I some how splash gasoline on my tank when filling-up at the local Shell Gas Sation. I 'm very careful inserting the hose nozzle. and use very light pressure on the nozzle tiigger, but always spray or splash gas on the tank surface. Is there some special technique; are you suppose to place the nozzle hose end some special way into the tank fill hole? At $5.00 a gal. I rather the gas pours into the tank, and not on the ground. Thanks for your help.

I tend to make sure that the end of the nozzle is only just hooked by the end of the filler neck and the angle of the nozzle is such that the flow doesn't hit the central ridge directly.

i seem to have this trouble as well.... and @ $11 a gallon, it NEEDS to be in the tank

A permanent solution is to remove the steel filler neck and drill four or five 5/16" holes midway up the circumference of the metal sidewall. It prevents the airspace above the fuel from being compressed at top-off and forcing any additional fuel back out.

After adding the vent holes, you just insert the fuel nozzle ~1/4" (~6mm) above the floor opening and pull the trigger. The fuel goes in fast and the air comes out fast too. When the level reaches the bottom metal floor of the filler neck you only have to slow the fuel flow a little to just submerge the metal floor of the filler neck. Quicker, fuller filling. No mess. No drama. No wasted gasoline. It also allows overfilling to the height of your holes
-BUT-
you should only do so on the road IF that fill-up is at least 25 miles from your next key off, stop. Overfilling the tank and letting it sit allows thermal/atmospheric changes to push liquid gasoline into the charcoal canister (or to the street after a shadetree mechanic's canasterectomy). The cone shaped venting valve in the fueltank's roof mounted rollover valve does NOT prevent this from happening like it should.

Interesting. Is it possible you're not plugging it in far enough?

I've never had any trouble with my R, and I assumed I would when I saw that baffle just below the filler neck.

I actually stick the nozzle all the way in- it's resting against the tank baffle. It won't splash even on full blast. Maybe I just got lucky this time?

I keep fuel nozzle at the 45 degree angle and about 1/2 inch into the tank.
Just go slow at the end of fueling and use very light pressure on the nozzle trigger.
A while back I was bugging CycleRob for the instructions on how to increase the capacity of a fuel tank.
I followed CycleRob's instructions, for which I am thankful.
Most of the time the idiot light on my bike use to come ON at about 165-167 miles before the modification.
On the last trip to Alabama, I was able to ride my bike for 209 miles before the light came on.
My best mileage on one tank of gas was 231 miles. I think my R1150 can do 250 miles or more, on the modified tank,
but I did not want to take a chances on the road. Now days I am as good as my riding buddies on their RT's, in the refueling intervals.

P.S. Thanks again CycleRob. I wanted to thank you in person at the "Chicken Rally" but could not find you there.

Can you sneak that off the top of the tank with in place? Or does it require removing the tank?

CycleRob, do you know if the European models have all the gubbins connected to the filler neck as we do not have charcoal canisters fitted here? Or will they use the same mechanism to shut off fuel to the vent if tipped over???

Increasing the capacity of the tank sounds great!!! CycleRob could you please elaborate on your method, or direct me towards more detailed instructions. Also how would removing the charcoal filter effect the performance of the bike? I'd love to take that thing off. Any directions on how to make that happen would be helpful.

Overfilling after drilling the vent holes should NOT be a regular routine. There's a good chance the charcoal canister will partially fill up with gasoline if you do not immediately "ride off to burn off" the overfill amount.

Yes, you can remove the filler neck with the tank in place. The rollover valve is attached to it, complicating the hose removal and extraction process. The 2 slender vent/drain hoses need to be removed by correctly squeezing the reusable clamps with a pair of Dykes (wire cutters). A squeeze and a tilt releases them. Study both clamps latching parts up close and you'll figure it out. Mark them before removal so you do NOT mix them up on the reinstall.

I also cut away part of the filler neck side wall creating a wider hole so I could fully insert my manual squeeze/pump's rigid siphon tube as a way of getting fresh gas for the lawn mower. It's visible in the right side of This Pic
There are sharp square edges on the filler neck so be careful about not scratching the paintjob. Using masking or duct tape will protect the local area if you're sometimes clumsy or just plain unlucky.

After removal of the filler neck will the hole be big enough to change the fuel filter without removing the tank? Only joking.....

Hey, why dont you go to UK and pay $11.00 a gallon then when you go home you wont care about spilling a bit

Snowprick: Regarding your sarcastic remark about me paying $5.00 for a gallon for gas and that I should not be concerned about spillage. If my information is correct, you're paying about $1.40 per gal. living in the Philippines. You're the one that should head over to the UK to begin appreciating what you're now paying. Not me. I assume you are so wealthy you don't worry about spilling your cheap gas on the ground and all-over your motorcycle.

My experience of this forum so far has been one of light hearted humour. My remark was not intended as sarcastic. I am sorry you seem to have taken it in that context. FYI gas is also $5.00 a gallon here in the Philippines. Lighten up my friend, this is a fun site.

snowprick: Your immature humor is not imformative, welcoming, or one-bit, appreciated. Apparently you do not do well in group settings. Yes, from time-to-time I have found humorous comments on the forum and smiled, but with sense of understanding and respect for the guy asking for help. You, sir, are just mean.

With that little smiley face at the end I don't see any harm or foul. A sense of humor about the global price of gas is a good idea, as any amount of any other thought process would not be fruitful. As a kid in the 70's I remember TV newscasts of gas lines and 'energy crisis' stuff; it's inevitable that the price will only go up.

Snowprick / Abglenn; you guys were just joking right?

DLS

abglenn, I dont think he was poking fun.. just commenting on the poo gas scenario we're all in. Sometimes humor doesnt come across well, but the little smiley at the end usually indicates that the poster is trying to be funny, or sarcastic... Its ok!

Sorry for my aggressiveness gentlemen towards snowprick. I just have a very low threshold for people who don't take motorcycles as serious as I do. After some 40 years of riding, with no lay downs, I credit my carefull approach and pride in operating my bike the best and safe ways I can. However at 61 years of age, I still feel that I only know 50% percent of what I should know. That's one of the reasons I am a life member of this forum. Also, and as usual, thanks to CycleRob for his expert advice on the fueling problem.

No problem, we're all just one big happy family!

@ Croc ( and others )
The UK version does indeed have the valve gubbins to prevent losing loads of gas if it should tip..
I just looked at removing the filler neck and gubbins ,but the tightness of the clamp on the pipes put me off

Anyway, i thought i'd go with the drilling scenario (to allow the air to escape faster)..


Remove the filler cap torx screws (T25) IIRC
lift and tilt that filler neck, (don't dislodge the rubber O ring seal!)

What i did then, after deciding i was'nt going to fight the clamp at this point, was to pack around the filler neck with paper towel..(NOT RAG)
I then drilled carefully and slowly through both side walls of the filler neck.
I then used a powerful magnet to remove all traces of swarf from the area, being careful not to let any into the tank.
Refit the gubbins and the jobs a good'un


p.s Don't forget the rubber O ring or you'll just have to remove the bits to retro fit it
(how do i know this?? )

p.p.s - The reason for using paper,not rag! if you drill too far, too fast that drill bits gonna spin that rag quicker than you can release the trigger..possible damage to you, the parts or the paintwork...and if you're unlucky all three and possibly more.


In these days of litigation etc... If you dingle up....tough... you should have thought about it a little more
