ENGINE IS STALLING FROM UNKNOWN CAUSE. ONLY CONSISTENT CONDITION IS THAT IT HAS OCCURRED DURING SOME FORM OF BRAKING AND ONCE CLUTCH IS DISENGAGED. OCCURS AT ALL SPEEDS. MOTORCYCLE WAS BOUGHT BRAND NEW AND STALLING OCCURRED IMMEDIATELY AFTER LEAVING DEALERSHIP. STALLING IS INTERMITTENT, BUT FREQUENCY OF OCCURRENCE HAS INCREASED. STALLING OCCURS WHILE IN MOTION. STALLING HAS OCCURRED FROM 3-65 MPH. STALLING HAS OCCURRED WHILE BIKE IS MOVING UPRIGHT AND STRAIGHT. STALLING HAS ALSO OCCURRED WHILE BIKE HAS BEEN LEANED OVER AND TURNING. IN ADDITION, DISENGAGING THE CLUTCH CAUSES A FLUCTUATION IN RPM DEPENDING ON CLUTCH LEVER POSITION. WITH ABSOLUTELY NO THROTTLE INPUT AND WITH CLUTCH LEVER TOUCHING THE GRIP, TRANSMISSION IDLES AT SAME LEVEL IN GEAR AS IT DOES WHEN IN NEUTRAL (APPROXIMATELY 750). HOWEVER, ONCE LEVER MOVES A MERE ⅛ INCH FROM GRIP, THE RPMS INCREASE BY APPROXIMATELY 500 RPM. THIS OCCURS WHEN LEVER STILL HAS AT LEAST ANOTHER 1 INCH OF TRAVEL TO GO UNTIL FRICTION ZONE (ENGAGEMENT). THIS CONDITION IS ALWAYS PRESENT.
