Works excellent!!!
If your thinking of buying a pit bike motor or any motor, I would suggest buying one from X-Pro, these motors preform well, I have two of those and both have had no issues at all. Please make sure when you buy any of these motors that you drain out the oil and put fresh oil into it, I don’t trust the oil that they put into it. ... show more

the engine got shipped, but when i opened the box there was oil everywhere, upon looking at the engine, there was a big hole in the crank case. and the hose was split, the oil cap was broke. i didn't even bother looking for more, just packaged it back up and returned it.

Good engine
Cons: It's leaking oil after 10 miles. But it's running good. Bought this engine to replace the Venom X20 engine that I ruined. It's the exact engine except it's set up for an updated carburetor. Not the fuel system that comes on the Venom bikes. Started right up, runs good, and gets to a higher speed than the previous exact engine. ... show more
