How-To: Rebuild a Four-Stroke – Part 2

2 months ago

Where the bloody hell do you start when it comes to rebuilding a four-stroke engine?! It ain’t quite as easy as rebuilding your old two-dinger but with some expert advice and help along the way from your bike’s service manual, it is possible for you to do from home.

Luckily for all of us, ProX Racing, have created the perfect video tutorial series. They purchased a well-used 2015 CRF450X engine and have taken on the job of teaching you how to completely teardown and rebuild it.

In parts 7 and 8 of this 12-part series, ProX Racing dive into assembling the crankshaft, PTO side gears, and cases.
