Roketa Go-Kart buggy Model

[Justice442]

Hello all I am a newbie to Buggies,

A friend gave me an older Roketa Go-Kart buggy that has had the motor rebuilt. Trying to figure out what motor it is. I have looked all over and can't read the numbers on the motor. The only numbers I can find are GY6, Vento and the vin on the frame: L4BSCKLC656000784 I believe. Any help would be great. I was told it was a 150cc. I know whats wrong with it and so far ordered the wrong part, the Cylinder block and piston kit. It currently has the BBK 63mm. The hole pattern for the cylinder block is 57mm center to center bolts. Those are 10mm guide dowels in the pic

Thanks guys and gals

First start by measuring from top side of cylinger diagnally center to center. You will record either 3" or 3 1/8" diagnally center to center. It has to be a 150cc to have a 63mm cylinder. Its possible it could be the less common B series engine 3 1/8" pattern but I doubt it since I've never seen a 63mm kit for the series B engine. Also Vento is a scooter brand and their engines are not used in the Buggies. Where did you see vento ? What part did you order and why was it the wrong part. Since we are not physically there the more info you supply and pics the better were able to help.
