Hey guys. Building a custom blast for my son this winter I got a 2004 stock bike with out a motor and some odds n ends I'm thinking of doing a +4 swing arm with a 400ex shock and a banshee alxe wheel spacer two or no would that be 2 wide? I'm having ken do the motor for me I got a spare 240 vito with the +3 stroker hes going to do the porting an mill the head for me. Carb size and jetting would be helpful have a couple banshee carbs laying around would those be better then the stock one? And want a longer steering stem and suggestions? Going with the asr +3 a arms with the yfz shocks any other suggestions would be helpful thanks
