I have a 2012 r6 with almost 13k miles. I let one of my buddies take it for a spin and well needless to say it came back with a horrible noise in 2nd gear. My question is that its only in second gear. knowing that when in neutral it makes a clunking noise but when pulling clutch in noise gets quite. Any suggestions on what to look for. Sprockets look good so does chain. No clutch slipping nothing just noise. I rode it to work and no power difference just bypassed second gear and straight for third no issues in any other gear. Reply's would be great since this is my daily driver.
