Pilot Jet

[GP400]

Does anyone use a 50 pilot on a stock 400EX engine? Procircuit recommended a 155 & 55 for the full system. I thought the pilot was too big and used a 50 with a twin air and EHS racing airbox lid. I think it's still too big. What do you guys recommend?

i would go down to a 42 or 45.
