Here are two solutions for you:
A - Take the carberator off and soak it in some good quality carb cleaner for about 1/2 an hour. That should take care of any residue in the carbs.
B - Alternatively (and for the less technical minded) there is a great product called Sea Foam. Try to find it at your local CSK auto/NAPA/Wal-Mart. Pour a small amount (maybe 1/4 ounce) into each cylinder chamber (take out the spark plugs), try to pour a small amount into the carbs (a turkey baster works great for this), and pour the rest into the gas tank. Let it sit for 5-10 minutes, then start it up. *NOTE - the bike will start VERY hard at first until it burns through what's in the cylinders. ALSO the fumes will be EXTREMELY strong and suffocating - make sure you do this OUTDOORS preferably, or at least in a VERY well ventilated area.
Good luck - I know how frustrating these things can be! :)
P.S. - I am a proud owner of a V-Star 1300 - great bikes! :)
Hi I would change plug cap and check HT leads also check coil or coils and wire connections you some power at the coil or coils could be a bad connection but check the list ive had the same happen to me mine was a bad plug cap I think you will find it good look
If they did that, then they may have also wrecked the alternator and anything electronic (gauge head and ignition control module?) in the bike. It shouldn't have damaged the starter motor or the lights, though. Check & see if the lights work - try the brake light, that's easy. Headlight, too. The neutral indicator light should be OK.
If the lights work but none of the electronic stuff works, then try to avoid that friend when you have a bike problem. You'll need to trace power to everything electronic - anything with a circuit board inside - and verify whether that particular circuit board works at all, replacing it if it doesn't.
The alternator itself (the windings) should be fine, but the voltage regulator (probably inside the alternator but possibly a separate module) will likely be wrecked.
Nearly all electronic devices are sensitive to battery polarity, and can be destroyed if that polarity is reversed.
Find the starter solenoid and short across the two terminals, if the starter works you have a bad solenoid. If you hold the starter button and tap the starter with a plastic hammer and the starter works, you need new starter brushes. If anything else is wrong with the starter you need to buy a new starter no new parts are available.
clean carbs ,fuel filter, air filter ,plugs , try adjusting carbs for fuel intake i had to mark mine where they are supposed to be adjusted at .i have a tendency to ride hard sometimes.they get out once in a while.
if it's still fitted then connect across the main solenoid terminals with a spanner or screwdriver and it will turn over...if removed connect it to a battery with the body of the starter connected to the negative.
Very possible the one way starter clutch is about to go out on you, which is located behind the flywheel, Should be repaired by qualified service tech, as it requires removal of flywheel as it is attached to the backside of the flywheel, extensive repair, and expensive as well so be prepared.
Did the rebuilt start come with different size shims?
Did you experiment with different combination of these 3 shims?

Yamaha use power clips to hold down the stater gear and the reduction gear.
Did you replace these clips?
Weak springs is very common on Bendix system.
