Im rebuilding the carbs on a 1998 yamaha GP800. What is the pop off pressure supposed to be set at. The ski has a hard start when cold problem, and upon opening the first carb, the needle was stuck pretty good in the seat. I am ordering new gasket sets and needles/seats. I checked the first carb twice and the pop off pressure was 80psi. The needle tips are grooved pretty bad, so I was wondering if that would contribute to a high pop off pressure reading.
Anyway, after I install the new needles and seats and take a pop off pressure test, I was wondering what they should be at.
