High Compression Cylinder Head 80cc 60cc
This cylinder head increases horse power for your 66cc 2 stroke bicycle engine* and greatly improves cooling of the engine.
It is very easy to over heat these bicycle engines if you drive fast or live in hot climate.
Poor engine life will result of running a hot engine, as the oil film cannot hold up to overly high operating temperatures.
This cylinder head incorporates a squish band which has been proven to allow increased compression while reducing the risk of detonation.
Please be aware that in order gain the maximum benefit from this cylinder head, you will need to bring the outer edge of the piston to (or close to) the top of the cylinder.
*The GT-5 engine has a different crankshaft assembly and piston than most other engines, and has low compression.
Adjusting the compression by decking the cylinder jug is necessary for the GT-5 engine in order to gain proper compression ratio.
These billet parts are as smooth as glass and about 2 minutes from a mirror polished finish.
Its recommended using a cold plug like NGK B8HS spark plug.
