CJR Oil Cap Crankcase Breather V2 - CJR Performance

This option has been updated for a shorter overall profile and now available in anodized black and anodized silver.

While the stock breather can be great for easy going everyday riding, it isn't sufficient with higher RPM abuse or an increase in power. Pressure and excess heat inside the cases increases quickly with harder riding styles. As the piston travels up and down in the cylinder the excessive rise in pressure can cause resistance for the piston travel and in return, rob power. With this increase in pressure comes a drastic rise in heat as well. This is the LARGEST crankcase relief on the market with a 10mm relief diameter to help keep these engines running cooler.

Our new breather is now available in two options, a straight and as 90 degree fitting option depending on your clutch cover needs. 

Set Includes -
(1) CNC Base Adapter
(2) O-rings
