The Twin Cam is an inherently-flawed engine design.
Here we are, another completely inaccurate post from someone who does not own a Harley, never has and has no knowledge of certain models. Makes a blanket statement like its fact, yet completely incorrect.
1. No matter what engine, no matter if its a motorcycle, car, truck. There will be a certain percentage that fail. Once again, Consumer Reports reports, major failures are even among brands of bikes. So any type of timing failure on any brand could lead to problems. Happens all the time, lets say on timing belts. A certain percentage of engines will fail as we as humans are not perfect and the cost of producing a perfect product would be impossible for people to buy.
2. IT IS IMPOSSIBLE for "an oil system to get full of nylon bits" on any late model Harley touring bike. Unlike metric bikes which share the Primary oil, Transmission oil and Engine oil all together as one.
Harley twin cams touring bikes DO NOT, this is obviously a superior design, just like a modern automobile or truck and not like an outdated metric bike.
Harley has separate engine oil, separate primary oil/fluid and separate transmission oil/fluid sumps just like any modern day automobile or truck. I think we can all agree Harley has a better system with separate sumps, I bet more costly to manufacture too.
It's quite clear from this record breaking thread, how someone can read through it and learn to do their own research and not base buying decisions based on nothing but hearsay.
Just to be absolutely clear: are you, then, claiming that the cam chains are NOT oiled by the engine oil?
