49cc 2 Stroke Gas Scooter Engine with Racing Air Filter for ScooterX EVO Pep Boys Zoom Bicycle Motorized DIY

I've had one just like this before model and all. . was pretty good for my application.

Love it

This engine works fine.I left the biggest sprocket on it .It did 18-20mph .Not real fast but fast enough for the bike.

Bought this got it put on today and not even an hour of run time and one of the mounting point broke completely as seen in the picture

Works great started on the second pull after priming you just have to make sure not to flood the motor or it’s very difficult to start again otherwise the motor works great and I like that it came with a oil and gas mixture container making it easier to get the motor up and running

After going thru some time removing old motor and trans on scooter and placing complete new motor and trans find out that Tran did not have any gasket so when you are to put any tension on the bolts from trans to engine it binds in side of trans cover and ABSOLUTELY will not move because it is binding ing up.VERY SIMPLE SOLUTION TO FIXJUST NEEDS COMPRESSION GASKET FOR TRANS TO ENGINE.THEN NO BINDINGBut they would not respondWould not send gasketCould not return. F’n stupidFeel bad for seller.BUT A LITTLE Q/C goes a hella long way.In short waste of time and moneta

put this on a sit-down scooter I have. bolted right up and wow this little thing rips now! its almost to loud for the neighbors. no issues.

Both motor mounts completely snapped off after only 2 months of light use. Buy at your own risk. I would NOT recommend this product. After they snapped off it blew oil all over the place.
