      • For Automatic Transmission Engines, please don't start is at reverse. For Semi-auto and Manual Transmission Engines, please do start at Neutral.
      • Check lubricating oil level and fuel level regularly. Make sure they are sufficient and not leaked.
      • Please do not accelerate until it has warmed up for 1-3 minutes if cooler start engine.
      • All new engines need a initial run-in time. Because the surface of the parts is not that smooth, they need a time to run-in to have the parts get smooth and work together better. The initial run-in should be at least 500KM. During the initial run-in, please avoid full-open throttle and don't start it over 80 percent of the top speed. Make sure to clear all fuel and change new when initial run-in over. Be strictly obey this will prolong the engine service life and has it working in good condition.

    I would like to thank every one for getting my order out so fast. Just received them and everything is perfect. I will be ordering more parts because I am trying to rebuild two Panterra Fusion moped/scooter for my grand children. Again thank you. You will be hearing from me again. I also called some other moped shop to let them know where they can get these type of moped/scooter parts, because when I asked them before I found powersportsmax.com they had no ideal where to get the parts.

    The engine that I received from you came fast, in good condition and we're exactly the right parts that I ordered. The right engine was easy to find on your website and easy to order.

    The engine was the perfect match for the old one (unlike some competitors) and went on very easily.

    The other pieces I got from you were a good match for what I needed and I'm using them as I go as necessary.

    Thanks for making my life a little easier and for the fast and efficient job you do. I'm looking forward to doing business with again soon. G.

    I'm a new rocketa 50 scooter owner and finding a company online to get a engine from is a big plus. Mine was easy to find (unlike some other online sites), they were inexpensive and they were delivered quickly and in good shape. I have already ordered some more parts and will continue to be a customer of Powersportsmax.com. I was nervous to order online, but it couldn't have been any easier. I was notified by email through each step of the process by confirming the order, accepting the payment, filling the order and when it was shipped. All of this set my mind at ease and I new when to expect it to be delivered.
    Thanks for all that you do and for being so efficient with my orders. You have a new and loyal customer for life.
