how is it that HD can say if you have them do any engine work on your bike it will void there warranty. was thinking cams. their SE cams. got email from service manager saying will void my warranty. just bought from them in august. 3rd new bike from them specifically. wtf is that about. do they not trust there own parts? anyone have any solid proof that the company can void the warranty, or is it time to go into managers office and well u know.
