Works great for an option to relocate your breather tube. Looks great on the bike no worries about any possible blow back iol getting into the air filter now.

Good product. The only thing I would like to see changed is the fitting for the breather hose should be barbed.

Quality product, great price

 Chowder Posted:

Great part, excellent fit and finish, works perfect. No more oil sprayed down the bottom of my bike. Was skepticle that it might add some back pressure, cause leaks slowing up the breathing but have had no problems at all. Well worth the very low price!

 txjammer Posted:

Works out great when used to route breather from carb. It stopped the oil spray on the side of my bike. Even after 1,000 miles, no oil anywhere.
