Default Couple of Questions

Just a couple of questions: 1. What kind of gas mileage should I expect with my 2012 Vision? I know this depends on riding style etc, but I ride like the old man I am at 70. 400 miles on the bike so far and getting around 38 mpg.

2. This bike has an occasional backfire when letting off the gas. I talked to a guy that has an 08 Vision, and he said that Visions are notorious for this.

Any input greatly appreciated.

I get around 42 or 43 mpg on my 08. I add better performance exhaust and Lloydz timing wheel set at +4. I don't go into 6th gear till over 65 mph. Not sure when your shifting but that could be your problem. By the way I put in new spark plugs NGK every year from auto store p/n 3481.

thats good mileage for a big heavy v twin
mine gets 14 kms per litre or 32 USMPG, but mines hot rodded and I ride it.
maybe 16 kpl cruising thats 37USMPG

By definition a backfire is firing back through the intake.
but its commonly mis-termed for a pop or bang out the exhaust, just a bit of unburnt fuel exploding in the exhaust, usually amplified by a hotrod exhaust system.
mine makes a loud Crack occasionally and snap crackle pops on decel.
sounds pretty cool hey!

Sounds about right.

I have a 08 and 13 and get 36-42 on the bike computers regularly. You can see my mods below which I'm sure has helped but I can be a bit aggressive. If I was able to behave I could probably start over 40..... But that's hard to do.

Yours stock?

Yes mine is stock, as far as I know. Trying to determine if it has aftermarket exhaust.

Unless you have a nice rumble and the heat shield are being held on with regular hose clamps they're probably stock.

The stock shield straps will be solid and pressure locked to secure them. When you cut them off to change the exhaust the SOP is to use hose clamps which will be slotted and tightened with a screw.

Yes, the backfire is normal for the Freedom engine which is what you have, it's all about how the engine breathes and unburned fuel, as MBX said collecting in the exhaust that will light off. It's not normally a really loud backfire but it does happen during city type riding with a lot of up and down shifts. I learned to ignore it long ago; I imagine you will too.

Is this 47 mpg what the bike display reports or determined by your own calculations of miles driven divided by fuel quantity used?

Roy, I'm 80 and ride like one of my kids. The "backfire" is really exhaust popping or decel popping usually caused by shutting the throttle too quickly. Minimal throttle movement = minimal popping. No need to close the throttle between shifts - move it as little as possible.
Don't lug the engine. Yeah, its a torque monster, but it likes revs and you'll like the better mileage. Don't go into 2nd until you're over 20, 3rd over 30, etc. Don't ride under 2500 rpm. I don't put 'er in 6th until 70+ mph. I get high 40s to low 50s or better with the mods you see in my sig.
Now go out there and flog it Roy!
