Fuel economy.

Just throwing a general question out there to everyone.

What kind of fuel economy are you guys getting?

I worked mine out on a recent trip I took. About 50% town driving and 50% highway (between 60mph and 80mph).

This is in a 1600 R series with a 4 speed.

For this trip I worked it out as:
8.67 liters/100 km or in the old money 27.13 miles/gallon(US)

How does this compare with what you guys normally get?

When I was driving long distance to work, it was a balance between mileage and driveability. Lean the solexs out too much and deal with mid bog. My best was 23 mpg in the summer and 24 in the winter with strictly hiway miles. Once got 13 mpg in a testing spree!

1600/4 speed
27 mpg on regular unleaded (87 octane)
31 mpg on supreme unleaded (90 octane)

i always thought fuel economy would drop with higher octane ratings...

anyhow, i get about 26 - 28 with a 1600 / 4speed.

This question is routinely asked here and on the mailing list. IIRC, the range on a 1600 is 13-35 mpg with the average being 25-27mpg.

Hmmmm.

Let see one lap equals 2.9 miles 12 laps per session so thats about 35 miles give a tenth uses 5 gallons out of the eight gallon cap. on the fuel cell. Yep that equals 7 mpg thirsty little devil.

I have gotten as high as 33 on the freeway, and as low as 5 around town. I just installed 37mm venturis and new jets however. With the venturis, it seemed about the same, with the new 165 main fuels and 65 pilots, it seems a little thursty, but I havent gone anywhere with it either so its hard to tell.

SLOroadster:

Ok just talking back to basics here. Seeing I just got mine back on the road after god knows how long it's been in various workshops/garages around the place over how many years. Mine's a complete stocker mechanically, and what I'm trying to return it to aesthetically - difficult in Australia.

27 odd MPG sounds great from my point of view considering I've been working toward getting a relatively 'normal' roadster back on deck.

Good to hear I'm in the ballpark anyway. At the back of my mind I was hoping for a little better economy, but surely that's influenced by the insane fuel prices we're being hit with downunder. Can't complain though I get worse mileage outta my motorbike!
