Thanks Gefr. I was able to slide a hair through it, so I guess it's ok. Geez thats a small hole. It was clogged.
QUOTE=gefr]The hair thick jet hole is 0.30mm diameter and is really thin. The oil pressure though is high enough to deliver enough oil to the clutch! You could test it connecting it to an elastic hose and pressuring some water from the tab. It is difficult for the light to pass even if some oil is in the hole.[/QUOTE]
