I have a 2000 banshee with t5's, pro-design cool-head, delta force 2's, and k&n clamp on's. I dont have a bunch of money to spend but I want the most power I can get for a good price. I dont want nitrous. I have heard that putting my bike on methanol is a good cheap way. What do u guys recommend? And if I get a good bit more power outta my engine will I need to weld my crank?
