To be honest as I have built a well set up trail machine, don't try building it yourself, it will cost a lot of to setup a banshee to handle good one trails. Check out mine in the for sale section. I spent a lot and cant even get $4000 for it. Banshee cost a lot because a lot of the stock parts could not withstand the abuse with the rocky conditions in the Appalachian regions. Not to mention the stock a-arms, suspension, and shocks are horrible. I recommend buying one already setup, you will save a lot of money. I continuously had problems with the adjustment built working loose on the swingarm no matter how much a tighten them and is why I bought a laeger from a guy on here. I was also able to get nice one piece GPR steering stabilizer w/ handle bar clamps that really helps over rough rocky terrain. As other members stated, advancing timing, shaving heads will really help. Since banshees need air in the radiator, I also flushed coolant and use engine ice and put a billet impeller to help in tight wooded conditions for lower speeds. Geared down also for this.
