I HAVE RECENTLY PURCHASED A 1999 ZX-9R, WITH ABOUT 10,000 MILES. THE ONLY MODIFICATION I KNOW OF IS A MUZZY TITANIUM EXHAUST. WHEN I TAKE OF ON THE BIKE IT STARTS OFF FINE, THEN IT SPUTTERS A LITTLE, THEN IT WILL TAKE OF FINE. THE ONLY TIME IT DOES THIS AT LOW RPM'S. AFTER THE BIKE IS UP IN THE RPM'S THE PROBLEM GOES AWAY. ANY HELP I CAN GET ON THIS PROBLEM WILL BE GREATLY APRECIATED. THANKS IN ADVANCE FOR ANY IDEAS YOU MAY HAVE.
