Well, ok, ive had my shee for 2 years now, When i bought it it had/has a Duncan National kit (for those of you that dont know Duncan National kit ). I gota say the motor kicks ass, Smooth strong powerband awesome for the flattrackin i do. I make my way out to pismo ocasionaly and i can honestly say i dont think ive ever been consistantly beaten by a shee, Even most the crazy long drag bikes i can run with (There have been acouple full blown Rigid nitrous drag bikes that it wasnt evenclose but im talking about rideable bikes) But here is my question, How come it seems like there isnt much about his kit around? Its been so good for me and there is another one that races with me with the eliminator kit and his results arnt quite as good but still an awesome engine. Thes motors on the track have no problem handing it out to the 450's. Here is another question, For me it was easy my kit has everything i want (for now) and came with my bike when i bought it. As a buyer how do you decide who to go with for building an engine, porting, carbs pipes ect. Not like you can realy test out porting, and once you get someting you cant go back. I dont care who you pick but how do you decide one builder from another??
