I just bought the bike and the seller rode it to my residence just fine. Now when I start the bike and shift from neutral into first gear, the bike lurches forward with the clutch completely depressed and disengaged. This leads me to believe that the engagement point is extremely early (deduced from online articles) or that there was air in the line. I just finished replacing the fluid and bleeding the line and I found the fluid to be a gunky yellow/green so I suspected the problem was solved, no air, new fluid, no problem. I started the bike up again and found no change in the problem. The bike still lurches when switched into gear. Also, when off and in gear, the bike will not move freely with the clutch completely depressed. I am new to riding and seek to repair my clutch to the point where it will fully disengage. Thank you!
