What are the signs of 2nd gear going bad? My bike a 99 R1 when accelerating hard in 2nd it will act like the chain is jumping teeth but it is plenty tight. It will make a popping noise and you can feel a jerk. I am afraid this is the common 2nd gear problem. Any ideas and help is appreciated. Also I am new to these bikes so try to keep it half way simple or explain well. Thanks Guys.
