Motorcycle Repair: blew my carb out of intake boot, fuel stabilizer, bench test

Question
hey chris...thanks for your help with the battery question...the other thing is this:  i was about to put my bike away for the winter (canada) and i went to the gas station to fill up my tank and put some fuel stabilizer in it and when i went to restart the bike it wouldn't start.  That didn't  really suprise me as it doesn't like to start when it's warm.  But then after a few minutis to cool it I tryed again and was really cranking it and it let out the hugest backfire I ever heard.  All the people around ducked cause it sounded like a gun went off.  I then waited another 15 min. and tryed to start it again and the same huge backfire happened.  I walked it home and put it away.  Now it's time to get it out and get riding again after 6 months of snow and desperatly need some help to fix it.  Got any ideas?

Hi, newbie here...I think I blew my carb out of the intake boot.  How do I remove the pods and fix this problem?  Also, If my battery is dead can I boost it from my car battery?
Any help is appreciated.  85 Yamaha Virago 500cc

Hi Lee.
 What is it that makes you think that the carb blew off of the intake manifold?  It takes a huge amount of force to do something like that.  If it did, then there is more damage than you can, likely, fix.

Give me all of the symptoms and every detail of the problem and then we can fix the real problem.

As far as jumping the bike from a car battery, yes, you can, but DO NOT DO IT WHEN THE CAR IS RUNNING.  A car battery produces more than enough amps to start your bike without risking the electronics on the bike by doing it with a car's alternator adding way too many amps to the mix.

Answer
Hi Lee.
 Start by checking the ignition fuse, then the valve and ignition timing.  Pull and clean the carbs, since you stored the bike with fuel in it.  check the ignition coils to make sure that they are within specs.  There is a bench test proceedure, as well as the specs, in the repair manual for the coils.

Also you should check for shorts in the ignition system from power to the coils.  Use a multimeter for that.

Good luck.
