Valves, guides, seals, valve job, not to mention the piston and rings.
Measuring clearances upon inspection is one way to ascertain the lifespan of parts, but in a spinner motor like the wr the life span is also duty cycle. Also make sure to remove your piston and inspect your small end.
If you cane your bike you will want a little peace of mind, no?
These things will break if you try hard enough, the top end inspection just costs gaskets and an afternoon of your time.
