I have a knock in the front of the primary at idle so I took it apart and I noticed today that the cam is sliding 1/2 to 3/4 up the ramps.(looking at the wear) I thought maybe the bolt was coming loose but it was a bear to get off. This bike has a 113 S&S motor, I have read a few threads and believe it is probably the spring has gone bad. I can replace it with a new one but was wondering if there are any other options out there? I saw somewhere a setup that got rid of the spring and the ramps, has anyone tried one of these? Is there any real reason to have the ramps and spring in there?

Thanks,
