  RPM at 6000 is beri smooth riding but bikes with valve must ram to high RPM if not long time no open valve ... the valve will jam ...

  my opinion is that whatever rpm you are in, do not drag the engine.

  what is the reason for the valve being stuck?
  
  is there any preventive measures that we could use?

  Hi there,
  
  I was concerned about this too. So I searched the web and found this article at http://www.msgroup.org/TIP094.html
  Pretty good reading as it allows one to build a gearing chart.
  
  And I think your SP has a valve.
