I would consider it critical at least to a certain extent. I would think any newly acquired EX
should have a valve check done right away, because you don't know when the last one was done. Given the mileage on your bike, even more so for you.
Some symptoms of out of spec valves:
Hard to start
A stumbling idle
hearing a loud enough valve ticking sound
I'm sure there are more also.
I don't know where you are located. You may be running out of a riding season shortly. Advise to do it as soon as you can. Maintenance schedule calls for this every 7,500 miles. It has been reported several times that valve lash has fallen completely out of spec (sometimes by a large margin) within the 7,500 interval.
Tools required are all just basic tools. You probably already have what is needed. I would just have some replacement O-rings for the water pipes and oil pipes on hand before starting.
