I have a few questions if anyone can help me . I have a 2001 trx400ex I did a complete top end rebuild. Ported head 416 cylinder with new piston. Has a power bomb header with a hmf slip on a k&m filter and its jetted . And finished the heat cycle. So the issue I am having with it. When I am in the full throttle it loses all power till I let back off to half throttle then it speeds back up . It will idle fine and take off fine .just on the straight away when I open it up it bogs down .any suggestions will be highly appreciated

I'm taking the carburetor back apart and see if its clean. What main jet size would your think would help . I'll know the size I have in it right now after I take it out

Sounds like you need a bigger main jet or the main jet is plugged with dirt.
I changed the jet have a 152 in it now that fixed the fully open issue.. but now it pops on deceleration. And now it wants to die when I reve it in idle?
