i was putting on a protaper big bar kit for my little brothers 50 and the triple plate is not fitting on right. the little metal piece that holds the front brake line (in front of the number plate) is blocking it from going down all the way. We are most likely grinding it off if we cant find a solution. but i was wondering if you know if this is a common problem or if there's some thing wrong. help asap! Thanks alot.
