850 Eldorado highway mileage

[Canuck750]

I have never figured out the fuel mileage of my 1972 Eldorado 850 until today, all stock motor / carbs, MG Cycle flat slab windscreen, solo rider 190 lbs. moderate wind, highway average speed 65 ~ 70 mph. Over a distance of 700 km / 435 miles my fuel consumption is 51 miles per Imperial gallon / 42 miles per US gallon.

How does that compare to similar Loops?

  It compares quite similarly to my Le Mans 2 .  Peter

I haven't done a lot of long trips on the loop and my fills are in recorded in litres
I dont have a windscreen and my fat arse weighs in at over 220ib and weighed down with camping equipment
one 680 mile trip I added 73.66L which divided by 3.8 is 19.3842 US gallons
It worked out at 35.08 miles per US gallon, i'm ok with that.
Its such a loverly old bike to ride I really can't think why I dont do more longer trips.

Can't give a comparison, but that seems pretty darned good...

For your bike and speed you were doing, about 40mpg would be about right. That's what my Eldo and Ambo would get.

Thanks for the reply’s, I thought it was pretty good for a carbureted 50 year old bike, 1/2 the mileage is crossing the Rockies between Alberta and B.C. Up the Bow Summit and Roger’s Pass. Not as comfortable or as quick as my modern BMW, but probably better gas mileage and a much bigger smile on my face. I gotta ride this Loop more often!

I dont have a screen on my big bore Eldo and get around 53 to 54 imperial MPG but my bike gets an easy life and is never pushed too hard

I'm getting 45-50 mpg with my '72 Eldo.  The bike has Millennium re-worked cylinders that were opened up to around 900cc of total displacement, CP-Carrillo pistons, carbs jetted to 50/150 and stock everything else (heads, cam, air filter, exhaust, etc.).  Initial timing is 5° btdc and full advance is 38° if I recall and whatever advance springs were recommeded by Dave Richard's Guzziology.  The farthest I've gone on this bike is about 400 miles round trip and no higher than 1500'msl.  And, I'm running 87 octane unleaded fuel (with up to 10% low btu filler...lol).  No windshield.  What else can I say?

54-55 MPG (imperial gallon) from one of my V700s @ 70 MPH  on regular octane fuel.  DonG

Good thread, still most people have no records or even thought of consumption, despite price rise that they moan about.
To me it is icing on cake, build an engine, tune as best I can without dyno or afr meter. MPG tells me if I won or lost
V700 (big 83mm bore so 757cc) 5c hole mufflers, phbh 30’s, 8/33 gearing, no windscreen nor respect for speed limits
Generally around 4Krpm but pulls from 2 stops at 6
No highway droning, ever, quite a few multi day trips and  regular shopping miles
Best 23km/ltr (65 proper mpg) Worst (keeping son on modern Ducati honest) 19.5 km/ltr ( 55mpg)

If ever needs be, 70mpg is doable imho, keeping to our local speed limit (62mph) and never holding people up. But that will be a boring day
Anyone here ever do test on loopy at 55mph when that was enforced in US?

Those figures echo mine from my recent cross-Canada trip. A comfortable 200 miles per tank with a bit to spare.

Good luck on your trip Jim

Last summer's ride on my 73 Eldo from the middle of Maryland to Meadows of Dan, VA (SW Virginia) - no interstates, mixture of 4 & 2-lane US routes for the most part, some Blue Ridge Pkwy & going thru a few towns, I got 58+ mpg on a 3-day 700+ mile trip.  Almost all the highway riding was at 60 - 65 mph and the stretches on the BRP were generally at around 50 mph.  After I got home & calculated my gas mileage, I immediately checked my sparkplugs because I thought I must have been running the engine way too lean - turns out that the plugs reflected maybe just on the overly rich side of "normal".  I'm about 165 lbs fully geared up & the bike has a "European style police windshield" so I'm a bit lighter than many riders, but the bike is much more fuel-efficient than I expected, especially with a windshield.  I think one of my riding partners on his Convert got about 35 mpg or so and the other rider, on his Eldo, didn't keep track of his mileage.

I'm a "smell the roses" kind of rider who enjoys watching the scenery more than just looking at the road ahead of me & calculating how fast I can get through each turn of the road or how many people I can pass - not a criticism of riders who have a greater "need for speed" than I do!

My '73 Eldo with a Vetter used to get low 40's to 50 mpg.  It didn't seem to vary so much by speed but more by whim....

40 mpg - I've never dropped into the 30s except when I ran Valvoline VR1 20w50 for a short while.
