    • 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.

    Engine runs well. Started right away. Good price. You need to spend some time understanding the wiring before you get it up and running.

    Bought this as a replacement for the stock engine in my 150cc Puma Valentine scooter that I've absolutely thrashed over the last four years. It arrived quickly and was plug-n-play ready, though I did keep my old engine cover (because chrome!) and took off the kickstart. All I've done beyond that was initial fluids, 300 mile service and ride! While I'm being much kinder to it than my last engine, it's handling my 40 mile work commute and weekend riding just fine. I can't recommend it highly enough to get a scoot back on the road economically and quickly. Thank you!
