sound a bit...

[rosstermyer]

 

i cant wait till this comes out for the 696.

[Murdered Monster]

No Sh*t!! That sound bad ass! I can't wait.

A couple of notes:

1) BoomTubes had a slight delay in manufacturing via my vendor.  Corrected and we are back on course again.  Updates for the 4V guys in a few weeks in regard to ordering with 2V'ers shortly thereafter.

2) Chris/Nakid's system is the older style BoomTubes I did.  Yes -- there have been different flavors as I went along.  37+ handmade systems have allowed myself to do some tuning / experimentation along the way.  Newer systems have a more gentle "overrun / off throttle" response.

3) Nakid's system is now "wide open".  No restrictions or baffles in them at all.  Even in this configuration, they are tolerable at low/mid rpm.  WOT -- it sounds like you are riding the chariot into the Roman Coliseum with the crowd getting excited.

4) Chris just tried a new fuel map I created for the PCIII and that I've dyno tested on a few other bikes.  It's a bit rich down low still, but we will correct via the dyno once the production 2V S2R1000 systems are in production.  As for horsepower with BoomTubes and the PCIII mapped properly -- he can answer that one for you himself.

5) Due to the wait due to the manufacturing vendor, we have done more experimentation on baffling options.  I think we might have found a nice quiet one that isn't very restrictive at all.

Thanks for the patience everyone!

I. Can't. Wait.

Just looking at my bike, i can't picture where the pipes will exit without hitting my swingarm... 

With the pipes coming out at an angle (as i believe i read they would on the production run) have you thought about an angled cut pipe? (or would that funkify the baffles)  I just think it would look sweet.

[NAKID]

The map Mark sent me was a great start. It was not designed for the 2V, so there are some differences, namely low rpm/low throttle input. That is trial and error for now with Dyno Jet's software as I don't have access to a dyno. It is a bit rich down there. After about 3-3500 rpm, it pulls like nothing has before! It has so much more pull everywhere else in the RPM range.

Thanks for the vid, made up my mind 

Hope a neighbor doesn't come over and kick the bike over if you ride home late one night.
