Skins made a remark in the Idle Noise forum about how his Dellorto's are a fuel hungry pair.

What carbs do you have and What mileage do you get?

I just did 300 miles 2 up. We were not ringing the old gals neck. I averaged 45 MPG and have Dellorto (36's) carbs.

I'm not whinging about the cost of fuel here, just trying to discover what others have for fuel use. It's a measure of tuning and setup.

Mikuni flat slides, I think they are 38s but may be 40's. Whatever, I think they are too big.

Gets about 30/31 mpg solo.

My pazzo Paso still has the infamous Weber, albeit significantly re-jetted (165 mains). I've had casual tours on which it returned about 48 mpg, and on more "enthusiatic" jaunts through the Berkshires I still get about 40 mpg.

I have taken my Paso on a few long runs since fitting tghe GT750 Mikunis and the average seems to be around 45mpg. Which is a vast improvement over the Weber apart from the obvious advantages the bike is a lot more efficient.

I've never actually measured the fuel consumption, Jon, but I'll do so now. It'll take a few days.

I just know it'll be bad. Which is in some way to be expected I suppose, seeing as basically all I do is race around the city and suburbs. It did seem to be a little better when I did a 1000-mile trip up north a few years ago. It doesn't seem to be running rich, when I've looked at the plugs, and when I peeked at the pistons prior to that trip up north. It really just feels good, like it just wants to GO. I reckon those Italian carbs are just naturally uninhibited, and the motor just wants to go with them.

Hey! We're nearly neighbors. I'm over near Poughkeepsie. We have quite a few members from CT in our local club http://www.desmoducati.org

My Paso have mikunis from 600 monster, with main jets 150 and 1.6 mm washers under the needles. Very noisy KN cylindrics filters (RU-0800 model).She drinks 8 l/100 km.
You will have to translate... Why an Italian bike must use always miles, gallons, gauge(for wiring)!!!

Well, 8 liters is close to 2 gallons. and 100K is about 62 miles. in the 32 miles to the gallon range.

8 L = 2.113 gal
100 Km = 62.137 mi

29.408 mpg

You wouldn't be an engineer would ya???

:-)

They call me a process engineer at work. Just an ole COBOL programmer who knows enough about MS Excel to be dangerous.

At last I have managed to clock up 100km (102.2 to be exact) since I filled the tank to a measured mark. It took maybe a dozen outings, all but one of them short trips into the city (about 6km there and back) usually giving her heaps, lapping up that torque at low revs (making the most of my rare minutes to myself) hardly ever going higher than third gear, and the temp gauge barely coming off the stop (it's cold here now). Today I managed a trip of 22km, where I rode gently to make up for all the dashing about.

She used only 6.45 litres! So I got about 40mpg, I think (can't be bothered working it out exactly) and I'm very pleased. I shouldn't have thought to badly of those good Italian carbs.

For those of us in the UK I'd just remind you that a US gallon is 4/5 of a UK gallon, so 40mpg in the US equates to 45mpg in the UK.

er, thanks, I think, speedtrifle ... I can feel a state of confusion setting in (I am mathematically challenged). As you see, in Kiwiland we are now in litres. I have no idea whether we used to be in US gallons, or UK gallons, or whether it makes a difference to my current situation. Oh dear ...

US / UK or NZ Gallons thats not bad fuel consumption there Skins mate. I think mine runs about the same on my Webbers.
