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. Best of all, a quick connect release dipstick for checking oil height in the fastest way possible!
