I have to agree it is BS, seems like harley will do anything to void your warranty now a days, the EPA put a scare into harley and so harley in turn will void warranty for what ever reason to prevent paying out repairs and since they are hurting in the business and not really selling bikes, that is what I think.
On my bike I was in the service department and talking to them and I told them I changed my oil and filter, my trannie and primary, this was about the 1,000 mile service, they said it will void my warranty doing it myself, like I said harley will do and say anything about voiding your warranty, we know it is BS
All for now Trampas
