With 17/34 sprockets, 60 mph should show about 4K on the tach. It could be a malfunctioning clock.

Buzzy's revival: '82 Heritage Special

But the clock is so pretty, how can this be?
Ok, I'll be serious, can I discern something by looking inside the gauge assembly?
I would not be able to. My beautiful and original tach is failing. It's whining and the needle is unstable. I'm taking it off before I ride again. I may send it to Joel Levine.
Thanks for that link. I copied it to my original post so I have it in one place with the other links.
This company seems pretty cool!
I haven't used him, but I've done enough research to be confident. The work is expensive, but the clocks come back as new.
If you are soft handed and mechanical this link might be of some use

You need to change fork seals and fork oil, the dirt/expanded rubber on the caliper is all because the fork oil pumped out all over it.
Thank you for pointing this out for me. I went to several of the links within the thread there and understand how to disassemble the cluster. I am not sure yet how I would compensate or correct for my speedometer error though.
It is on the ever growing list of things to do. Thanks you for identifying why the caliper looks like it does!
On a bright note, my forward brake lever now activates the brake light. I do not know why it started working again, but it does.
I went back to relook at several other thread and see where I made the mistake on thinking my tank is bigger. I also see where some have used the tank from XS750s and 850s to get more fuel. While I like the look of this little OEM tank, I'd like to know what bigger sized tanks will fit the bike. I'd like to get up to 5 gallons if there is one out there. Any options readily available?
By far the easiest is a tank from an XS650 standard. gives the 3.9 and a realistic 150 to 180 mile range. Far further than (most of our) butt range.
Scrap the XS850 idea, it has a double backbone and will not fit the XS650. XS750 tanks require some fitting and also a custom seat. @gggGary provides the simplest solution. You only have to block the right petcock mount hole. Personally, I like the Special the way it is. If it's inappropriate, I think replacing it with something that is, is a better option. A friend of mine extensively modified an Eleven Special for touring at great effort and expense. Eventually, he replaced it with a BMW and no one wants the modified 11 Special.
Buzzy is getting 39 mpg now. That us up roughly 5 mpg since I got him.
The wind was quite strong on the way home and in my face. Wind was right at 20mph with gusts around 30 to 35 mph. When one hit, Buzzy would lose about 8 to 10 mph instantly. It's been awhile since I've had a bike that takes a hit like that. And I know the windscreen accounts for most of that slow down. Still, it only tool a little throttle to recover each time

XS650
Special Tanks take 12.5 liters
standard tanks take 15liters
XS750
Standard tanks take 17.5 liter's............If you get the tunnel of the tank from the XS750 tunnel made to an XS650 tunnel it will increase to 22liters.
XS850
get the Euro/Oceania XS850 tank and it is already 22liters and changing the tunnel to an XS650 will give you a 27liter tank.
You need to find out why your bike is getting such poor mileage. Keep this up and the excess fuel can damage the bores due to washing off the lube

From comment #180. Boog said.... "I mentioned earlier that at 4,900 RPM, the speedometer says I am around 60mph, yet Pretty pillion says her car's reads 70 or so."
If the odometer is also off that much (likely) and Boog is basing his mileage calculation on that... 60 miles indicated would actually be 70 miles traveled. I'm too lazy to do math tonight
but I'd guess his 70mph "buzz" down the freeway is actually gettin' him about 45mpg. That ain't bad.
And that may very well be the bottom line. I had not thought of that. If my mileage on this last tank were adjusted to 76 miles vice 66, then the 1.7 gallons is 44ish mpg.From comment #180.

44.7 to be exact. We can round up to 45 jus' so I can say I was right....
After thinking about it, I'm not so sure the odo will be off along with the speedo. 
Trying to remember what the inside of a speedo looks like.
Sorry Boog, but the more I think about it, the odo is likely correct.

Odo is gear driven, speedo needle gets influenced by a spinning magnet.
If the front tire is stock size odo is usually right, or wildly wrong, as in stopped or skipping 10 or 100 miles at a time.
