HOW DO YOU KNOW what size swing arm you need? Is there a set size4" 8" 12", or is this another special order item? I know you have to change your chain,and i imagine you have to get longer brake lines. but will your stock shock work on the extended arm. with more horse power and having to change the chain anyways should i change to different sprockets. i have about five weeks before my motor gets back but i want all these little items taken care of. sure could use your guys help. Eric is hooking me up with all the motor stuff. its hard to belive that noone is running erics 48 hv carb, well if someone is can they give me some feed back. big baja or eaglecollector or someone give me help

 

I wish I would have done the 48, but I probably wont upgrade for the difference in cost. I added 6" on mine and am running the stock rear shock, gearing, and brake line. All of which are doing fine.
