is there a way to tell with certainty whether or not one or both of my motor mounts are either broken or totally worn out? I think (and hope) I am getting false knock due to this. perhaps my 3" DP is hitting the frame as a result of my motor torquing to that side when i step on it, i had some clearance trouble getting it on. anyway, i think i might have a problem with the motor mounts, it does lean back and to the right when i rev it, is there anyway i can tell for sure?
