2005 Yamaha yz250f carb cleaning, wasn’t a complete tear down just a simple cleaning made sure to take off all the jets make sure there was no dirt in them and sprayed carb cleaner through every hole in carburetor. Then did a quick adjustment on the mixture screw might do a more in-depth video on how to do that when I get a longer one from able which is available here\/
