i have a 2000 road king and just had the tensions replaced at 54,000 mi.
along with the cam support plate,oil pump,cams,lifters,cam bearings and push rods. the info i got fr a friend at HD is the chains are the cause of the wear on the tensioners-they were never polished to a fine machine finish-also my stock oil pump doesn't pump real great at idle or low speeds.hd has a new
hydralic tensioner setup with a new pump and cam support plate.
not having enouugh $$$ for a gear drive i settled for oem parts ,se 211 cams
fueling lifters and adj. pushrods and new chains and tensioners-i was lucky that all the bearins were still in the cam case-the wear and tear on the other parts was real sad to see as i always change the oil etc and maintain the bike
