Common issues on wr250r?

What are the common issues to check before buying a used wr?

Pretty bullet proof, there was a stator recall around 14'-15' other than that rebuilding the forks is all I have done other than routine maintenance @ 13K miles. Main thing is if it had care, oil changes, air cleaner etc.

some had fuel pump issues, think it was older models though

I'm new, but here is what I've read/experienced:

1. Auto cam chain can be an issue
2. Swing arm grinding and the 13 tooth counter sprocket
3. Lack of power due to smog stuff
4. Fuel pump overheating/failing
5. Stator overheating recall
6. Soft rims
7. Heavy
8. Lack of specific parts

These are small things in my opinion.
