Amen. I thought it was bad on the 90...98 was PIA+:fing02:
VFRs are an absolute cakewalk compared to a ZX-10R. On that bike, you have to remove both seats, 2/3s of the tail cowling, both side fairings, the inner fairing panels, the entire airbox assembly & ram air tubes, the PAIR system, the coolant overflow tank, and actual portions of the frame (not to mention moving the tank and radiator) just to gain access to them. On a 5th-gen you need to lift the tank and unbolt the oil cooler -- consider us very lucky.
BTW, I use NGK Iridiums in all of my supercharged applications; they're great plugs.
