i have the big 3 and a set of hetrick cams installed on my kfx450 im running 18 inch tires and would like to know what gearing is best for me. i free ride at the jersey shore which is all sand and whoops with lots of lil jumps and stuff. and do the cheaper steering stabilizers help with the twitchiness or should i just go with the $500 one. thanks for the input.
