the gas nowadays goes bad and can tarnish (if you will) really fast you should proably remove carb.soak for 24hr.s in a high flash solvent and blow out all passages

SOURCE: my vstar 1100 dies when in idle. acceleration is

Is the idle speed set too low? If so, adjust it, using the idle speed adjusting screw, to the correct idle speed (900 RPM). If that's not the problem, then check for air leaks between the carburetors and the engine by spraying WD-40 around the intake manifolds with the engine running. If there is an intake leak, the engine RPM will change briefly when the WD-40 is sprayed near it.
Aside from that, there are two other things that can cause your engine to die when it should be idling: the idle speed mixture adjustment, or low cylinder compression. Of course, if it was idling fine before, and the idle mixture adjustment hasn't been changed, then do a compression check, first. To idle properly, each cylinder's compression needs to be at least 140 psi.

SOURCE: 1100 yamaha 2003 vstar classic gas tank remove

1) Make sure your fuel petcock is closed, then detach the gas line coming off it (left underside of tank)
2) Remove the back seat (single acorn nut on rear fender)
3) Remove the front seat (two allen bolts at the back of seat)
4) There are two metric 12mm bolts under the front seat that hold the tank down. Remove them. The tank should be sitting loose on bike, but connected by some wires
5) Disconnect the white wiring harness under the bike. Tank is now totally free to remove.
6) Pull tank up and back at the same time, it will slide off the two rubber mounts at the front.

SOURCE: Vstar 1100 idling rough and backfiring letting off the throttle

It sounds to me that your carbs might be a little gunked up - you mentioned the gas may have been old, so it's possible that the smaller (idle) jets are slightly plugged up. Fresh fuel might do the trick and/or you could try using a fuel system cleaner and water remover. This problem might 'solve itself' with a little time.

As far as the backfire - this might be either from the carb issue or it could be related to that rattle you mentioned - you could have a loose connection at or near the head - this can **** air and cause a backfire.

I hope this helped!

Throttle bogs down like its starving for gas or air. plugs been changed new rebuilt motor and trans, carb taken off and gaskets cleaned what could cause my motorcycle to keep doing this

there is a coating in fuel tank these bits loosen and go into carbs and block all jets, if you havent done this and this fixes problem you best put an inline fuel filter on bike to stop debris going into carb, these filters are good for a thousand miles i would recommend a car on like they used to have on old minis they are £1.98 on ebay

Bogs out under throttle

It's either getting too much fuel or not enough. Has the bike been sitting?
