I have a 97 Banshee that has stock crank bored .50 cool head 185 psi comp stock carbs FMF pipes boost bottle reed spacers... thats all I can think of right now. It runs great I have no complaints. But you know how it is.... its never enough... Im just like most of the people on here... I wont stop untill I have a super cub putting out 120hp.. lol ...Looking to spend about 500 to 700 on it. What would give me the best bang for the buck... Im good with the wrenches so I will be doing the work myself. Would porting/polishtingbe worth the money or is there something else???? Thanks for the help!!!
