I hemmed and hawed when bought my 04 Road King to purchase the extended warranty and I ended up purchasing it. Ofcourse my dealer gives me no written info on the coverage so I call the ESP center and ask some questions about modifications that void the warranty. I was told that I can do a "stage one" upgrade which means slip ons no head pipe change high flow aircleaner and a "street legal" stage one download for the efi. That kind of bums me out but I do want the warranty as I have allready used it for a inner primary seal leak ( I have replaced them my self and could do it but for a $50.00 deductable why ot just let them have at it). Does anyone have experience with the stage one download download? I would have prefered a daytona twin tec or power comanderIII but I think a three year unlimited millage warranty is worth having with a bike that I bought with 20,000 miles on it and have put 3000 on in 6 weeks. I will try to put this warranty to the test!!
