## 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.
