bogging over bumps

[T-were]

my 400ex is bogging down when am wide open or close to it when going over rough terain, like it isnt getting gas, it is stock with the spark arester removed from the silence, and just started doing it a few days ago, if i say on the gas it keeps bogging but if i let of for a sec. and get back on it goes like a raped ape(like normal) any idea?

ever try putting your end cap back on?

put your spark arrestor back in and buy a new pipe then rejet and see if it still happens
