I'm very strongly considering the CT 453 engine kit. And wanted to know if anybody here has it? If it is realiable? Does it perform well? Is a new clutch needed? What the power difference is? I'm looking for a low end out of that kit. And is a gearing change better for it?

 

the 440 kit is faster and puts out more power. They offer both 453 can not be raced in a 450 class but doesent sound like you are racing. maintance has alot ot do with motor life you will be creating an animal so you will probally double your stock hp if the kit is done corectlly. I recomend doing a clutch with it but its not my bike....
