The casting cylinder head increases the horse power and this greatly cools off the engine. Would result better performance and longer life for your 2 Stroke Bicycle Engine. Casting cylinder head Height Max:51mm-52mm.
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.
