still the same old knock.. now with a new problem.. my front sprocket cover broke.. I was backing it out of a parking space so my girl could get on and i hear and feel a thud.. sounded like i hit a 20oz plastic soda bottle.. i look around and see nothing.. I tell her to wait and ride it around a bit to make sure its ok.. then she hops on and off we go.. i start noticeing my speedo pulsing up and down it wont stay put.. then it just drops to 0... by this time im at home.. I was thinking the speedo was on the front wheel and thats when i see the speed sensor chilling in the center of the front sprocket cover.. so i reach down and notice the hold case is cracked and I can pull it out and see the front sprocket.. buddy of mine says it happens alout a slave support is the only thing thats gonna stop it from doing again.. he said the dealer should replace the parts but will probly try to get you to buy the support... $40.00.... you guys got any info on this? its going to the dealer this week
