This professionally ported top-end replacement for your GT5 2-cycle bicycle engine will add instant horsepower to your ride.? These cylinders have huge transfer ports – these feed the fuel into the combustion chamber so bigger = better!? Also, the deck height is lowered for more compression, and the transfer ports are reshaped and directed towards the intake for more efficiency.
You also get a bunch of other goodies with this package.? 5 extra head and base gaskets in total allow you to set your port timing how you prefer.? It also allows you to run any type of head – from stock to our BMW 6.0cc high comp head.
