With this service we bore out your crankshat and then Fill it. We use Oem Spec Silicone that provides great performance and longetivity.  The silicone creates a "ramp" to smooth and guide airflow to the ports creating more power and quicker revs. also reducing crankcase volume to better "charge" the combustion chamber. Also when we bore out hte metal to create a void for the silicone teh crankshaft is lightened making for quicker spool up from less rotating mass.


**Please send us ONLY the cranksaft for this service**
