Heard many different ways on breaking in a new engine but what is the right way ? Im so confused lol

 

Make sure it's got oil and drive it like you stole it. If it breaks, it's under warranty. Harley's are hard to break. Enjoy your bike!
My 103:

 

search for it brother, there's 1.345234 million opinions on here

mine is the same as above - keep the fluids topped off and ride it like you normally would.

 

You'll get a lot of opinions here but why not follow what the owner's manual says?

 

I highly recommend you check out this excellent article on the subject.

Well a 103 is much more sensitive to proper break in procedures than a 96" or an 88". Too much info to go into here, but make sure you're using the 103" oil!

 

There was a thread on this last week and someone posted a good article on break-in. Some basic facts that most agree on are:

-The rings are broken-in in the first 30 to 50 miles.
-Rings need a fair amount of cylinder pressure to seat well.
-Make sure you warm up your engine to normal temp before you start your break in proceedure AND don't let the engine overheat. Stop and let it cool down.
-The rest of the engine break-in can take up to 3000 to 5000 miles.
-Vary your RPM until 500 miles, meaning don't cruise at one RPM more than a couple minutes.
-Don't lug the engine.
-Standard Oil (non synthetic) is better for break-ins.

Those are facts that most folks agree, give or take. Now how you break-in with in those facts is where folks disagree. Here is one break in that is more agressive than many here are comfortable with.

I agree with Beary

Do what he said. Get the oil changed at 1000 miles and then ride like you want.

 

I broke in my Street Glide almost like the book said. Get a fair amount of blow by.

I broke in my Street Bob like beary's post. Hardly any blow by.

My 106" will be broken in on the dyno.

The Mototune method is the way to go.
