Ive never changed a front sprocket before. I got a 16t from eagle mike and one side has the word sunstar and the other has that huge looking washer about 2 or 3 millimeters thick. does the washer go towards the bike with letters facing out? I have a 2016. If that matters. I ask cause I seen a youtube video were the guy put the letters in. My other question is will they be a little louder than the stock? any help would be really appreciated!
