What is your reason for even having a PCIII?
I've had it on since I think November of 2008. Installed with slip on, flies, and BMC. Really woke up the beast!
I've seen many biks not start w PC's in them, mostly older. My friend had one in his Suzuki and the connectors used to get wet, seems they didn't seal aas well as OEM. Might be worth a look.
