If you are getting stumbling, and humidity is high, condensation in the tank occurs, if the fuel is older than a couple of weeks, phase separates... if you don't want to put Seafoam in it, put some isopropanol (a couple of ounces will take care of that water).
Stumbling can be a symptom of a TPS going south... you'll not likely have a catastrophic failure, just deterioration over time, and all the wear on the ceramic resistor boards occurs where you have the throttle the most... in the 10-20% range.
One of the things the FJR needs is good hydraulic fluid, I'd think on an AE it would tend to be neglected as that's such an involved procedure to bleed it.
The symptoms you describe we've heard several times with AE's... need good electrical contact, shift linkages moving freely, etc. and a good battery with staying power... Yamaha typically says 12.8V. While running the charging system will take care of it, and should take care of fans running if you could keep the revs up.
You could wash the bike all you want, no water should have gotten into anything including the gas tank, assuming the connectors are sealing.
Problem is, no one has AE info all in one place, so we have to search old threads across multiple forums to find what others did to solve the issues.
Keep yer stick on the ice....
