In this video I walk through how I change the air filter on my 2022+ Yamaha YZ250, and honestly it’s one of the easiest maintenance jobs you can do that pays off huge. I start by popping the seat off, pulling the old filter, and making sure I’m not letting any dirt fall where it shouldn’t. The big takeaway: a clean, properly installed filter is cheap insurance for your top end. After the filter is out, I spend time cleaning and re-greasing the air boot rim. That sealing surface matters—if it’s dirty or dry, you’re basically inviting dust into the motor. Then I show installing a fresh filter and doing a quick clean inside the air boot area so everything is ready to go back together. I also talk about how I keep track of maintenance with a simple spreadsheet, because staying consistent is what keeps a bike reliable. If you’re new to wrenching, this is a great first job. If you’ve been riding forever, it’s still a good reminder to slow down, clean the sealing surfaces, and keep notes so you’re not guessing when you last did it.
