Jetting specifics

[Dballard87]

I have an 87 warrior I am running stock jets I cut the middle out of the lid for the airbox just so I have the outside of it to hold my air filter in place. If I have a stock exhaust with the baffle removed the airbox lid cut out and a k&n air filter what die jets do I need to buy?

Maybe a 147.5 main but you'll need to read the plug to tell for sure.
