Thanks.. How would I tell if the motor is a 90cc.. It's automatic and has no kick startAccording to the Cyclepedia VIN Decoder, it is a 2008 Hensim 90cc, as seen below

The displacement is usually found on the cylinder in raised numbers and letters. Post up a pic of the engine VIN located under the front sprocket if you don't mind
Ok..Thanks And its automatic and it just has electric start..From the information in the pics above, it is a 50cc (48cm3) engine, the 39 in the engine VIN means 39mm bore size.
I don't see a shift shaft coming out of the engine case, I'm leaning towards a PO replacing the original engine with one from a kid's Chinese quad. That's probably the reason why you don't have a kick lever either.
