Not worth the money
Got it fast. Started right up. Ran great, until it lost compression after about 8 hours. Never pushed more than my 45 pound son on his little dirt bike. Guess it was to good to be true.
R**!
Worth the money !
This motor is badass. Right out of the box it fired up second pull and runs like a raped ape. I'm 150 pounds and it gets me going 40 mph. Highly recommend.

Great engine for a pocket dirt bike!
Works great on my mini dirt bike for the kids. Installed in about 20 minutes. Put gas in the tank and it fired right up on a cold day without choking it. We’ve put about 6 hours on it now and it still runs really strong. It was installed on a coolster 49cc bike. My wife and I have ridden it a bunch ourselves and after about 4 hours we burnt the clutch up. I bought a 75mm heavy duty two paddle clutch for $11 and installed that in about 20 minutes also, including setting the tension on the chair afterwards. The new clutch (red spring) grabs very early in the rpms which my kids like. Overall it’s worth the fun, considering what it costs to go to a go kart track nowadays.

Not bad
Ngl this engine did exceed my expectancies. I weigh 180lbs and this engine can push me 28mph downhill and 25 on flat ground with full throttle. And my friends who are lighter can go even faster. Only issues I have with it is the clutch did wear fast and the gear box is starting to make clicking sounds but that can be because me and my friends aren’t gentle with the throttle. 2 things to note. One the pull start sucks, it broke the first ride this bike had but luckily I had a replacement and 2 the air filter came a little smooshed from shipping.

Bad clutch
Motor works great very happy with that but the clutch failed after 10 minutes and now requires a new one. Don't know if I'd buy again.

PERFECT for Coolster 49cc dirtbike
Good price, exactly what I ordered. Looks great, performs great! Did take some time to receive it, but it is worth the wait and every penny! If I ever need another replacement, I will buy again!
