    Xl800 oil injection

    I recently finished top end rebuild on an XL800 Yamaha. I have run about 70 gallons of premix fuel. That's 300oz of oil. I wanted to use the oil injection. I did the new lines and check valves and can see the oil in the lines. the thing is I only have added about 60oz of oil to the oil tank. I did the alignment of the throttle and pump per service manual. Is this correct? Am I going to use less oil with oil injection or is the injection pump bad. It took several hours of use before the lines filled. I don't mind mixing gas but if oil injection uses less oil I may consider buying a new pump.

    Yes, it uses alot less oil with injector pump, (around 100 to one at idle)..I tend to put a ounce per gallon in the tank also.Keeps carbs corrosion free and will limp home if it ever stops smoking like a GOOD two stoke in salt water.
