Just wanting a few suggestions on what swinger to go with? I am going to start building a stock frame stock cyl drag bike, going with 4 mil drag port 36 pwk on alky probably going to end up with struts all around, as far as the swingarm goes I have no clue what size to get. Sure tires size and type has something to do with it basically just igve me a shot in the dark +4? +6? Surely I wont need bigger than that.
