I know this thread is old but for future reference the 1p63qmj is a completely different variation of the gy6 and has basically nothing in common with a normal gy6.

First theres now 4 types of gy6s for buggys...Standard A-block....B-block...K-block....sym 150...and this 1p63qml. All have different stud spacing and share few parts between each other.

The 1p63qml is 62.5mm bore which makes it 177cc.
It has a completely different head bolt spacing.
It has a taller head with a 47/94 link/pin timing chain.
It has a counterbalance shaft.
It has an oil cooler.
Standard gy6 cams fit but i havent tried to run it with a standard or performance cam yet.
Parts are extremely hard to find.
