Are these engines any good?

[KieranM]

well,
I have seen alot of engines like these on ebay. They are used in minimotos. does anyone know if there any good for a mini bike or are they just cheap Chinese dirt (the last bit was for Freakboy)

they would be fine for kids. look at how the clutch is done.

 

[KieranM]

yea it dosent look like it can withstand much. I just saw the sellers shop name

 

[mike75925]

it can be built up i guess, but in it's current state, it is maybe producing 2hp.

it can be built up i guess, but in it's current state, it is maybe producing 2hp.

and virtually no torque.

depends what sized mini bike.. if its the same size as a pocket bike then it would do alright but anythingbigger and heavyer it will be crap..

I have had several of those, don't buy it. its a 47cc Pocket Bike Engine. The carburetion on them is horrible. You ride it for 10 minutes. Turn it off and it wont start for over an hour, the bearings go out fast! STAY AWAY! thats my 2 cents

Ive tried but carb jets always get cloged and rings wear fast
