Review: 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.
Review: Very weak, no better than stock! - It says race engine but it's the exact same as the stock engine! People report 46 and 49mph, they must be pushing it up to 20 to get it going! The 14t gear on front will not even pull out with my 6 year old son on it! If you want a direct replacement you will be fine as long as you use your stock cog! If you want performance stay away! JUNK!

## Questions & Answers

**Q: can  the moter go on a uber scoot 2 speed 50cc**
A: I don't know what that is but is it semiautomatic or a 2 speed auto belt drive setup like gokarts with torque converters? If it has a gearbox with shifter than it would have to be separate from the engine itself most motorcycle gearboxes are built in to the engine thus they're one complete unit so you cannot mate the gearbox to another engine. If the gearbox is its own unit and separate from the engine meaning not built in to the engine than it is possible to use this engine yes. Now if the gearing in your gearbox is too tall the engine will struggle. You can help the engine struggle less by changing to smaller front sprocket or a larger rear sprocket. This should cover your question and any others you might have. If not I will provide any info I can to help further.

**Q: What is the black wire coming outa the engine near the spark plug with the connector on it for?**
A: It's for a ground or the kill switch. Can't remember.

**Q: Does this use a #40 chain?**
A: Can't  remember I gave up on the engine and put an electric motor on my bicycle .  I gave the engine to my older son and said try making a chain saw out of it . lol

**Q: Is the fuel tank included in the product when ordered ?**
A: No
