Simply not true....at the least, its VERY misleading how it was said above.
A reduction in backpressure will lean out the engine a LITTLE...but its a MUCH bigger issue on Vtwins (that NEED more backpressure) than I4s.
The FZ6 exhaust is about 5 feet of tubing, containing multiple bends and TWO catalytic converters (on the 07+ models anyway).
Changing out the muffler, hell....REMOVING the muffler is NOT going to cause the engine to lean out to any measurable degree on this bike.
