400ex Jetting?

[FBRacing76]

Hey guys, My 400ex runs alright but it dont seem like it hits hard enough like it should. Im running a 175 and I have Curtis Sparks Shorty, Aluminum Airbox with Vented Lid, Web Cam, K&N Filter and I live in Ohio. Does that jetting sound right? Guys please help me! Thanks!

What are the symptoms? Does it bog down when you punch the gas? Does it pop on decleration?

[FBRacing76]

it pops when you let off at mid level rpm's but thats all

If you have not, you might want to raise your needle a notch. Pop on decel is normally due to a lean condition.

Does it accel from a stop ok? Is the problem happening just when you come out of a corner and only in 3rd gear?

It starts ok just doesnt hit like it should it blows a little bit of brown smoke that i didnt notice before.
