Might he be talking about valve train rattle(noise) in the genIII?
GenIV has a complete new valve train.
So, no noise/rattle? I never heard it on any of the Vipers we have had.
THANK you kindly for your responses...hope it answered SBMIANO's question too.

or your right foot will take care of it too....
