Bike stuttering badly

I've been riding for 3 months now and in the past couple days my bike has started stuttering and serious loss of power at normal riding rpms.

It is fine at idle and seems fine when i gun it but as soon as i let off a bit it stutters like crazy.

It is my daily driver and i ride rain or shine. I can't afford to have the bike down.

Does anyone have any idea what it could be? I first noticed it about a week ago when i felt it stutter once every couple minutes. It slowly has increased and now is nonstop.

I have sat and sunday to really work on it and am hoping i can get a decent diagnosis to focus on.

I know i'm probably asking a common question but i'm very desperate and need help till i get on my feet with this thing.

Does it happen when the tank is full? If not an only starts happening around half a tank then it's POOGS.

Sounds fuel related. You get more suction on the fuel when you gun it and you don't need as much fuel when at idle. I'm thinking something is clogged.

*2..

also has it been earshaved??? would double check the carb vent lines regardless. they have been know to kink or otherwise obstructed (if not shaved, check the vent line in right ear (air filter housing).. make sure the end is at a 45 degree angle to prevent it from getting plugged

x2 on both of those answers; I've experienced both and they fit the bill!

Ear shave = the big air filter boxes were removed (shiny ones, we call them the ears) and replaced with pod filters.

If it started slowly and progressively got worse, I'd suspect a loose connection somewhere. Check your battery terminals ground wire and coil wire connections, even your spark plugs wires too.
Carb cloggs usually just happen they don't slowly build up...(but they still can, so do check the stuff the others outlined.)

That doesn't explain idle and throttle. If it were bad connection, seems the vibration of throttle would cause problems. Sticking with fuel flow for one hundred Alex.

Should still be checked just to eliminate the possibilities.

When I experienced poogs, my bike bogged down & died while cruising.

Does it do it at all speeds? Given the same sinario?
I'm leaning to dirty carb. Sticky floats.

That was my point, you can suck some gas past the POOGS clog with full throttle since that increases vacuum on the petcock. At idle you don't need as much gas so not as noticeable.
