Hi guys I have 2" bar risers on my 1998 summit 670x and I need to go higher. I am 5'10" and i am thinking of 7 or 8" what size riser would you recomend for this sled? will I have to change all the cables to longer or just the throttle. also If any one has longer cabels or a riser bar for sale pm me. thanks for the help.
