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?

It serves as a temporary seal for the rings.
Ah clever. Thanks for explaining.

How much oil exactly would u put in? And how would you get it out if you decide you don't need to rebuild top end? Or would it be fine to leave it in there
Usually a few ml. And it will burn out first time you start it. May smoke a bit blue for a few seconds.
