When I had my motorcycle, I bought a set of 9 DVDs that explained a lot of maintenance tasks (including things like valve adjustments!) It was extremely helpful to be able to see the work being done on the exact same motorcycle that I owned.
Fast forward and now pretty much anything you need is on YouTube. I have a playlist of common vehicle things that I need to do, but I was very happy to recently stumble on the TRQ app. You punch in the details about your vehicle and then you get a curated list of videos specifically for your vehicle. It saves time clicking around trying to find the right answer, but of course it helps if you have a common vehicle. My F150 has over 90 videos!
I’m sure there are a lot more apps like this. If you have a favorite, please let me know. Thankfully I haven’t had to do much beyond basic maintenance but I’m sure that time will come.
