You can quit wondering if it will ever come because the all new 840 Kit from Carl's Performance is here. This is one of those engines that puts a grin on your face when you pull the trigger. To simply put it, it's fast! The 840 kit comes with a set of new cast cylinders plus head set, new piston kits and all necessary gaskets. Also included are larger throttle bodies, bigger injectors and full upper case porting. Best of all, it runs on premium pump gas. Also required (not included) are V-Force III reeds and SLP single pipe.
