im currently building my drag banshee, my 1st one and they truely are easy to break down and put back together, if you can read a book on it and turn a wrench and use a torque wench you can build it yourself, as mentioned already buy parts that work well together, porting is going to get you your power (along with the other goodies you buy) and your all set. there are good motor builders on this site and they will ntake the time to listen to what you want and guide you through the parts buying, the last thing you want is to buy a bunch of parts that simply wont work well together. check out this sites sponsers and call, hope this helps and good luck
