Checking Oil Pump Gear Drive...

• Drain oil tank.
  
  
• Remove the clamp that holds the shock accumulator. Do NOT remove the accumulator oilline ever!!!!!!
  
  
• Remove the oil feed hose.
  
  
• Remove the oil filter hose. Make sure to loosen pressure on the hose before loosening completely.
  
  
• Remove the return hose, if possible. If the hose is long enough, its not absolutely neccessary!
  
  
• Carefully remove the two mounting screws (allen NOT torx)... pump will drop with the screws removed, so be careful! Now you can remove the return line anyway.
  
  
• Store the oil pump in a clean place, remember it's the heart of the machine!!!!
  
  
• If you place the motorcycle against a wall or support it safely to let it lean over the left hand side, you can look in the oil pump hole.
  
  
• Now you can check the gear with a flashlight, rotate the engine by putting it in gear (engine not running of course) and riding it slowly back or forward.
  
  
• If you see ANY signs of wear have it replaced. And then also examine the oil pump. Do not gamble with this, if you want to keep enjoying your bike for awhile!
  
  
• If you're absolutely sure that there are no signs of wear assemble the pump again and liberally coat all moving parts in the pump with engine oil and install the pump with a new gasket.
  
  
• Connect the hoses again (make sure they are clean), fill tank with fresh oil.
