Hi Tim,
Have had my GenMars on for about a week now, like others first time took a while, next time would be five to ten minutes max. Check to see if the throttle cables get chafed by the bottom of the ignition assembly when turned to the right, mine did so added spiral cable ties just like in the low beam/high beam mod. Would I buy them again? Maybe, didn't notice a great benefit, have them full back now will try them full forward later, no clearance issues either way.
