I went to the Harley dealer in Santa Maria CA yesterday to trade in my 2012 FLTRX. Wow!! $38K for a Road Glide Limited. So now I'm looking to upgrade my 2012 that has 70,000 miles. I'm a highly capable A&P mechanic. I want to pull the motor, tear it down and do a killer build. I would like to go with 107 cylinders, high compression pistons, a hefty set of cams (maybe geared), heads, bigger throttle body. If anyone has any suggestions I would appreciate it.
