    • 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.

    Bolted up without too much hassle. Once everything was hooked up it fired right up and was happy. You really can't beat the price for an entire replacement motor.

    I was alittle skeptical for the price being so cheap but this engine exceeded my expectations! I have had several four wheelers and if they a maintained correctly they last a long time. I put this engine in a frame I had and it ran perfect and had plenty of power for me weighing 170lbs, the shift pattern was my only "dislike" but it didn't affect the performance. If you want these engines to last you must drain the oil that's in them from shipping, its low quality oil, break it in with some name brand 10w40 motorcycle oil then change the oil after the first ride.

    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 Motopartsmax.com they had no ideal where to get the parts.
