mosquito 24CC DX
expansion pipe port matched
HI/PO speed sprocket
Amsoil maximum performance 2 stage air filter.
I also drilled holes in the engine cover to help it breathe.
The int & exh gaskets were blocking airflow through the head finns so I trimmed them.

I attached a pic of my modified air cleaner and swiss cheesed engine cover on my DX.
