The brake may still be slightly sticking and motor is using more work. or floats may have gotten stuck

Chances are the main filter screen is plugged with rust and trash. The reserve filter screen doesn't get used much so trash hasn't been drawn into it too much. Remove the gas petcock assembly and clean it. You may want to consider a liquid tank liner. It will seal the rust so that it will no longer be a problem. Google “ kreem liquid fuel tank liner “ or go to www.http://www.4secondsflat.com/Fuel_Tank_Sealer.html

SOURCE: 86 Shadow VT500 suddenly losing power/bogging down

first thing to do is to check fuel level. you mentioned about 290 miles since you owned it but no fillups. did you get gas from same store? not unusual to pickup trash or water in fuel from conv. stores. with that out of the way, look at your plugs and see what they look like. black and sooty would be fuel fouled and very white or very light tan would be lean. if plugs and fuel are eliminated, it could be the result of a stator coil starting to go south. these will require special tools to diagnose.

Vt500 missing at 4000rpm


Backfiring on deceleration is typically caused by carburetors that are out of sync. Having the carbs synchronized should improve or eliminate this.
As for the driveability issue at around 4,000 RPM; has the bike sat for more than a few months at any point? If so, the carbs could be partially plugged with gasoline varnish. Before doing a cleaning of them, try draining the float bowls. Sometimes a little moisture will collect in them and cause both backfiring and poor performance. Also, your bike uses "CV" or "Constant Velocity" carbs. These use a vacuum actuated rubber diaphram atop each carburetor throttle slide. Remove the four screws that attach the chrome cover to each carb top and carefully inspect the round rubber diaphram inside. If you see any sign of cracking - or holes - in the rubber, then you've found the problem.
