is anyone running a plus 4 or plus 6 swing arm? cant decide on what to go with, also whats the advantages and disadvantages of the no link sett up? my engines around 75hp if that helps..Is plus 4 good enough, not tryn to just drag just want it controllable

i do alittle of every kind of riding really, how does the plus 4 do for launching on hard packed like clay? as of now with stock arm on it im in and out of throttle for 3 gears, makes it hard to win short drag races. but i think if u take all of the wheel lift out, it wouldn't be as fun
