Bike is done for the season...

I've been having a gas leak problem on the bike so I finally decided to put the bike away for winter already and start pulling it apart.  Got the carb bank off and found that ALL 4 carbs had cracked float bowls to to over tightening of the drain bolt.  The #3 bolt was in so tight I can't get it out and the #4 bowl had silicone in it to try and seal the cracks.  WTF?!  Of course the bowls are like the only part on the bike that you can no longer buy so it looks like this winter I'll be trying to find either new bowls or new carbs.
