The system is totally gravity feed , so if you have too much line to where the filter is lower than the bowl , that might cause some restrictions , also that particular filter I would guess would be for a system with a fuel pump , so it would have pressure pushing the fuel thru (not sure how free flowing that filter is) , I personally would just get (if you are insistent on using a inline) one of the clear inline ones at the bike shop as they are not restrictive and are meant for gravity feed systems like on these bikes ..... I am guessing you took the carb off and apart to clean it , did you happen to spray carb cleaner in/around the slide ?? , if you did , there is a good chance you ruined the Floating Valve Seal , located on the slide

Carb cleaner usually damages any rubber parts it hits , especially if they get drowned in it , they swell and get mushy and then just deteriorate really fast
Fuel Screw should be around 2-1/4 turns out from lightly seated (counterclockwise out) , have you (shut off the fuel first) taken off the drain plug on the bottom of the carb to see if dirt is actually getting in the bowl still or was ?? , usually dirt enters (more than likely) from getting thru the Air Filter , and ends up clogging jets or settling in the bottom of the drain nut , as the screen type tube in the tank where the fuel line goes , is usually sufficient to trap all but the finest of dirt (I found my dirt was getting thru the air filter , not from the tank , as I flushed and filtered the gas going into the tank using a Coffee filter and that will trap the finest dirt you can get , after the initial cleaning of the tank and gas cans (which did have sand in them both from filling at the track on windy days) , I have not had that issue of dirt in the tank , and still was getting a ton of dirt in the carb ...... The issue with that is , if it gets in your carb , then it can get thru to your Intake Valves , and then you have a whole new issue .....
So to answer your question , since that filter is not specifically designed for use in a dirt bike , I personally would not chance it and suspect it could be contributing to your issue , as mentioned , if you feel the need for a inline filter , then use one for a bike like this
