MPG on a 1978 Gl1000

Post by jazza »



Curious as to what MPG people are getting out of their 1978 GL1000.

I bought this one about a month ago and have been working on it ever since. Wouldn't crank at first and popping something awfull when I did it it cranked over. Have it going and running quite nice now and am loving the ride. Flushed out and replaced all the fluids except brakes and forks. Ran some carb cleaner through it on the first tank of new gas.

This is my second tank of gas and I am only getting 24MPG to and from work. Should I be getting better than that? I would think so!

Never going over 40 miles/hr and accelerating very slowly. Only traveling 6 miles to and from home.

I warm the bike up for about 2 mins before riding. It has the full vetter kit with windjammer on it.

Should I be getting better gas mileage or do I have a few factors going against me?

Still have to replace the air filter, I think this will help a little...spark plugs look ok but I may replace those.

Any other suggestions to increase my mileage?

my 76 gl1000 would get 36 mpg.Well,that's downhill with a tailwind.I was never really impressed with the economy.I guess it would average 22-30 on any given day.A close inspection of the plugs will tell more about the running condition of the engine.If their sooty,it' got more fuel than it can burn.After a hundred miles or two,pull each plug,your looking for a light tan tip.not black or white.Check each plug.I did find one of mine was running very rich,sooty(syncing fixed that).

The whole time you warm up a bike it is burning fuel and not racking up miles , but it should be done.
Just food for thought

I just averaged out my miles on my 76. This is after only one tank of gas and I plan to do about 5 before I decide my actual MPG's. But I got 26 MPG. We own a Honda Reflex scooter that is pretty cool and does 70. That Bike gets 70-80MPG's but I look so much cooler on the GL1000!!! LOL!

I bought a old 78 mercedes and fixed it up to drive.One day someone asked what kind of mileage I get.
You know,after driving it around,I really didn't care.I was driving a mercedes.I was happy,that's what mattered.
Oh,by the way I checked,It got 21 mpg.

I'll check the plugs.
Warming up the bike makes it run so much better and I'd hate to blow the gasket.

Totally right Virgilmobile...I love the bike I really don't care about mileage but it's nice to know.

The 78/79 should average around 40mpg plus. To get an accurate reading you will need to ride for an extended period. Riding 3 miles one way and with warming up for 2 minutes you are not going to get very good mileage. Actually it is not even going to warm up the engine properly for good combustion. If I were you I would take the long way to and from work. More fun anyway. :lol:

The only problem with taking the long way to work is making that turn into the parking lot at work.. ;)

Halfway through this tank of gas I changed the air filter and gas filter....Gas mileage jumped from 24 to 33 mpg. will be interested what I get this next tank since the new filters will be on there the whole time. Should jump to about 40mpg I think.

I ran my scooter up to Las Vegas from Phoenix last weekend running 70-80mph the whole way and managed between 36-39mpg. Clutch was slipping a bit and it really bad now. Gonna have to get that worked on..

I'm thinkin if I ran around 60-65, it's pull over 40mpg..

I completely concur! I routinely average 38-40 mpg. Though my 1978 GL1000 now has 19,000 miles on it, when I bought it two years ago (with 15,000 miles), I shipped my entire Carb set up to Pistol Pete's and had them do their "rebuild & sync" magic on it. That, combined with adjusting my valves, and adding 24 oz of Marvel Mystery Oil to the 2 qts-22 oz of ATV 10W-40 oil on my last oil change, has this vintage Goldwing running in tip-top shape.

My 77 has averaged 45mpg for over 200K. I've seen it in the 30's and 50's. I don't think I could get the mileage down in the 20's no matter how I rode.
