Hello i`m a new member from the sunshine coast b.c. I have a 2007 max with a problem with the v boost, I have had the motor out of the bike for a partial rebuild (for ingesting a small piece of metal ,I will tell another time.) I have a flat spot @7000rpm. From 6000 to there its opening, then flat, then picks up from 8000 to 9000. carbs have been checked , the v boost cycles open, closed,and slack uptake on key turn . I have unplugged the round boost connection while the butterflies are open and away goes the flat spot, I have put in a used servo motor and no difference so can rule that out , next the control unit or the boost vac sensor are suspect ?? I have checked the vac hose, and done the cable adjustments , gotta get boosted arrrrgg! if anyone can help thanks lots!
