Ok what are you getting for mileage with your commando.

My 72 Combat had a 19T but My 74 has a 21T Sorry I have more than One Norton Commando.
the 19T accelerated like crazy. But for cruising at 70 Mph it puts you up the rev range and your mileage will be less. Esturaryboy...Sorry you may not have read the entire thread?
Two different types of riding.
If I am reading you right?
Yes.. I started reading when you reignited this at post #45, then picked up on the subsequent mention of a 19t sprocket at #73.....
I put two and two together and ran out of fingers :-(
 
Hi Dereck - please warn me before you do a long strip again....


Hi Ian, Should I carry some extra gas for you.

I took some time to get those carbs right but they are a bit lean for the first 1/2 minute after starting, especially as I don't have chokes. Runs well when it's warm.

Not with his fat tank!
 
Had my worst mpg the other day 82 miles before I ran onto reserve
There's a big drop in mpg between sustained 80mph and 90mph I have found

Fuel consumption increases exponentially with power output / speed.

I had an 850cc Triumph Twin racer and once calculated after a weekends racing that it had achieved 12 mpg.

Best not to mention this to Greta…

Yep I knew it did increase but I hadn't realised just how much and since this thread started I've been paying more attention to the mpg
I've been reseting the trip each fill up
On my t160 fitted with 28mm VMs I once got over 50mpg riding back from a weekend away at 55mph because I had self induced headache!!

baz,
Absolutely, to what you say is true. It all depends how hard you ride it or who you ride with, which dictates your MPG average. So my recommendation is when you are on reserve, bring it down to below 70 unless you know where that next fuel station is located. That will get you the best MPG. I have also had crap gas at stations that may or may not have been ethanol free on premium. I always try to select premium fuel and Shell is my first choice in Canukland.
Cheers,
Tom

Greta wants to say "how dare you" with that scowling face! Brainwashed by her parents and the Global warming crowd. No one says a peep about China....Oh I said too much already. No politix here!
Have fun around the track. But tell us what track to get your MPG average. Number of laps. I'm all for it.
Cheers,
Tom

750 non-combat, twin 32mm amals: 50 mpg
650 Triumph, single 32mm amal: 65 mpg

The single carb works really well on the Triumph, so I converted the Norton to a single 32mm amal for a while, it ran silky smooth, but strangled the upper rev range, so now I'm back to twin carbs.
