Well I suppose you ran through that 1/4 tank. use Seafoam as a preventive for now in the gas tank.
Cylinder balancing or synchronization will assist in lower speeds and idles, but they should be done, whether by you or a shop. It is an easy job but you will need either vacuum gauges, 2 to 4 or other carb stix. When done properly the end result is a smooth running 4 cylinder.
Idle is recommended at 750 +- 100, I like 1000 +- 100, for the charging system to work at the lower speeds.
The 1200 is a lot more torque producing than the 1100 but gear shifting is similar: They both like higher revs and in fact if you shift at too low a RPM, both will complain as evidenced by a growl or a chain vibration in the front of the engine. To stop this the balance will help plus the shift pattern at 2500-3000 range. Both bikes should easily reach their red line in at least the 1st 3 gears.
The carbs will need attention, both in the low end and in the upper range, but get some experiences with the bike so you have an idea how it is running. Both 1100 and 1200 get great mileage but that varies as to how you drive and tires, brakes, and if you lug the motor and these 4 bangers do not like lugging.
You should get by with 87 gasoline, if you get ping check the heat range of your plugs before going to a high test fuel, you will have to experiment. The use of ethanol at 10% may not be a bother, drive it and see.
As for the rear end an 80/90 hypoid is OK but anything thicker is bad when the temperature is cold.
Set your spark plug gaps at the minimum specified to alleviate and type of higher speed miss.
Have fun with it and enjoy!
