I let my Yamaha V Star 650 idle for about 10min with the choke on. I started to smell something funny and then my bike was smoking. I turned her off immediately and about 5 min later when I was ready to leave she started right up no problem. Is it possible I just let her idle with choke on for too long?

i would say its either drawing air or the carbs need setup. You have to check the breather pipes and the rubber manifolds for cracks or splits.
if carbs need setup, then its best taking it to a good garage, to have them balanced and adjusted.

You can go to your local dealer and they usally will copy it out of ther service manuel for you.When you say passing lights do you mean highway lights?

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.

Fuel filter is located near the fuel shutoff valve within three inches. It is inline between the shutoff valve and the fuel pump (towards tank).

The fuel circuit is: Tank/Fuel Pump/Fuel Filter/Fuel Shut-off Valve/Carbs.

You first step is to check for fuel delivery to the filter. Make sure the bike is cool and no iginition sources are nearby. Disconnect the inlet line at the filter and turn key on and crank engine (to trigger fuel pump.) Do not try and start at this time (choke off).

If fuel is adequate to the filter, check the filter by blowing through it, it should easily pass air. Replace filter if questionable.

Next reconnect the fuel lines and remove float bowl drain plugs in the back of the carbs (2 per carb). If with key on and cranking fuel pours out of these ports then you probably have clogged fuel jets. If not then the float bowl needles / pipes could be plugged with varnish from dried fuel. You can try spraying carb cleaner into the fuel inlet to clear the varnish and then retest. Careful not to spray carb cleaner on yourself (wrap straw with a rag).

If you have good fuel flow to the carbs and bowls you probably have varnish plugging the jets. You should remove the carbs and clean them thoroughly.

Hope this helps,

That is the problem,You need to clean the carb jets and get the gum out of the bowl.
