Hey guys I’m new on here ... I have a 2002 Honda 400ex I’m workin on for my buddy... it has k&n air filter and a excellerater exhaust by DG performance... it idled fine but as soon as you got into it it would cut out .. unless you turned the choke bout half on then it would run pretty good .. I need a starting point for the carb .. jet size and needle position?

I think a good carburetor cleaning is needed and strongly recommend a OEM rebuild kit. I would check the petcock, and all valves within the carburetor, i.e., needle, float, etc.
