2021 KX250: Installing a New Chain and Sprockets

Here's the complete procedure for installing an X-ring or O-ring chain and front and rear sprockets on a 2021 KX250. This procedure will be very similar on most modern dirt bikes.
Note: The chain used in this video comes pre-waxed. If your new chain does not come pre-lubed, remember to use the recommended lubricant or wax. Also, some of the steps provided in this video can be done in a different order. This is the order that works best for me based on the tools I'm using and the fact that I'm doing the project all by myself.

You have the axle backwards. Nut should be on the brake side

[@rhyswatson9976]

If you look towards the end of the video he also doesn’t equally adjust the chain adjusters and the brake side is nearly 1.5 lines less than the chain side. This means he’s wheels is going to be wonky asf
