I have 7,750 miles on my 03 Zx-12r and the speedo just started bouncing wildly the dropped to the bottom. I have found a few 2000-2006 Zx-12r speedo consoles on ebay and was hoping readers of this forum could help me with a couple questions. First, is the de-install and re-install as simple as it looks (simply un-plug old console one and plug in new one)? Second, will the new (used) console show the mileage from the bike it came off? Any other issues I need to be aware of before buying a replacement? Thanks.
