Too weeks ago, installed a GPR exhaust that comes with a "Y" mid pipe a few weeks ago. Put a Power Commander PC3 on the next day.
Quick summary, a lot more power at higher (4500+) rpm. The engine used to go flat at about 6000, now loves to charge up to 8000. Complete personality transformation. Feels smoother and happier. The power is reduced in the 3000-4000 range, but it was torquey enough that this was a good trade-off. Saves about 20-25 lbs.
The 4500/5000 ping is gone.
Went without the (dual!) db-killers. The sound is much nicer than stock. Still quiet until you twist the loud handle, so is a great improvement. Just the sound a stocker *should* have. The flavor of the sound is nice, but nothing special.
Would definitely recommend! Sorry I waited so long, after having the bike 6 years. It is a 2002 LeMans. Makes me certain to keep another 6 years.
Absolutely, positively need the PCIII. The one day without it, it was nasty, surging at 3000 and generally not happy. Only took minutes to install.
Just guessing, I set the PCII for +2 at low, +3 at mid, and +2 at high. Expected to be playing with it a lot, but ran great at those settings immediately, so haven't tweaked it since.
Got the PC from 58cycle and the exhaust from Moto Legends.
Has been very smooth (for a V11), except a hot day in the desert (maybe 90) when I was trolling thru town.
Cosmetically, the single-sided titanium pipe is quite pretty and takes the visual weight off the back. So much so, the bike looks better without the pillion cowl. A surprise.
Question:
Since I've assumed the pipe would lean it, and wanted to fix the freeway ping, I automatically set the PC for the settings above.
Is it possibly running too rich?
If it is too rich, how would I know? Does it matter?
