so i have a 03 636 i just finished building from basically parts and ive been working on doing a custom tank with 1" lip for it and in the meantime i wanted to work out the bugs/break in the bike so i borrowed the tank/pump/cap right off my other 03-04 and the bike runs fucking flawlessy crispy mint and sounds perfect..problem is tho i finished my custom tank and mounted it with the pump/cap that goes with it and its like it instantly gained a bog off the bottom? so ? is does a 03-04 636 have a fuel filter INSIDE the fuel pump and over time i wonder if they can get plugged up with shit and still work but impede the fuel flow/pressure enuf to cause a runability issue?? OMR? anybody have any insight before i get a new fuel pump???
