Yamaha DTXpress/DTXplorer/DTXtreme

I thought it was too good to be true,I had my first complaint about 
my e-drums AAAAAAGGHHHHHHHHHH!!!!!!!!!!!!!!!!!!.
  What is the best way to stop the kick pedal vibrating?,it seems to 
me that is the only problem that I am causing,foam round the 
beater,foam roung the bass pad,or put a few layers of foam under the 
whole foot pedal.Any other suggestions.
