Where do I find fuel vent on 2002 Yamaha v star classic

SOURCE: 2002 Yamaha V-Star Classic 1100 Will not run over 70 MPH

Hi,
The first thing you need to check is the air filter. Sometimes critters can get into the airbox when a bike sits for awhile. Sounds crazy, but it has happened to me. If nothing is blocking the filter, give it a quick clean since you have it out.
Next things to check:
Faulty diaphragm
Improperly adjusted fuel level
Clogged or loose main jet
Faulty fuel pump
You may not be able to check these on your own, but these are the next likely culprits.
Hope this helped

SOURCE: how to lower the idle on a 2002 yamaha 650 v-star classic?

under the left side of the gas tank you will see i black knob/screw at the end of what looks like a hose. the knob faces the rear of bike. that adjusts the idle. its real easy to find and the only adjustment you can make to the carbs.

well it sounds like the float needle is not shutting fuel off whin the bowl is full of fuel you can lightly tap on the bowl of carb an that may make it stop what has happend is the bike has sat you may need to run a little fuel treatment through it or sea foam and that may clean the end of the needle off the way it works when the bowl of the carb fills with gas the float raises a needle valve into a brass seat and stops fuel flow into the carb fuel get old and starts to develop a tarnish on that nice pionty valve an then it won't stop gas the overflows just prevent to much into the motor try some fuel treatment and run it it may fix it self just from fresh gas an being driven worst case is having to clean your carbs still not to bad hope that get you fixed up
