49CC 2-stroke Engine Motor Kit, Pull Start Mini Bike 49cc Engine Single Cylinder Engine Motor for Most Air Cooled 49cc Mini Pocket Bike Mini Dirt Bike ATV Scooter

Both my son and I definitely noticed the difference in power and speed. This engine kit arrived quickly, but shipping cost was very high $30. We had to fabricate an engine mounting plate, the fuel tank is really small and the chain was longer than what we needed, but worked great after resizing...!Thank You, Luis...

Pleased with tolerances and compression. Spark plug has to be soldered. Broke immediately. Pull seems okay. No mounting hardware or alignment. Throttle seems fir tiny handlebar diameter. Chain small but all there. Have to do some maker fab to make it work. Put thinking cap on which is half the fun and challenge. Essentials present. Happy. Big wan grin face. Black motor.

Very good running engine lots of power but it leaks gas like a stuck pig. I work on these things so I know the INS and outs of them and I can't seem to figure out a solution.

What I ordered and fast

It is good and people saying that it starts leaking alot from the over flow u need to tighten a screw for the throttle so the carbarator doesn't fill up with allot of gas but my only issue is that it doesn't come with the bolts to bolt down the engine to wtv u want to bolt it to

Engine seems strong and sounds good. Clutches on the other hand are complete trash lasted 5 mins with one of my kids on the machine it was installed on.

Perfect

Installed got it to run but then could get it to start again leaks Gas like crazy out of the overflow good engine but valve seat is trash gonna contact them to see if I can get a new carb
