900 oil line check valves
On a 02' 900 STS i picked up, the oil lines have check valves between the pump and carbs, but the parts diagram does not show them.
Was this a dealer installed TSB? I know the yamahas have them, just never noticed them on a kawi.

I don't have a 900, but my 750s, 1100, and Ultra 150 do not have them. The oil tank isn't much higher than the carbs, so they really aren't needed.
