Has anyone ever purchased a part from a vendor that has a 1 yr guaranted warranty, then when the part breaks, have them not stand behind the warranty? I had this happen to a me. I purchased a sprocket from sidewinder, was told by the salesman that the part carries a 1 yr warrantee. told that if anything went wrong with the part, they will replace it free of charge. I purchased the sproket only to have it break in less then 2 months. Only had maybe 8 races if that on it. When i phoned the company, I was told the only thing they could do would be to sell me a new one. Please advise if this has happened to you and how did you handle it.
