Universal Parts 61mm Cylinder Kit - 161QMK GY6
Description
The Universal Parts 61mm Cylinder Kit is a complete OEM-replacement cylinder assembly for GY6 161QMK 169cc engines — commonly marketed as "200cc" — found in Chinese-made buggies, ATVs, and scooters. This kit replaces the cylinder, piston, and all associated hardware in one package.
Important: These 161QMK engines use a wider 79mm diagonal stud spacing than standard GY6 125/150cc engines. Verify your stud spacing before ordering — this kit will not fit standard GY6 cases.
