Yep! I did it! Thought I would start yet another thread on gas mileage due to the rising prices of fuel. (Plus, I know you guys wont bash me like they will on some other forums Im a member of! LOL)

I filled up this morning and gas is now at $3.39 a gallon. Took $11.00 to fill up!

Anyway, I have been trying to make myself ease off the throttle and break the 40 mpg threshold on the Hurricane, but just cant quite do it. Todays fill up came to 39.9 mpg. Getting close, but just cant get it! Im not going to hypermile extremes though as I have seen some folks do.

Bike is one tooth down in the front and jetted.

I am determined not to be a victim of rising fuel costs! Today it's supposed to rain and I still did not cage to work. Threw the rainsuit in the saddle bag and jumped on the Hurricane.

 

My '87 gets 40-44 mpg on extended 70-75 mph rides. Bike has nearly 58k miles. If I were to do the posted speed of 65 mph I would wager I could get close to 50 mpg.

 

I run 87 oct. and get 42-44mpg on my daily commute of 42 miles each way. Roads are 60% back roads, 40% interstate. Stock gearing, Dynojet kit, K&N air filter in the stock air box, snorkle extentions on the air box removed, V&H SS2R system, V&H PowerPack ignition box on sport setting, NGK Irridium plugs. And I don't spare the horses when I can get away with it.

 

That's really good gas mileage Neal. Im not sure why mine doesnt do as well on mileage. I dont think the sprocket on mine would make much difference with my riding. But I know it usually gets a few mpg less with winter blend gas.

 

bicklebock,
I forgot to mention that when I first rejetted I opened up the the pilot screws 1/4 turn. Don't ask why. I was young(er) and didn't know better. The bike was harder starting when hot, didn't require muck choke if any and milage was horrible, 36-38mpg. The bike was just not as much fun as it should have been. As a result it sat for a few years in the garage. When gas prices spiked a few years ago I HAD to get the beast back on the road.
I went through the carbs. Cleaned the jets. I also reset the pilot screws to the stock setting. What a difference!
Lesson- my driving experience and MPG's are very sensitive to pilot srew settings.
No, I didn't follow the proceedure for setting the pilot screws. I used the standard settings referenced in my US shop manuel which is slightly different than the one posted on this site.

 

Interesting Bassman. I have never done anything to my carbs and I have putting it off. But it runs and starts fine, hot or cold. Maybe it's time i man up and get into the carbs!

 

If you want to get the best gas mileage search for gas stations that still sell 100% gas. Not only will your bike run better you will get better mpg. Gas with ethanol hurts performance and gas mileage.

 

HI,just want to know why you removed the snorkle extentions.This is not the first time
I`ve read this,but have not understood why since Honda and other manufactures use this system and they invest in a lot of time and money to design a bike to have optimized performance.

 

$3.39? Thats cheap where I live... I don't think regular 87 is even that low.

Im paying around $3.75 for premium right now

 

with the big 18 on the front and a 44 rear I "can" run 48 - 50 on the highway
takes a hell of a lot of effort to do it though at the risk of falling asleep

$3.29 the cheapest near here over the line in the Live Free or Die State
