2014 HUSQVARNA TR650 Power Train Problems

MOST SERIOUS ISSUES ARE THAT THE ENGINE HESITATES ON ACCELERATION AND STALLS WHILE MOVING IF I ATTEMPT TO DOWNSHIFT IN ORDER TO DECELERATE IN A CONTROLLED MANNER. THE HESITATION BEGAN AROUND THE TIME MY ODOMETER REACHED 2000 MILES; THE STALLING BEGAN AFTER THE ODOMETER REACHED APPROX 3500. REGARDLESS MY SPEED, FAST OR SLOW, THE BIKE STALLED AFTER I PULLED THE CLUTCH IN AND DOWNSHIFTED, ALSO REGARDLESS HOW QUICKLY I RELEASED THE CLUTCH OR ROLLED ON THE THROTTLE. IT HAS HAPPENED TO ME > 20 TIMES (NO EXAGGERATION) IN 300 MILES OF RIDING THROUGH TOWNS AND ON HIGHWAYS, WHENEVER I WAS SLOWING DOWN. ADDITIONALLY, WHILE RIDING SLOWLY OFF ROAD IN 1ST OR 2ND GEAR, THE BIKE WILL HESITATE OR STALL UNLESS I HAVE THE RPMS TO >3500. HAZARD TRIANGLE AND EWS LIGHTS THEN COME ON AND I HAVE FOUND THAT IF I TURN THE KEY TO OFF THEN BACK TO ON,...
