cptriker1,
Limited experience as I have had my 86 only a little over a year, so take it for what it is worth.
Bike has been gone over completely by a very knowledgeable mechanic who is familiar with the bike and systems.
Carbs were completely torn down, cleaned and rebuilt with quality parts.
Haven't made any long hauls, mostly 1-3 hour rides, some by myself and some two up.
Mostly on back roads just enjoying the ride.
Just carrying usual items such as tools, spare items etc.
Most of the time we never get out of third gear, and that is definitely something that I had to learn.
Lugging the V-4 isn't the thing to do. Not that it can't to a certain degree, just not the thing to do on this bike.
I have found that short runs with a good amount of stop and go, the mileage can be down into the high 20's.
Trips that I have made by myself with more highway miles at 60+ mph and the mileage definitely goes up around 40 mpg.
Even at 70+ mph, run into much of a headwind and/or a grade and you will be down shifting to keep the rpms up.
