Clutch Service Starting

If you would like us to service your clutch for you, we can absolutely do that! If included with your engine, we will remove it and inspect the installation and the components.

All parts required will be billed out at retail cost. We will inspect and measure the components for excessive wear or damage, and will set the clutch to your desired specifications. We can also suggest settings based on your data (if available!)
