Twice now in 3 months, I have closed the throttle only to have the bike keep going about 60 MPH on the freeway. Pull in the clutch and the engine shakes and revs to 5K until I blip the throttle again. Obviously one of the TBs is not closing all the way, but I can not get it to do it when I am looking at it.
Has anyone else had this problem with a Hex Head?
Can the stepper motor cause this, or only the TB valve?
