Replace water cooling with air cooling.
Get a straight thru design, better acoustics and airflow, more
horsepower.
Make the valves expand and contract at different RPMS for different
pitched sounds at different motor speeds.
port and polish interior for improved airflow and efficiency,
balance organs in order to attain higher PPM(penetration per
minute) with less friction, thus more performance.
Lighten body organs to minimise energy loss and for maximum
enjoyment, lighter components = less energy used and higher
efficiency, better handling also.
