Ran out of gas.

Postby WA9FWT » Sat Sep 15, 2012 10:11 am



I have been wondering how many miles can I put on before I have to turn on the reserve?
Yesterday I put on 147 miles when the egine stopped right at a stop lite.I turned on the reserve and cranked the
engine.It didn't start. I did this several times, still didn't start ?.....I had to push the bike around the corner.Here is where a cell phone comes in handy.

I waited for my brother to come too my aid.Several minutes passed,and then I thought I would try again.I shook
the bike side to side, thinking if I did have some gas left in the tank, it would start. Well it did start just as my brother pulled up. I was off too the gas station in no time :)

Now what did happen.... why did it take that long too fill the carbs ?... So how many miles can you put on before you have to switch over. :o

I'm not 100% up to speed with the 1100 but I imagine it has a vacuum petcock. If you run the carbs dry the only way they will refill with gas is while the engine is cranking and creating a vacuum to allow flow from the petcock.

When I had a CBX you needed to crank for quite some time to fill 6 carbs. I had a bypass tube on the petcock that I could pull a vacuum on by sucking on it.

It takes a fair bit of cranking to get the fuel pump to suck enough fuel from the tank and then fill the 4 carbs enough for it to fire again. I have never had to switch to reserve except when on the hiway at speed, it just sputters and stops accelerating, switch it over and wait several seconds for it to start pulling again. Not fun when you are trying to pass a Semi.

I was getting closer to 200 miles to the main tank running at 60-70 mph, I guess with those training wheels you are running you would get a little less. More weight and more drag. 8-)
Ride safe, Todd

The petcock is manual, and selects between a pair of in-tank fuel pickups, one at the bottom (reserve) and one about a gallon "above" it (main).
If you've run the carbs dry it will certainly take some cranking to get things going, as the fuel pump is designed to pump liquids, not suck air. :D
My experience mirrors Rogues....a sputter at speed, reach down and switch....wait a few seconds, and resume full power.

It's a good idea to exercise the fuel petcock and reserve pickup tube every once in a while, so it doesn't plug up. When you need it, you really need it! On my 40km commute, I use it every tank.

Thanks for all the input guys. I just thought it was strange after the engine quit at the stop lite,and after switching to reserve I could not start it. This has happened too many times to remember over the years that I ran out of gas, but got too thinking that was at hiway speeds, and the engine is still turning.Reach down turn the
petcock,and because the engine is turning the fuel pump is working ,it doesn't take long and the engine fires.

First thought was my reserve wasn't working, :o and thought I was completely out of fuel :?
All this was my own fault,I wanted too see how many miles before I had to turn on the reserve.Now I know.

Horatio took our reserve off the 86s-sure wish i knew why- ive been real nervous a few times but dont know what the gauge says when the carbs are pulling air- always meant to check it out , carrying a gallon can in a saddlebag but running out of gas is known to open cans of worms

Sure is not a good practice to carry a gallon container of fuel.Like you say NO GOOD
One trick I learned a very long time ago when the bike stopped :o out of fuel.Lay the bike down on
it's side, don't remember if I shook it ha ha Then back on it's feet and push the starter.it starts :shock:
I did this more then once.Learned this from a Honda salesmen. Back then we didn't have gauges,just a reserve.
The bike was a 750K honda.

with the amount of cranking needed to refill all 4 my battery wouldnt like that at all i think - i actually go out of my way to not tip this wing on its side shes a beast- i too have wiggled the bike that had 2 petcocks and a "saddle" tank as most non wing bikes are but ill hope i never need to wiggle this wing to extract every last drop
i wasnt going to make a habit out of carrying a legal red can in a saddlebag, i just wondered how far down the needle goes - hey i know- now im wondering if an earlier petcock with reserve would slap right on an '86 ? ooooh ahhhh we gotta reserve?!
ok i just found a fleabay petcock - the owner claims it will fit '81 thru '83- do the '84 - '85 wings have reserve? thanks in advance
edit- 117 petcocks on ebay, half with reserve in the 80s era, no standpipes- apparently the main pipe is integral with the tank and the petcock plugs into it,(o-ring seal) and by design there is at least an inch of gas in the tank when the petcock cant pick up anymore unless the bike is wiggled

One of the first things I do is carry a gallon of gas after a fill up, reset the trip meter and run it out of gas. I'm much more trusting in the gauge now.

its bugging me why a flagship model deleted such a omnipresent thing as a reserve- mom n pop not wanting to ever let the gauge get into the red nonwithstanding- stuff happens for whatever reason and to be sure a wing will drop one cylinder first as your/my warning to flip to reserve-
how about Honda deleted it because their lawyers told them the fossilized people that buy them arent good enough riders to reach down and flip it while riding? i (think) its the only bike on earth sans a reserve and there are many gas gauge equipped bikes

that kills more than one bird with one stone- you discover the bikes current mpg and what the gauge looks like when the motor dies - good idea- i dont know if my bike goes below E- a clean wooden stick check would tell me the actual level for whatever thats worth

I think the "low fuel" light was to indicate that "hey, you're now on reserve." Unfortunately, it's not all that reliable, and the thermistor that drives it is a common failure item.

You could do the modification that virgilmobile and I did: viewtopic.php?f=6&t=11167 - the low fuel light starts to flash when you reach the low level, instead of gradually coming on depending on fuel level and temperature.

I calibrated mine to come on when there is exactly 1 gallon usable remaining. I rigged up the fuel pump to pump out the fuel into a gas can, then I poured exactly one gallon back in. I then adjusted the float switch until it JUST came on. I then repeated the test, running the fuel pump until the low fuel light came on, then measuring what was pumped out after that point. It was exactly one gallon.

So now I know when my light comes on, I've got one gallon remaining. I conservatively estimate I have 30 miles remaining at that point - so as soon as the light comes on, I make it my top priority to find a gas station.

There you go Virgil - build a replacement pre-calibrated float valve switch replacement with flasher, you can make a fortune selling to all the people with bum thermistors!

Today I think I learned some thing ha ha.... Back in sept when I ran out of gas, and the bike seemed to run out of battery juice ?... But hit the switch and it started, has acited the same way several times since.Hit the switch,and just touch it, the engine started. To day I removed the battery to find it was 7/8 empty.
Several times I took a look at the sides of the battery during the summer to see just were the fluid was, and it looked full.I just could not make out the fluid level and thought it was full :o

Been around batteries all these years and can not belive leaving a float charger cooked out all fluids.Going to check the amperage on the one I was using.Made by Peak in China...Model PKCOAF.......0.5AMP DC output
2AMP continuous.

Filled the battery,and put a load test on it.It showed a little on the weak side, but still not bad enough to throw
it out.I guess I can play with it all winter,and see if the float charger will cook out all the juice.I checked the bikes out put and had 13.6 So that seems it is not over charging.
