After living in 2 different states, and being around HD's and the people who own them for the last 40 years, I know a lot of riders, several who have had motor problems (mostly 110") in the last 5 years. Those with ESP's and modifications done to the engine such as cams and lifters had no problem getting coverage for bore/piston issues, valve guide/valve seal failure etc. If it was so prevalent here and on the other boards, and word of mouth many including myself would have passed on the ESP's. The local dealer where I currently reside is well aware of the aftermarket fixes that make these bikes more reliable and less of headache for them, and appreciate the added money spent after the purchase, and have no problem honoring the ESP.
