I found that there are two bolts that hold the air box to the frame. Loosen those and push the air box forward as much as you can. That will move the carbs closer to the engine leaving less room for the bots to move. Also car clamps work well.

 

I'm glad you all put this information on here cause my right carb boot just blew off tonight. It seems like all the things that I've been reading about on the post are happening to me and i've only been riding it for 2 weeks. I hope my whole some isn't like this. Thanks for the info guys.
