Someone please help,
I just bought a used 400ex and it runs perfectly, but like many 400s, cold starting gets confusing. I decided to play with the air adjustment screw(idle set), and found that it was screwed in all the way, I still dont understand how the bike runs perfect when its warm with it in all the way. To get to the point I unscreded it out 1.5-2 turns and noticed that the carb overflow was letting gas flow out at max. pace. Could someone please tell me how to fix this, thanks.
p.s.:only mod is a new fmf powercore 4 exhaust.
