I previously had issues with my bike it was sticky and jerky so i thought it could be the clutch. After replacing the friction plates and springs my jerky issue did not go away. After replacing my chain and sprockets it fixed it. Now when i go hard on the throttle in first and second gear at peak power it seems to hesitate and slip until i roll off then back on or shift gears. The problem isworse some days than others. Any thoughts?
