Description

Mike Roen has built up a lot of Milwaukee Eight engines since their inception in 2017. He has an enormous amount of experience with, not only building these Milwaukee Eight engines, but with diagnosing and repairing this Harley-Davidson engine.

In this video, Mike takes a little time to explain the differences between the Milwaukee Eight engines that are factory built as well as the differences between Screamin Eagle and big bore motor kits. If you are considering increasing your Milwaukee Eight engine displacement, it is of utmost importance that you spend the time to do some research. Make a plan that works with your budget. Make an educated plan so that you will be utilizing parts that work together optimally. Don’t just shoot for a kit that gives you the biggest displacement number. Bigger is not always necessarily better.

It is important to consider:
Displacement – what size motor or what kit will you be using?
Cam – what profile cam will be used?
Throttle body – will you be using the stock throttle body/induction module and injectors. Or will you be using something larger and with performance injectors?
Air intake – what style air cleaner assembly will be used?
Exhaust – what will the exhaust system be?
Tuner – it is important to note that most tuning centers prefer working with DynoJet Power Commander or Power Vision tuners.
Oil pump – regardless of what combination of parts are to be used, a performance oil pump is necessary.

Below is the information right from Mike’s list in the video. The information is an important reference when educating yourself on the differences between Harley Davidson Milwaukee Eight engines and big bore kits.
