It depends on which lines you're talking about. The high pressure rocker feed line is definitely a candidate for stainless braided. I did mine after the plastic one cracked at the upper banjo. The lower hoses (herringbone originally) should be routed carefully and protected from abrasion by the factory spiral steel casings. These get stainless braid only for looks, like I've done with the fuel lines:
Gorgeous bike! Well, I certainly appreciate all your comments, you saved me some money. I will get the high pressure line kit in stainless with the stainless hardware along with a stanless brake hose. May get the Gates look alike hoses for the other lines as well, but being as the ones that are on there are new, I may not bother........ yet. Not high up on my list of priorities.
