Any ideas on how to increase fuel mileage

I do about half my riding on motorways and half on slower A roads. Normally I'm doing about 80-85 on the motorway which is just over 6,000 rpm for me.
And that...for my 19 litres & £20-odd quid gives me 185 miles which, some clever calcs says, is 45mpg UK (37mpg with US-sized gallons)
This week I thought I'd try sticking religiously to 5,000 rpm on the motorway which I found is 73mph. I got 216 miles so that is 51mpg UK (or 43 mpg US).
So, thanks to my Maths O-level I could save myself 15% on your fuel bill by going a bit slower. Must...avoid....temptation!

 

Guaranteed results : put in a 1 tooth larger front sprocket.

 

Just head to your local Honda shop and trade in your VFR on a brand new Ruckus. 100mpg and you can ride in dirt.

Yes I'm kidding, but I'd be lying if I said I didn't want one of those little scoots!

 

On highway, other than not being way up in VTEC territory, the thing that mostly affects my mileage is wind: with a strong headwind, I get about 45mpg; with a tail/quartering wind, I can get around 52.

And yeah, this part of the country the wind can be bloody awful at times.

Added:
Just fueled up after several days of around-town and some highway riding. This is with chilly/cold mornings/evenings, and letting the bike idle a minute or more(depending on temp) to warm up: 42mpg. If it was city only, past history says would've been about 37.

 

carry corner speed.

 

"Lose some weight, ya fat fuck".

That's what my wife says to me, and I bet she's right. I'll get better mileage.

 

Modern motors are always going to get slightly worse fuel mileage in colder weather due to running richer.
I have scan gauge in my car, before winter I could get to work at 24mpg and home 26mpg. Now it's around 21-22 and 23-24 home.

 

Yep. Heck, my old Ford Courier got worse mileage in winter, carburetor, manual choke and all.

 

all the above, plus make sure your chain is clean, lubed, and in good condition.

 

I found myself rather well, PC3 map carefully tuned between 3250-4750 rpms where is the most of common roads throttle. Leaned more over 4500 till 6500, where 2 more teeth on the sprocket do the appropriate job. Superlean @ 5500 sixth gear, where appreciable economy shows on highways. A thing: I have found that a "saw" like design of the a/f ratio through the revs helps alot the driveability while preserving some notable mileage. I mean, a "flat" ratio, ( say 13,7-13,7-13,7 and so on) is a little worse than increasing/decreasing ratios. In facts. I don't know the theory abou it, it worked very very well on my Triumph Daytona ( triple ) and seems good for my vtec, especially at throttle responsivity.....

 

This may or may not work, but makes sense on a theoretical basis. Using high octane fuel in bikes with closed loop injection systems may improve the overall mileage if the oxygen sensor is good enough to detect the slight improvement in combustion AND the mapping can automatically adjust to suit. Whether this makes economic sense is a different question altogether, as the reduction in fuel consumption may be offset by the overall cost increase of filling up with premium.

I guess this theory could be applied in an extreme sense by generating a custom economy fuel map using an ECU remap or Power Commander etc with A-F ratio monitoring on a dyno, but I presume that this isn't what the author of the original post (with a high school student budget) was referring to when looking for tips.
