Review: 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.
Review: 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

## Questions & Answers

**Q: Is a separate exhaust needed to run this engine? If so which one?**
A: My son had one on his dirt bike already an you don’t have to have exhaust for it to run

**Q: Is this a right side or left side drive? The photos show both.**
A: The mounting holes are on the bottom. I purchased this as a replacement for my sons dirt bike motor. His clutch was fried and it was more practical to replace the engine. I only see it mounting one way. Chain on left side.

**Q: Automatic transmission?**
A: Basically it uses gear ratios in the gear box like a transmission.
