IT sounds like it is the pickups not working (.telling it to spark) if not then it will be CDI UNIT OR ENGINE GENERATOR COILS

my yumbo had this problem as well. with the cover off on the side with the battery you will see what looks like a small amplifier with a white plug going into the top of it. i simply took mine off (1 bolt at the base of it) and cleaned it up especially the ground wire under the bolt you loosen. also try and clean up the plug and connections. before you start riding again give the battery a trickle charge with a 2amp 12v battery charger. if this doesn't do it try tracing the ground wire from the battery to the frame and make sure it is good and clean; you can also find another good spot on the frame to ground it. give it a shot and i hope it works out, j

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.

SOURCE: where is the oil filter on my yamaha V-star 1100

On the right side of the bike (right side when ou are sitting on it) just above the rear brake lever behind a small circular plate. remove the plate and the oil filter is inside (you will easily see it). Warning---on these bikes you have to drop the front exhaust header and right floor board in order to change the oil filter unless you install a after market oil filter relocation kit. If you plan on changing your own oil it is highly recommended to install this relocation kit.
