i have 09 fz6 10,000 miles. i just changed my plugs ngk/cr9ek. and replaced my airfilter with a K&N factory replacement. and now my bike which WAS running fine seems to be hesitating on takeoffs in first and when switching into second gear. so i checked airfilter again for proper install. check, looked at plug wire sequence.check. and i have to say im a little dumb founded! im considering putting the factory airfilter back on. i would appreciate any input, or has anyone experienced this with an aftermarket airfilter?
