So I had a 95" build done on the Road King after being diagnosed with piston slap at 30,000 miles(excessive noise in rear cylinder) Keith Black forged pistons, heads cleaned up and a remap of the PCIII. After 1500 miles she loosened up and runs better than ever, a real rocket. Could not be happier, find myself in the throttle alot more now. Alot of fun. I know very mild build but the increase in power and ridability is very noticeable. Just thought I would share.
