i have a well ridden gt5 with about 700 miles and havent ridden it in about a few weeks,ran great when i put it up,well started it ran great let it warm up went thru town and opened it up like normal,and when i let off the throttle,i was high revving,checked for leaks none,checked for throttle sticking works fine,but while it revving i can jump the clutch and slow the idle,and pull the clutch back in and it will idle fine rev it up and same thing,it use to have a very crisp throttle?any thoughts would help
