Can someone please HELP. My bike idles fine once in a while like every day I go to take off from a light or a stop and my bike jerks like it's running out of fuel but it has a full tank. Can some one please help me. I already took the fuel
line off the carb and there is fuel flowing fine to the carb.

​

Stumble at initial throttle is sign of a lean condition

Check for intake leaks

Thank you guys. I promise not to do any unneeded posts this time lol. Well I do have a in line fule filter it is at bottom of line by bowl than she goes up into feed carb. I did not pull anything out of caps should I? It is a pingle or something like that fuel filter.

Yes it did and that's when she fired right up. So it's cool to have no vent in the caps? My dog will not blow up cause she can't fart.

I would pull off the air cleaner and look down the throat of the carb..... give your throttle a twist and verify it's squirting fuel into the carb...

Guys sorry I'm being stupid , but should I take the vents out of my caps regardless? Is it safe to do? I am going to take the filter out of the external gas filter in the am. I am also going to change the pet cock should I get any brand or should I call BDP? Last thing should I counter clock wise the Acc pump screw on the carb?

If you we're having issues with the above items they would be persistent. Its safe to pull the plug in the gas cap. You have the best made petcock made, but you can pull and clean it.
I would ask you when does this issue happen? Soon after starting the motor and taking off? Are you using the enrichment lever when you start the bike? If so how long do you leave it on?

Check you Petcock Filter as Ray suggest, hopefully no liner on it. While you have you tank or tanks empty check in side through the gas cap with a flash light (please don't use a match! ;))and see what condition your Tank liner is in. The factory liners are notorious for failing. Symptoms: Bike starts fine because liner material has settled back on bottom you take it for a ride it starts moving again and blocks petcock or cross over tube, if you have split tanks. Bike will buck and sputter, running super lean due to poor fuel flow and or starvation and quit all together.

I would remove one thing at a time to cancel out possibility's
-remove filter in external gas filter
-remove vents from gas cap
-pull the pet cock out and clean
-maybe then Acc pump screw
