Most people think the inline filters on plastic tank bikes are unnessacery (sorry for the spelling of that word, always gives me trouble) and many don't run them. I just put any pancake or cone filter on my bikes. I haven't had a problem with low fuel flow on any of them. My 250 doesn't have the intake filters either so that's my only filter lol

But yea just head down to your local autozone or napa and scoop up a pancake or cone (pancake filters flow more IMO and take longer to clog) lawn mower/small engine fuel filter that fits the fuel line
