As I implied, and it has been my experience in the past that many dealers and sales staff don't have a clue about some parts that come on any bike. After I bought my CTX1300 it was such a rare bike that even though the local dealer had a few of them on the floor the sales staff had no clue what to say about it or how to sell it to any customer. Every time I was in there for some service I would wonder around the sales floor and proceed to educate the sales person about it and sell it to the customer for them... essentially. But that's just me. I generally learn more about things I intend to buy before I buy them that I can tell any sales person something they didn't know about that item. I did that all the time at Best Buy stores on their computers (of course my career was in computers, big ones and small ones, that run state government).
Oh, and on that note...
Maybe you can test something for me?
I was watching a video on the AK 550 from Inday Rider and as she was demonstrating it was mentioned and shown that when she held the button on the remote fob for a few seconds it turned on the bike same as the button on the central control knob. And then when she turned the central control knob to the ON position that the dash on the AK lit up. This may be wrong and I may have missed something on that. I watched that part of the video several times and I know I didn't see her push the button on the bottom of that central control knob at all. She only touched it once some time after that to open the seat but not to turn that knob on.
Previously I had thought I read somewhere that the button on the remote fob was a battery check. Then I read somewhere that it was a on/off button for the fob... which turns out to be false. But I did watch carefully in that video and the gal pressed the fob button for a few seconds and then turned the central control knob to ON and the bike turned on without ever touching the bottom button on the central control. I would like you to test that theory if you would please. I have no idea why that would be helpful to anyone but I might be missing something. It does seem odd that there would be a button on the fob that does nothing but shine a little LED light.
