How did you know? Any damage done?

 

No damage to mine, doubtful there would be any. To check look at the boots, and carbs. You will know they are off if you push back the carbs and can see an opening.

Loosen the clamps, reinstall the carbs buy pushing them forward. Then richen your idle and up your idle RPM.

 

Why richen it and up the idle?

 

they made a loud POP sound, when mine blow off, but that was right after i installed my pipe, after my rejet it never happened again. oh and NO damage was done
