It's the ideal starter big bore kit for someone looking to get significant gain top-speed without excess tuning time.
NOTE: Properly break in your big bore kit and add about an ounce of 2 stroke oil to your gas tanks. 50cc oil injectors are not meant to lubricate 72cc bores. For break-in, we recommend 200-300 miles before running your bike full throttle for any extensive length of time. This BBK will not fit the early model AF05E Engines (PRE-1994). Boring and machining may be required.
