Motorcycle Repair: 87 yamaha virago 700 overflow, needle valve, valve seat

Question
My viragos rear carb just poors gas into the cylinder and i have to replace the oil all the time. i have the fuel stoped for now. What are the numbers on the main jet for factory?

Answer
First off its not the main jet causing the problem.
Either your float is bad and is saturated with fuel or your needle valve and needle valve seat need replacing.
