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!

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

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.

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.
