Ttt!! We got this 450 and it's got a yoush slip on and k and n filter. I'm noticing it's bogging at 3/4 to full throttle when the clutch is disengaged just coasting, or in N. It hesitates for a brief moment then catches after the delay. Never rejected a carb before, but I did some reading. Thinking it needs a bigger main jet. What do you guys think? Also the dude I bought it off of said he never rejetted it after the mods.
