I'm getting mixed messages from web & HD techs.

New V-ROD NRS--what effect will removing stock muffler cans have whilst awaiting upgrade?
- Riding style is moderate-to-aggressive
- everyday rider (10-15mi); with a planned 200mi trip coming up this weekend.
- All stock (no air filter/intake changes/tunes/etc)

I've read/heard anything from
- low miles; little-to-no-negative-effect provided air intake isn't increased
- could likely alter fuel:air ratio and/or O2s...after a "long while" without cans
- Bike blows up, killing a small village in rural Idaho.

First HD; crossed over from rice burner, yes, "sound" is the why:

1. what are the technical outcomes/risks of this weekend's 200mi ride without cans?
2. Or don't sweat it but make it a priority to get proper backpressure/exhaust/A/C & ECM flashed before 500mi on bike?

(Any technical insights are greatly appreciated in advance.)

Just running headpipes with no mufflers at all? Bad idea! Taking a hole saw to the factory muffler and knocking the blocker plates out (will need an extension to get both plates), and gutting out the Cats from the head pipes, that would be OK.

 

Air gets in reaching O2 sensors. They send "lean" signal to ECM. ECM increases fuel. If you ride w/o mufflers, check spark plugs color.

 

Great first post. Welcome to the Forum

 

No cans will decreased back pressure causing backfiring... among a plethora of other issues.

Welcome to the HD/cruiser world. I've ridden all kinds of bikes: old UJM's from the 60's-80's, japanese V-twins, sport bikes (R6, FZ-6, 600RR), and my HDs. I think you'll enjoy the HD experience.

Almost everyone I knew that got a VRod as their HD gateway drug changed out within a few years to a bike with more traditional stance (rake/trail angle) as it was more comfortable and easier to steer. Don't get me wrong, the VRod's look fun, but you might just get hooked on a Dyna or a softail. My drug is currently an Electra Glide (Evo) and a Road Glide.
