I can't say for sure which parts on your carb are bad. Problem could be caused by something else as well. What I would do would be tear the carb off and check the accelerator pump out. It might just need the diaphragm, but you won't know until you look at it. Also inspect your main diaphragm (#8) for any cracks.

I'll do that, thanks again!!

You're probably needing part #32 on this diagram.

Do I need all parts associated with that diaphragm or just the diaphragm assembly #32 in the picture?

Sounds like   the accelerator  pump isn't working properly. 

Can you give me more details on this, where it's located, what it does and where I can get it? Also how difficult to replace? Thanks.

I have a 04 LTZ 400 I just picked up. It's completely stock as far as I know besides an upgraded k&n style air filter. I recently flushed all the fluids and cleaned the carb out as well as replacing the main jet o ring that was corroded and replaced the spark plug. The issue I'm having is that the bike starts right up and idles perfect and revs fine at any rpm when u hit the throttle but as soon as it's warm, if you hit the throttle quickly it will bog and sometimes die. If you gradually increase the throttle at a smooth rate it revs fine. What could be the issue?
