i am not sure if everyone know this but on Saturday when i took my bike in for the 500 mile check up the service person told me they was also changing the riser due to a the tack hitting them and leaving a mark on them in shipping you might want to check with your dealer and see if there is a recall on them so you can get them fix i think that is what the service manger told me was that either on some there was or on all but not 100 % sure all i know is they change mine out for me than
