First of all; i drive(used to drive) every day so winter and summer,snow,ice or whatever.
when my sh goes into these values i KNOW it is time to dismantle the brakes.
Just the tiniest amount of dragging will cause horrendous millieage and a bit lower topspeed.
So check your brakes and i mean really really really check them.
starting with the rear drum brake( i assume you have a drum), check that it is absolutely not dragging whatsoever(!), if it drags you either need to loosen the adjuster or if that doesnt solve it you need to take the brake apart.
Take the whole bunch apart and carefully inspect EVERYTHING, the rear (drum) segments and movement and lubricate where needed, especially the key-and-axle that moves the segments as this will start to rot and rust with even one drop of water.
for the disc you should disassemble the caliper and closely look at how smooth the hydraulic pistons go out and back in, there should be little resistance, if you need pliers to push the pistons back in it means there is corrosion between caliper and piston or corrosion BEHIND the rubber seal(in the seal cavity) which constricts the piston and so the brake pad will be dragging.
The cause of this corrosion behind the seal is usually old brake fluid which has accumulated moisture in it, the aluminium behind the seal starts getting white cristal like corrosion and this corrosion pushes against the seal causing the piston not to move freely, miles dont mean nothing-time also deteriorates brake fluid just by standing in the warm and dry garage.
Because the sh engine is tiny it also means that it is very susceptible to drag in whatever form it may come, just loosing a few percent already has a major influence on topspeed and mileage.
You only have 16 HP, loosing just 0,5 hp to dragging brakes makes a big difference.
if you dont know what i am talking about: get help, dont screw around with your brakes if you dont know what youre doing.
and then finally to make matters worse; there could be of course also some other problem with the engine
i get 57 mpg with the set like in my avatar+ my 60 kg son+me@120 kg+90 kg trailer+15 kg topcase+2x10 kg sidecases ( so a total of 600 lbs) doing 8 hours to paris over hills and mountains going wot @ 73 mph....
