So I have a 400ex stock beside k&n filter with lid on and full white brothers exhaust. I got the quad like this 5 years ago. Today I took the carb apart to clean it and seen that my main jet is 155 and pilot 38 these seem way too small? Iam at 1000 elevation but ride the sand dunes which is at 400. I seen the post by Josh on here. I plan to remove the air lid now also now. I’m thinking of going to a 165 main and 4 pilot jet what do you think?
