I found a Sportster engine for sale. What are the first things I should check or replace?

When starting with a used engine of unknown history, it's wise to at least perform a top-end refresh. This typically includes new gaskets, checking cylinder and piston tolerances, and inspecting the valve train. This gives you peace of mind and a reliable starting point.

What are the easiest ways to get more power from my stock Sportster engine?

The most common and effective "Stage 1" upgrades are improving airflow. This means installing a high-flow air cleaner and a less restrictive exhaust system. These two changes allow the engine to breathe more freely and will deliver a noticeable performance gain without ever opening up the motor itself.

I'm rebuilding my engine. How important is it to replace all the hardware?

While not always strictly necessary, it's highly recommended. Engine hardware is subject to countless heat cycles and stress, which can cause it to stretch and weaken over time. Using new, high-quality head bolts, case bolts, and other hardware ensures proper torque specs and a leak-free, reliable engine for years to come.
