Matched right up
My son had a small 50cc dirt bike given to him. The clutch became inoperable. After looking around found this motor was more practical to buy then replacing the clutch. Received the motor and it looked great in the packaging even came with new grips and throttle and cable. Everything matched right up to the bike. Out some gas in it and it started right up. Made some adjustments to card for air flow and it idles and runs amazing. Very happy with a 5 year old who's ecstatic.

Works decent
Carburetor leaks if gas is held on float or needle issue maby pull start feels cheesy but it works and I’ve turned it over about 30 times now to plenty of power for a kid

Junk
Third pull. Ran it once and pull start broke right off.

Works really well!
Guys I have abused this engine in my pocket rocket and I’m not a small guy. I’ve probably over done this engine soooo many times yet it’s still going. Amazing engine when you just put the right gas in it!

Frozen
Edit** I mounted this engine to a razor quad that was previously electric. In less than 10 hours of run-time the clutch was destroyed.

Decent replacement motor
Came extremely fast. Did have a crack in the pull starter case but not a big deal. Way better than a four stroke which is what came on the dirt bike.well worth the money

Trash 49cc motor
Probably one of the worst pit bike motors I’ve ever had pull start failed less 24 hours after installation . And now they won’t replace it … great job guys selling cheap case metal motors .
