mpg

Postby m2102 » Thu Aug 02, 2012 8:24 am



recently changed plugs in my wing and all went smother than could have hoped for,even found a couple tools while in there. my queation is,before changing them,i was getting in the high 38 to almost 40 mpg.after changing i am getting high 36 to mid 37 mpg. idol is same as before runs like a clock but have noticed a slite static noise in my headset,with or without blutooth on. i used ngk stanard dpr7ea-9 plugs,gap was what it called for tightened by feel from when i took them out,no torq wrench for inch lbs. any suggestions what to look for?

Could be that as plugs wore and gap got larger it caused a lean condition that resulted in higher fuel milage.

that could be the case. i did check a couple of the old ones i took out and the gap felt same as the ones i put in.probably could have left in the old ones but didn't no how old they were.apperance wise didn't look that bad.mite in a few weeks take them out and check them for gap and if getting "dirty"

What plugs did you take? maybe have been resistor plugs usually an "R" in the ID which help to stop buzz in radio's etc. Also depending on which way the open gap faces your plugs work better..maybe the old ones all faced toward the piston center and the new ones don't. There are ways to known..mark the plugs and install or adjust the firing tap by cutting a bit off so it fires dead center rather than to one side. An old racing tech tip. There are threads about how to do it here and there on these forums. NWG for sure.

I have seen an increase in radio noise with spark plug wires becoming worn. as they age you get higher resistance and more noise and weaker spark. One way to find out is on a damp evening with the bike outside (in the dark) fire it up and look for stray spark around the engine. You could even spray water around the engine while it is running .Good luck.

that is fantastic,do you have a secret or do you have a blessed wing. i've heard of others gettinng high 40's but use some additives.
some claim twc3 2 cycle oil works,tried it but not that much of a difference.also heard that straight gas without all the stuff in it works for performance butnot available everywere. have an outlet that sells it but haven't tried it.

I use 91 octane and have done so since I got the bike.

Oops I just realized that I use imperial gallons which are bigger than US gallons ....... don't ask me why but they are.

In NZ we use litres ........ confusing eh!

I run 100% pure gas and get mid 40's mpg. About 38 is as low as I remember.

i have heard of the advantages of pure gas.i believe we have a place here that handles,will have to find out for sure wwhere it is and give it a try.only problem is places that have it are few and can be far between

I average around 40mpg. Have gotten as high as 44mpg straight highway at 65 to 70 mph riding solo.
But I really don't check it much anymore. As I enjoy riding it soo much I don't even care what it cost to fill it up.

Good morning bjatwood, what does petrol cost per litre in your neck of the woods. In NZ it is $2.12 (US$1.27) per litre.

Hello Kiwi,
I live right in the middle of the United States, (Nebraska).
We are currently paying 3.59/gallon of 89 octane.
It looks like you are paying ~4.81 for a gallon/3.78 litres.
Ouch!

If I have got this worked out correctly and using US gallons. To fill my tank (6.3 US gallons) at what petrol cost me here in NZ per litre @ $2.12 which equals US$1.71 per litre, will cost me NZ$50.88 which equals US$41.18. for 6.3 US gallons. (24 litres).

Wow. $50 is insane. I usually get about 180 miles before my fuel light comes on, which is when I stop and fill up. It takes 5 gallons to refill for about $18.00 US.

my mileage dropped about 3 mpg lately.not that much but was getting upper 39 even once in a while 40.
could be,and most likely,could be my cbaileys wind shield.pushing a little more air with it.been running 87octane and tcw3 added occasionally. mite try next grade just to see if a difference.once you have a little higher mpg a drop off makes for wanting it back.

Before running off to put high-octane fuel in your wing to boost your mileage or power or anything else (it won't work, despite what the fuel marketing people would have you think), read this: Gas Ain't Gas Any More

I have always used 91 octane rating and the bike just hums along.
