What i meant by stock topend was that i didnt want to but together a srock motor with all stock parts. I wanted to add some performance parts while it was apart. And i was trying to find a nice place to get the stuff from that was well known for there work and parts. Being that ive never took a banshee motor apart i will probably be having a shop do the work i just want to know what package to get. Im not looking for a drag bike im looking for a good trail and dune bike with alot of power.
