Default Idles fine, sputters and bogs on acceleration

Put gas in the bike last night, rode about a mile home, everything fine. Going to work this morning, it starts up as it always does, but sputters and bogs down as I get on the street trying to accelerate and go through the gears. Had to limp home and get the other bike.
Thinking it could be a clogged fuel filter or something in the line? I did have to put the bike on reserve on my way home last night. Can't see that as being the problem.
Guess it's as good a time as any to put the cams in the bike.

Sure would like to know why it's doing this though. Have to check into it tonight after work.

Any suggestions?

Hole in a internal fuel line in the fuel tank. Plugged filter as you stated.. Poor connection at the bottom of the fuel tank.

Forgot to mention, it's carbureted.

I checked the filter, removed the carb and checked the bowl. Everything looked good. One vacuum plug was badly deteriorated.

Put it back together, started up just fine. Took it for a spin and it still bogged. Adjusted the idle mixture and then it was fine.

Go figure. Not really sure what the problem was.

I'd add. Dump the fuel out of the tank. Look for water in the fuel. Replace the plugs if the diaphragm is OK.. Check Battery terminals..

Well, I thought I fixed it.

Back to the same thing, and backfiring. Maybe it's the ignition.

You just might have hit it when you adjusted the Idle and everything was fine --- I'm not familiar with your carb but the carbs that I am even some Jap bikes have a O-ring and a washer under the Idle screw , Remove your Idle screw unravel a paper clip bend a end to 90 degrees cut off to 1/16 inch and reach down in the screw hole tho hopefully find a washer and O-ring it might a couple of try's . Auto's do not have this only motorcycles, atv, ect -- you might also try to find a parts brake down , If the o-ring is there you will only find it in a over haul kit --- I hope that's it -- a easy fix , many people replace the whole carb because of this 10 cent O-ring
