I thought I had heard about this somewhere,but can't seem to find it now.

Is it possible to drill a hole or two in the filler neck so the gas fills up faster?

I'm usually sitting there, putting a few ounces in, then letting it settle, then a few more ounce, and so on.  It takes me just as much time to fill as a big SUV, and I'm only putting in about 3 gallons. 

Is this safe, or would it even work?  I'd love to do it this weekend if its a viable mod.  Could save me tons of time at the gas station.

Btw, the bike is a 96.  I think they fixed the problem with the new models, so it may only affect us poor guys with the bikes from the 90's.

Anyways, give links or other knowledgeable info, so I can figure out what I need to do.

Thanks!

I think it is how you are using the gas pump.

I hold the nozzle so it is just in the opening then let it fill up.
When it gets close to the bottom of the fill tube, I slow down so it doesn't splash out. Goes real fast.

If the nozzle has one of those California type vapor thingies, you have to pull it back with your hand so it thinks you've stuck the nozzle into the gas tank. Those things are not designed for filling up motorcycles.

How are you doing it?

the ones here in oregon i have to pull back as well, i usually hold is diagonally so i can see the fuel tank being filled

If you are plunging the nozzle into the tank you are doing it wrong.

As has been said... hold it so you can see the tip of the nozzle in the neck sleeve thing. It will fill fast right up until the bottom of that. At this point you can then stop, take the price to the next 50 cents or dollar, or go very slow and squeeze another quart in or two.

I understand what your talking about, try a piece of copper tubing formed into a "U" but one side longer (handle), put it down the filler neck then have the short end come up the other side of the filler neck to the top of the tank...better than drilling and it will let you try out your idea??

The way i do it, is I stick it in a couple inches, and have to pull the vapor sleeve back.  It fills up fast until the bottom of the filler neck.  At that point, i can usually fit another 3/4 to a full gallon.  I usually  put in around 2.75-3 gallons on a fill up.  And it is usually right around the time that I have to switch to reserve.

Anyways.  From the point the gas touches the bottom of the filler neck, it takes forever!  I can put in about half a cup of fuel, then have to wait a few seconds for it to even out within the tank, and the level in the neck goes down.  It usually takes about 3-5 minutes to get that last gallon in.  I don't know why, other than the air has no place to go, and the fuel needs to displace it.   That's why I was thinking a hole near the top of the filler neck would let the air escape, and allow the fuel to level out quickly.

Using a tube like was mentioned would be a good way to see if my theory works I guess.

My bike is old, and worn, and I don't drive more than 3-4 miles at a time to and from work.  So I usually get about 37 mpg, and a little over 100 miles on a tank.  I like to get as much as possible in the tank, so i dont have to fill up so often.

There has got to be some reason why my tank takes so long.  Is there supposed to be a vent or something in the top of the tank?  Maybe mine is plugged?

I actually just found a small vent hole, exactly like what I was think about making.  It is very small though, and just may not be large enough to let the air come through all that fast.  It was slightly up under the lip on the right side of the bike on the filler neck.  I threaded a piece of fishing line trough it, and it does just go straight into the rest of the tank.  I also could see light through it when I shown a flashlight into the tank.  So, either making that one hole bigger, or making a second or third hole in a similar place would probably get the job done.  And since here is already a hole there, then I'm not so worried about any adverse affects.

Now, any ideas on how I could drill a hole, or expand the hole without getting metal shavings in the tank?

I live in california.
Normally, when filling a car, you situate the nozzle in the filler thing on the side of your car, then push in a bit more so the sleevie thing can tell you've got it close to the filler, and then go.  You dont technically have to make it "seal", to make it work.

Now with my bike;
Technically, I can, after MUCH wiggling, get the spout in, and also the vapor recovery actually "inside" the circle for the gas tank cover, and fill up. It actually "seals" that way.
But its way too much of a pain to get in and out (wiggling it under the edge of the gas tank cover)

Instead, I just rest the edge of the sleeve, on the OUTER metal ring of the tank, and apply downward pressure on the thing, so it stays engaged.
Works fine.... auto-shutoff works fine, and it only takes a minute or so to fill up the tank.
Fast, easy, and consistent level every time. (when I go to the same gas station, anyway)

If I really wanted maximum fill, I'd put it on the centerstand... but nope, I just fill on the sidestand. Then I refuel after 120 miles, which to me, is 3 days of commute.

When fueling I use the center stand and rock the bike back and forth on it (gingerly) once the tank is full, this burps the tank and lets me maximize my range by letting me squeeze a bit more in the tank.

the collar is there for a reason, to allow for expansion of the fuel.  if not the fuel will expand and overflow.

True, but you can fill them to the top while out on a ride as long as you get right back on the bike and hit the road, you don't want to fill it to the top with a hot engine, park the bike in the sun, then go in and have lunch
