i got a honda 400ex and its tough to roll it when i pull in the clutch (when its off). My buddies 400ex rolls smoothly when i pull in his clutch and roll it. when my 400 is on and im riding my clutch seems fine like nothings wrong. shifts just fine. Is it time for a new clutch or is it suppost to be tough to roll when i pull in my clutch while the quads in gear? thanks for the help guys. -riley
