CJR Oil Cap Crankcase Breather - CJR Performance
CJR Oil Cap Crankcase Breather - CJR Performance - Straight is backordered and will ship as soon as it is back in stock.
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.
2 Piece Set Includes -
(1) CNC Base Adapter
(1) Straight Fitting or (1) 90* Fitting
A crankcase hose color option will be available soon, in the meantime use the link provided for 13x18 rubber vent hose - https://www.amazon.com/dp/B07TD53NFT?ref=ppx_yo2ov_dt_b_product_details&th=1
