A buddy has the audiovox cruise control on his 09 ST1300. I guess it doesn't matter what bike it's on but he has a problem. It works great except for when he starts to go down hill. It back off about 5 MPH and the RPM'S drop a couple hundred. He has no trouble keeping a constant speed on a straight road or going up a hill, just going down hill. He said there are switches on it that you set, ( I don't know anything about these switches because I don't have a cruise on my bike) anyway, for those of you that don't have a problem with your bike maintaining a speed, how are your switches set? Or do you have another idea what might be causing this problem
