blaster bogs in 6th gear?

[05blasterkid]

i have an 05 blaster that was stock and never bogged out in 6th gear. Then i put a k&n air filter, boysen reeds, and a dg exhaust yes i know it sucks, and i am running a 250 main jet. What could be the reason for this? should i go higher in my jetting?

do a plug chop and see what color the plug is. you might actually be too rich
