Once again I feel the need to caution you, do not let this become a transaction between you and Severe Cycles. Your warranty issue is between you and Harley-Davidson Motor Company, and you don't want them saying you have to deal with Severe Cycle if their repair starts to peel six months from now. Deliver the bike to the dealer, not to Severe Cycles, and insist they handle the entire transaction. And you definitely need to insist on a repair order copy from the dealer to document the transaction.
For the life of me I cannot understand why Harley would pay more to an outside shop to do a repaint on a CVO versus just having their painted parts vendor ship a new tank and take the old one back, just like they have been doing with CVO parts for as long as I can remember. It makes absolutely no sense, but if you get the result you want then that's all that counts. Good luck.
