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.

1P63QML Rocker Arm assembly
I know this is an older thread - sorry to dig it up - I bought a second hand buggy for my kid and had to redo the top end - putting it together i realized the exhaust rocker arm was seized. For th elife of me i cannot source one. Any ideas on a reseller that i can get one from? I know its an oddball engine
