Let me suggest never taking those knobs off. I've had my 07 apart many, many times and never removed either knob. The trick is to simply unscrew the knurled nut that holds the speedometer cable to the back of the adjust mechanism and then pull that panel off with knob and adjuster fully installed. Super easy (as long as you realize the speedometer cable is square and must be rotated slightly to go back into the hole upon reassembly).
That's because the two bikes are too similar... Add a Sportbike or a naked bike; something different, and you've got a better chance at justifying multiple rides. OR, you need whatever they are to be almost the same color. My brother had two bikes for the better part of a year un-noticed, because they were both red.
Well your'e a better man than I am. Pulling for you. 3 degrees here this morning. That would stop me from riding for sure. I just parked the truck last night. I may take a look at it tonight when I get home. 4 wheel vehicles suck. Why can't Yamaha come out with a car. If it is anything like the FJR it would just keep running without any problems.
Move to NC, TN or farther south and you, too, can ride for 6,157 days straight.
You may want to Google the legality if having a video screen between a vehicle operator and the road. Illegal in every state I can think of. I know, here, you'd get a quality ticket. That's way more than just a GPS screen, and since it has the huge potential for "distracted driving" your chance of having issues is very high.
