  • 47cc problems plez helps

    hey i just bought a new 47cc pocket bike and i have been experiencing some problems there is a layer of oil in the exhaust pipe and around the area where the exhaust is bolted on. Some times when i am riding and i try to open the throttle up it stalls for a second then starts slow again and i also was wondering what performance parts are recommended any comments welcome
    Thanx alot

    what is your gas and oil mixed at

      reeds are very inexpensive and make a tremendous improvement in low end responsiveness..

      the engine seems to start easier as well. However, if you add reeds with a stock airfilter, you will need to remove the foam and internal plastic cage part of the airbox. (reeds tend to richen the mixture and you need to lean it out a tad by removing that part)

        please dont remove the sponge from your filter, this could and probably will lead to the main bearings and the big end bearing being damaged, change the filter to a high flow filter but dont run without unless your willing to rebuild your engine often,

          ok thanks for the feedback
          i am running 25:1 because that is what the instructions say but i have been going to around 32:1
          i wanted to but a new reed valve but idk if my air filter will work i am using a ada billet air filter for the stock carb

              its really easy.

              i run 40:1 (91+ octane), 25:1 is good for break-in, 40:1 is good to ride, 50:1 is good for race

              hope that helps

                  You carb may be running too rich also!
                  Do you have a Performance carb installed or simply the original one?
