2000 Yamaha waverunner xl 1200 / blocking off oil pump

[cocacola321]

Can anyone walk me thru blocking off the oil pump on a 2000 Yamaha waverunner xl 1200 so I can run pre mix? I have the exhaust off cause I had to replace the #2 pistion and wont to do this before I put it back together.

Thanks,
Steve
