My First WR250R Dirt Bike - What Should I Upgrade?

Hello, I just bought my first used dirt bike.  What should I upgrade and fix?  It's a 2015 WR250R and I appreciate any suggestions on upgrades and parts.  I will do videos of all of the upgrades.  All tips and comments are very much appreciated!  This looks like a fantastic forum and I will definitely do my research here as well.

I created a walkaround video of the bike on youtube explaining everything (it won't let me post link, You can search my channel under Tim Armbruster), and also have a list below.

- Washing Dirt Bike - Products to help, brushes, cleaners, exhaust plug, etc.
