ok here is the deal my stock cylinders are .80 over stock port. so i'll need to resleeve or try to find some fresh ones on ebay. i'm looking to port my next set. so the question is to go through the time and money to find new jugs wait to have them ported. or just go with a cub motor. it wont be an all out drag bike but i also dont ride any tight technical trails. so sorry for the long post but what do ya think
