I am looking at installing Gear Drive cams in my 2010 Road King. I know that a tech must first measure the runout of the crank to determine how straight it is. My 2 questions: 1. If the tolerance is too great - can the chain drive cam be installed without issue anyway? 2. If the tolerance is over the allowable for the gear drive set-up - what is involved in correcting it and at what cost? Thanks in advance.
