| − | The biggest gains in power output come from aftermarket cylinder heads (see photo). Stock heads can also be ported for more power. MTS and others do this type of work. Pre-1974 heads are small chamber 76cc and are good for around 12-13 to 1 compression when a flat top piston is fitted. Race gas, alcohol or propane fuel must be used. | + | The biggest gains in power output come from aftermarket cylinder heads (see photo). Stock heads can also be ported for more power.
