The differece between KDU C000 & bn157qnj

Kwagga82 · 06-18-2018, 07:06 AM

Hello I havnt been on the forum for quite some time.

So i have two scooters one is a Kymco Movie 125 (engine code is KDU C000 {SN25})
and a Big Boy sportflite 150 (bn167qmj)

does anybody know if their are any major differences betwen the 2. The idea is to take the 150 piston and barrel and change it out with the 125. the reason is the bigboy is a wreck and the kymco is still licensed and running.

Any Ideas.

Thanks in advance
Regards

If Big Boy sportflite 150 CVT cover looks like this . . engine MAY be a GY6-B variation.
