My 2000 883C had a bad noise in the engine. Diagnosed it to be a bad lifter. I took the rear cylinder head off and got down to the lifters and you could clearly see the exhaust lifter had collapsed. I have it out. Now my question is, can I just change that one, or do I have to do all of them. I know I have to replace a lot of gaskets and O-rings and so far just to replace the one and the gaskets it's not as expensive as I thought. Through one of the more popular parts company (Don't want to violate any advertising rules, but there's one next door to the big Harley dealer in Daytona) it's only a couple hundred bucks.
