Hmm...this lower voltage ouput at low idle speeds has also got me wondering if this is what is giving the guys with efi bikes the stalling issue when their bike's idle is set below 1150 rpms. Maybe they are not getting enough volts at lower idle speeds to keep everything associated with the electronic fuel injection system going properly and if the idle speed is raised they are? Just throwing out an idea. Would be interesting to see how someone's bike with efi and the regulator/rectifier mod or mossfet upgrade is running.
