Engine ID
 

This looks a lot like a GY6 Engine but the Engine codes that I find don't match up.

Any help? GY6 or something else?

DZ1P57QYJ ?

You have a 1P57QMJ

Here are the basics and the only things that really matters

There are 157QMJ and 1P57QMJ

The difference is how they are made and they have a few small differences
some 157QMJ parts dont fit the 1P57 qmj


All that really matters is is it a 157 or a 1P57

The QMJ YMJ or other combinations that pop up are irrelevant as far as i have been able to tell

There have been a few discussions on here that brake them down but they only really apply to place of manufacture as far as i have seen.

anything that will fit a 1P57QMJ should fit your motor.
If im wrong im sure someone will chime in but as far as i know the 3 ending letters dont really mean much.

You cannot trust chinese number system. Post some good pics of engine also what buggy is it out of
