My stock 700S averages 33mpg overall.  Best ever has been 54mpg on a straight highway run.  32mpg doesn't seem that far out of spec.

Just checked yesterday at fill-up with no highway/mixed backroad and city and was at 33mpg. I have never had the chance to get on the highway. Good to know about stock mixed MPG, thanks.

Man, I'm glad the mileage on my 700s is better than that. My 2 year average from my app is 42.96 mpg. My worst in the last 2 years is 38.99 mpg.

My '96 has a 17 tooth front (stock is 15) and stock sized 38 rear sprocket both of which were changed when it was time for a new chain.

Was a 112-link chain (110 is stock) long enough for the 17-t sprocket install?
Howdy..
No, the stock size is too short (not a big surprise, the front sprocket is 2 teeth bigger).
You should get an extra master link (2 instead of one) when you buy your chain, because the 122 is a bit long, and you won't have much adjustment left.
After several thousand when the chain is stretched a bit (or when you run out of adjustment space), remove the original master and one adjacent link and install the new master you wisely purchased earlier (so you now have a "stretched" 120) and you're good. 
It's a little bit of a pain, but if you have a decent set of chain tools, it isn't a difficult job, and you don't have to remove the chain twice to do it.

If you do a lot of interstate, it is well worth it.  If you are mainly a city driver, probably not.
The way you get improved mileage is by the engine not working so hard at a given ground speed.
Where I live, the speed limit is 75, so my bike spends a lot of time as a fast mover.

In the interest of full disclosure, instead of a roll on for passing, you need to downshift to get the bike into the powerband..
With the mod described, 4th gear is like 5th in the stock configuration.
You'll get better mileage because you are turning fewer revs, but of course that means the engine is producing less power.
That's how you get the big mileage bump - there's a big difference between 4K and 5K on the tach.

One other advantage is that the larger front is a bit easier on the chain, as it gets less "pinch" up front.

Keep the rubber on the bottom!

I started out with the  LEDs that you see in the first pic. They are from Bikemaster as well. They looked good, but I just couldn't get them right. So I opted for the ones pictured. They are much better installing. It's basicly plug and play, as well as the mirrors.  My rear signals will be here today and I will take some after pics.

How do you like the Corbin seat? There was one for sale in Ohio, but the add disappeared on C/L. He advertised it as being BIG in the saddle and for a bigger person.  I messaged him and he never got back with me, I'm not a bigger guy, just wanted the seat..oh well

FYI, I keep track of mileage for all my vehicles using fuelly.com
Easy to use even on a phone, and you can enter/edit entries at any time as well as compare to others' vehicles.
