Aircraft
During taxi; ATC cleared us to taxi to Runway 31 for an intersection departure; it was noted that max thrust was necessary because of a small tailwind. During the application of takeoff thrust all engine parameters appeared normal at about 100 KTS. Left engine N1 decayed to approximately 94% plus or minus 1% with fluctuations; with 'command arc' displayed to the Thrust Rating Computer limit of approximately 102% N1; no adverse yaw noted. Takeoff was then aborted at approximately 120 KTS. Inspection of main landing gear was then conducted by Airfield Rescue and Fire Fighter crew. Aircraft was then taxied to gate without further incident. Gross weight at takeoff 295;000 [LBS] O.A.T. 12c.
At about 120 KTS on the takeoff roll; a B767-200 left engine N1 decayed to approximately 94% so the Captain rejected the takeoff and had the main gear inspected prior to proceeding to the gate.
