I'm a new rider with a 2010 C5, just breaking it in. I've ridden about 800 miles, mostly in city traffic below 40mph with a lot of stop-and-go, some intermittent short stretches of highway. Almost all my riding has been in New York City.

The best I've achieved is about 42 MPG (US). Is this normal? Should I be expecting better?

For what it's worth, I'm a heavy person (250 lbs).

My shifting technique is probably fine - I have 30 years experience driving a manual transmission car.

I doubt whether weight would have such an effect. With pillion still averaging 65 mpg and more from adjusting riding style.

Over 10,000 miles the mileage is 62 mpg. Monthly averages vary from 56-75 mpg. 68 mpg is common. Mostly stop and go traffic, probably a tat more fluid than NYC but still not ideal conditions. Best average was the breaking in period (75 mpg). With a more sedate style results would be even better.

Do try some rides of 200 miles on country roads, away from city traffic. See what average you make then. That would give a better idea of the bike's normal fuel usage.

I'm guessing your exhaust pipe seal (at the head) is leaking. 

in between exhaust pulses, a leaking flange gasket will allow fresh air to be drawn into the pipe.  The O2 sensor will saturate, and, your computer will drive the mixture overly-rich in an attempt to balance the O2 signal.

the above discussion assumes your machine is running well, and, the MIL is not illuminated.

I have a 2011 G5 . When new I would get around 55-60 gallon whilst running-in.  This improved to mid 60s after. Now having upped the front sprocket to 18 tooth and changed the OEM silencer to an Indian short bottle + a K&N air filter I am up over 70 to the US gallon. My riding is a mix of stop/go surface streets and 65-70 mph freeway on my commute to work (13 miles) mid 70s if I stay on the freeway longer. I only scale around 180 lbs geared-up.  So anything under 50 mpg (US) sounds rather rich.  Would have the dealer check it out.

In the last 11,000 miles that I rode for a total of 16,000 miles,  I averaged 69.58 MPG I could easily average over 70 out on the country roads or in the mountains (Over 75 above 5000'). On the freeway cruising 65-70, the mileage would drop to about 65 mpg. 2011 G5 with 18T sprocket, EFI Exhaust, K&N Filter.
I weigh about 190 suited up.

It had over 4000 miles on it before I started keeping mileage records. However, my first tank of gas on a very slow breakin run yielded 80 mpg. I've had several tanks that got well over 75, usually in the mountains.

I stay over in the truck lanes and try to hold about 62. Gets a lot better mileage! If I stay at 70, my mileage will drop to about 62 mpg.

Well, I hit 54 MPG on the last tank, which was about two-thirds highway (NYC highway, meaning 55mph and some intermittent stop-and-go between the open stretches). This weekend I'll do an all-highway tank and see if things get even better.

See, getting better already  ;D

And once the trees start budding you'll be in the ballpark, hitting homeruns all the time. Cheers!

OK, I'm not concerned any longer. I did a hundred-mile tank today that was mostly NYC-area highway (meaning: average speed while on highway about 50mph) and got 63mpg (US). So the bike's capable of performing as advertised if I'm not constantly having to shift and slow.

Route: A loop from lower Manhattan to Jones Beach and back, followed by a loop from lower Manhattan to Staten Island to Bayonne and back. I'll write the trip up on another thread.

working on 4.5 litres to the imperial gallon i get 98 mpg on highway running at 55 to 60 miles per hour.
as for around town running - never done that - too dangerous riding around town so it's the highway or nothing

Fantastic result!
I only got that one over the initial weeks, basically the break-in period. But without going over 50mph. So, does it count?

Ever since I consider a result of plus 85mpg (71mpg-us) as a succes. Which occurs, at times, on long hauls, but never over 90mpg.

I've got a 2012 B5 with 3,333.3 and I usually get 60 or just below. My average freeway commute is 10 miles there and back again with a top speed of 70, but usually 65. Sadly, I weigh in at 195 and can't seem to lose more.  :P
