quick update, my cr500 rear rim wheel and brake caliper/master cylinder came today.. swing arm should be in tomorrow. still waiting for anyone to shed some light on the wider wheel hoop issue, this one pictured is only 2.15", i wanna run a 120 at least so i know ill need to replace this for a safe fit, they sell aftermarket wheel hoops (2.5") for around 125 bucks, but what issues would i have if i bought say a 4" hoop? would the chain rub on the tire? im also starting to think about the sprockets and how they will line up, of course i wont know what im getting into until the swing arm comes and gets mocked up.. any thoughts would be great! thanks
