Key Product Features 

     2 Stroke Gas Bicycle Motor Engine PK80 66cc/80cc; Bore and Stroke 47mmx40mm; better adjusting Clutch a little before riding

• High hole Piston and Long connecting rod;Wide front mount; 8mm bolts to front and rear bolts;Allen bolts on motor;
• Slant head; 40mm alum intake stud spacing; manual EXCLUDED
• Clear up the cylinder transfer ports before assembling maybe some rough slag inside which maybe break off and cause the jamming of pistons and cylinders;fully attention on screwing cylinder to the end bottom,DO NOT screw M8 bolts tightly that maybe cause drill through the end bottom so add some gasket or washer on head is better way to prevent it happen; Attention on piston ring if put the piston out of cylinder, the piston rings are weak, better with right way install piston kit to cylinder
