Answer
Hi Tom,

The hoses are breather vent hoses. Check fluid levels of front and rear differential hubs. Ensure water in not mixed with oil and oils are at proper levels.

The hose should not be leaking onto the manifold. Check hose integrity and replace if necessary. Check hose routing and adjust if necessary to prevent damages to hoses.


See microfiche parts on-line at: "www.bikebandit.com" and "www.yamaha-motor.com"

Visit. "www.atvfrontier.com" and check out the Message Board. Lots of great intel about ATV's here. A good resource that I count on.

I recommend the purchase of the Service/Repair Manual for yout ATV. The manual will pay for itself with the first home repair. Also, check your local library for manuals. My public library has manuals and they don't mind if the pages come back greasy. It's great!
