I can't get my wife to even go for a ride in it - no worries about her wanting to drive it. And mine is a relatively tame street roadster.

You could probably disconnect the rear carb from the linkage fairly easily and quickly when your wife or friends drive it. It shouldn't be a problem running off of the front carb primaries since it's in the approximate center of the engine. But with the secondaries all the way at the front of the intake, fuel mixture distribution when the throttle is matted will probably be pretty poor and may cause some lean cylinders.
