Fireshine: Does your shifting problem occur when the bike is Hot or cold? Do you recall the last time you had the clutch fluid changed? I ask because what you describe could be a symptom of bad clutch fluid. If you invest 30mins of time and $5-$7 you may resolve your issue by changing the fluid using Valvoline Full Synthetic DOT 3 and 4 Brake Fluid (32 oz.)Part # 601458. Good Luck Rider!
