TWO STROKE MODIFICATIONS

 

2 STROKE HEAD AND CYLINDER MODIFICATIONS $349.95
Includes the disassembly and cleaning of your cylinder. Exhaust valves (where applicable) are cleaned and inspected for damage. All airflow port passages are carefully inspected and modified for superior airflow. All porting specs are designed from computer programming and exhausting research and development in the field. Cylinder heads are modified to compliment the change in cylinder airflow. All cylinders must have a head modification in order to maximize cylinder porting benefits. Cylinders are reassembled and exhaust valves are timed.
