Hey guys this is my first post so bear with me. I have a 2001 busa and it has been making a flapping/rapid clicking noise only under load. We thought it was a cam chain tensioner since the 2001's seemed to have problems with it. But when we looked at the tensioner it has an oil line going to it which means it isnt really a 2001 motor :/. So we think it could be valve issues. Any thoughts on what the problem could be?
