I have a guy who sunk a 94 Yamaha VXR Pro. I got it running, he took it out for acouple hours, runs great, but smokes like crazy. I cleaned out the oil tank, replaced it with YamaLube oil, same as what he was using. The oil pump is mechanical, not sure if there is an adjustment on it or not. I did run plenty of oil through it when I got it started, but after 10 minutes on the water that should be out of there. He wants me to look at it again, but not sure I can help him. Can this pump over-oil? Thanks, Bruce
