Gangsta hold up and let me test this setup out...IMO 3 up in the rear would be to much, you wouldnt be able to keep the front wheel down...Ive got -1/+2 and w/ a strap I wheelie from shifting from 1-2 and 2-3...Im gonna rip the rear sprocket off Thursday and go for some runs down an undisclosed area...Oh yeah by the way it is loud as shit w/ gearing...
