how to tell if a motor is seized? with pictures

[justinkr58]

i have just picked up a scooter for$ 80 they said it was seized..

so how do I tell if the motor is truly seized?

also does anyone know how to tell the cc of the motor, it has no cc markings on the block.

it is called Dadogs, i think it is titled as a 125cc but i cant find any markings.

and the only replacement scooter motors on ebay are 150cc or 110cc.


so i took everything off the motor (spark plug, exhaust,carb) then put a wrench on the output shaft and manually turned the motor and it is very difficult to turn,( i would say 50-100 ft lbs on my torque wrench.

so questions

is there a rebuild kit for this motor? is that what it would need? a new piston/parts

or
if i bought a 150cc scooter off ebay would it bolt right up to the cvt transmission on this scooter?

if i got a 110cc off ebay would it bolt right up to the existing transmission?

HERE ARE PICS OF THE MOTOR
