OP After reading through the 22 pages of this thread of what seems to be very solid advice. As you had stated yourself you have limited mechanical ability which is not a problem, and your willingness to learn about you new bike is commendable(get a clymers manual asap), as it not a machine that can be ridden and put away wet. You had stated that you just want to get out and rip on it. That is a common denominator of most member here, we just want to get out and rip. That said you have two ears and one mouth for a reason. No one here would steer you wrong in helping you out. All the advise given thus far is sound and was given Solely to benefit you. 1. Sending your motor out to a builder who builds these motors all time will ensure everything is done right, through experience with this motor. 2. Sending your motor out will give you a correct baseline on how your motor should be working, thus allowing see, hear when something is not right. Then you can fix it. 3. Unfortunately you have chosen the wrong bike if you want have a fast reliable bike considering it unknown history. Banshees will empty you wallet fast. From my limited experience with them, I followed all the advice from members here and chose a builder to do my porting work. My builder also gave me advice on other parts that should be looked at since I was going for more reliably over a rocket ship. Also note that I'm in Canada, so very limited engine builders here. These guys on here have given sound advice. They are trying to save you lots of money and headache. Best advice is to listen. Sent from my LG-H831 using Tapatalk
