Review KURYAKYN Breather Bolts 3/4 Inch Motorcycle Bike fits STREET

Introducing the Kuryakyn 9976 Breather Bolts, a high-performance upgrade for your 3/4-inch street bike's engine breather system. These bolts are designed to replace the original factory breather bolt on select Harley-Davidson models, providing enhanced functionality and an attractive custom look.

The Kuryakyn 9976 Breather Bolts are precision-machined from high-quality stainless steel, ensuring durability and resistance to corrosion. Their polished finish adds a touch of elegance to your motorcycle's engine compartment, making it stand out from the crowd.

These bolts feature a unique design, with an integrated breather cap that functions as a one-way valve. This valve allows excess crankcase pressure to be released, preventing oil vapors from entering the intake system and improving overall engine performance. The breather cap is securely fastened to the bolt using a locking nut, ensuring a leak-free seal.

Installing these bolts is a straightforward process, requiring no modification to your motorcycle's engine. Each kit includes four bolts, making it suitable for use on both the left and right sides of your engine. The thread pitch on these bolts is 14mm x 1.5, ensuring a perfect fit on compatible Harley-Davidson models.

In summary, the Kuryakyn 9976 Breather Bolts are a stylish and functional upgrade for your 3/4-inch street bike. They offer improved engine performance by allowing excess crankcase pressure to be released, while their polished stainless steel finish adds a touch of custom elegance to your motorcycle's engine compartment.
