The beauty of the PC3 is a tuner can totally dial your specific set up in.

I'm just curious as other people have stated it. But is this fact that Yamaha does indeed program the bike on the rich side so people can modify the bike? Or is this just internet legend passed on from thread to thread. I'd like to see the actual Yamaha documents saying "We purposely made the FZ6 run rich for all you tuners."
I just went and read the warranty info on the bikes, even if these internet claims that Yamaha has built into the feuling the ability to compensate for aftermarket exhaust. If your bike breaks because of it don't go crying to Yamaha.
directly from the Yamaha warranty pdf.
3. This warranty does not extend to:
a) MOTORCYCLES which have been modified
in any way from the standard specifications
as shown in the Owner's Manual, including
any MOTORCYCLE whose odometer has
been altered;
b) Use of lubricants, oils and fuel/oil mixtures
other than those recommended in the
Owner's Manual, improperly installed
accessories and use of parts or accessories
that are not equivalent in design and quality
to genuine Yamaha parts;
This is strictly from a Warranty stand point. I'd still like to see some Official Yamaha words that the stock fuel is set up for aftermarket parts.
