you dont need different pipes or different carbs. it will work hella good with what you have. eventually if you want more top end go with some more top end pipes and bigger carbs, but for now you will be fine with the stuff you have. trust me, my bros shit ran goood with stock carbs. now that he has 33s its got more on top. you wont be disappointed. if you are concerned about the crank go ahead and have it welded. my brother never had any problems with his tho, and its still not welded. you might wanna upgrade to v force reeds or at least some aftermarket reed petals. that will help with the added flow. eric is a good guy and he answers the phone when you call his shop. dont hesistate to give him a call, he will help you best he can.
