Ok guys first off I'm new here.I just recently got a 2001 Honda 400ex and I am having problems with the carb settings and jetting.I have grow up working on cars for a living and fairly decent with ATVs.I bought the quad with a bad motor and it was all stock so let me start from the beginning.The quad now has a wiseco 11:1 86mm piston,hot cams stage 2 cam,ported head,k&n filter,fresh top end,performance coil,11,000 rpm rev box and a pro circuit t4s full exhaust.The quad is broke in now but is topping out at around 8,700rpm and 66mph.Bottom end is great tho.I currently have a 42 pilot jet and a 178 main jet.That is just based on what the local atv repair shop told me.Please help at least get me close.
