I picked up a 2003 FLHR Road King today that I won unseen in auction last week. It's very tidy and runs well and comes with a screen, Panniers, rack and passenger back rest. Mileage is 13k and it looks like it's running the original drive belt. Doing a quick web search it seems the cam tensioner is the Achilles heel on the 1450 twin cam engine. Do I wait for a few more thousand miles before sorting the tensioner (I believe Harley recommend changing it every 30k) or should it be sorted now as the machine is 17 years old. Same with the drive belt really, can it be left as the mileage is low or should it be changed? The last owner also fitted an American brand reusable oil filter, are these safe to keep cleaning and reusing? I plan on hanging on to the bike for a while: is there any preventive maintenance recommended for this 2003 model. I am not that knowledgably about Harleys but I did own a Evo Electra Glide for a couple of years and I get Harleys. Thanks in advance
