Trying to install a speedo tuner on a '06 1000rr. I plug it inline (under gas tank, on top of case), put everything back together and when I start rolling / riding, the speedometer reads 0 mph, even though the red light on the tuner is on, meaning it has power. I thought it was a faulty product the first time around and returned it for a new one, but the same problem is back. I have removed and replaced it 3 times and if I put it back to stock, the speedometer works (although still off by a few mph). Anyone have this problem? The instructions are generic to any bike. Wondering if I have the unhook battery, or if I'm missing something. Thanks in advance.
