Title: Fuel Leak
Post by: garym on June 15, 2020, 12:50:45 PM
Ok.. Lets start with a little history..

Have tidied the XS and started her up 10 days ago...…  Running lumpy as it was the first start up in 6 / 8 years... New plugs and fresh fuel approximately 4 litres in the Tank..... Oil change with filter..

Yesterday I had planned to take her for a gentle ride to move some muck..  Put another 10 litres of fuel in the tank and its probably got circa 14 litres in it now....  Started the engine and she was as before running lumpy,  only after a minute or so fuel started running out of the Air intake from the plug  / grommet type thing underneath central of the air box...

Abandoned the ride and a tinkered with some other bits before rolling her back in the lock up... Much to the disappointment of myself and my 'Wingman'   So anyone had the same ??

As a note Carbs haven't been off or engine out...…   :frustrated: :frustrated:

Could be a couple of things Gary.
There could be crap in the float bowls holding the float valve open, try draining the bowls from that screw at the bottom of the bowl. It could also just be a stuck float valve which might sort itself out just by a tapping on the side of the bowl.
It could also be that the fuel tap valve isn't shutting off and it could be allowing petrol to leak straight through. Though if the float valve isn't worn it would be able to seal.

The Float Bowls I should be able to deal with.... Should also be able to tap the Bowls as well....

Yes mate. Is yours still a standard set up? Left feeds the two left carbs and right the other two.
There's a diaphragm valve type affair in each tap.
Title: Re: Fuel Leak
Post by: garym on June 15, 2020, 03:34:52 PM
Would that have been the case when I only had 4 litres in it if it were the tap diaphragm?  Because I didn't have the problem at that time :undecided:

I don't know. Were you on reserve?
Title: Re: Fuel Leak
Post by: garym on June 15, 2020, 03:47:22 PM
Yep at that time … Once I put the extra ten litres in I moved the taps to the vertical position...
Title: Re: Fuel Leak
Post by: FJ111200 on June 15, 2020, 03:53:23 PM
So when the taps are in the OFF position does it/they still leak?
Have you tried tapping and opening the float bowl?
What else have you done to find out where the problem lies?

Post by: garym on June 15, 2020, 04:11:14 PM
No 'off'  position on the 2H9,  Reserve / On or Prime only.... Only happened late yesterday so will drain the bowls first and give them a tap...  Can the bowls be removed whilst on the Bike?
Title: Re: Fuel Leak

Title: Re: Fuel Leak
Post by: garym on June 16, 2020, 09:06:46 AM
As there is no 'OFF'  position on the 2H9 fuel taps, if I remove the Float Bowl Drain Plug,  will I need to clamp the fuel lines or would it only drain what's in the bowl ?
Title: Re: Fuel Leak
Post by: Plod on June 16, 2020, 09:29:28 AM
You should only lose what's in the float bowl and lines (the small bore hose from the tap to the inlet actuates a diaphragm in the body of the fuel tap - so no vacuum = no fuel released unless the internals are worn out) there may be just a little 'dribble' but that should be a negligible amount - hope this helps - regards Kev

Title: Re: Fuel Leak
Post by: garym on June 16, 2020, 09:54:40 AM
Cheers Kev,  So if I don't clamp the lines and the fuel does p**s out it could indication of knackered Diaphragms in the taps ??  Guessing there is a refurb kit available for petcocks?

Quick update:

Drained float bowls down all four.. Was a reasonable amount of grit / crud / alien stuff in them but nothing to terrible I guess...  :tongue:  ( I do have an image but for the life of me cant work out how to upload them or even my Avatar which appears to have disappeared )  Off side float chamber appeared to empty more then its contents as opposed to the other three... So guessing it might be the one with the sticky float.... Gave all four some shock treatment and put all the drains back in .. Reconnected battery and started the engine... Ran much better than Sunday and appeared not to have any major fuel leak as the last time started it...   However it is smoking a little from the off side exhaust and at the moment I am hoping it will clear as its only its third start in 10 days...  It didn't I add smoke at all when it went in to dry storage but hadn't been started for 7/8 years....  :rolleyes:

I had changed the oil and oil filter and applied three litres of fresh oil although the level in the side gauge is sitting above the lines, should I be draining a little to get it on or between the lines??  Could it be over filled ??  :argue:
Title: Re: Fuel Leak
Post by: Steve D on June 17, 2020, 01:57:04 PM
As an oil change with filter should take 3.7l then if you only used 3l I would check it hasn't filled itself up with petrol
Title: Re: Fuel Leak
Post by: garym on June 17, 2020, 03:32:09 PM
How might that much fuel get into the crankcase?
Title: Re: Fuel Leak

After 7/8 years of sitting valve stems have probably went hard.
Title: Re: Fuel Leak

Title: Re: Fuel Leak

Take of the exhaust and look at the valves if oil running down them seals fooked.
Title: Re: Fuel Leak
Post by: garym on June 17, 2020, 07:48:45 PM
Mate, :cry: Hoping that's not the case. Is that an engine out or can it be done while in the frame.....?
Title: Re: Fuel Leak
Post by: FJ111200 on June 17, 2020, 08:39:30 PM
First of all Gary i'd start off with the fuel leak. Then consider the smoky exhaust. It can be done with engine in frame, various methods.
But if it's not burning too much oil i'd just keep topping it up. Ex despatch rider habits die hard.
Title: Re: Fuel Leak
Post by: garym on June 17, 2020, 08:58:15 PM
Hope so as it's ever so slightly negging me out... Down the lockup in the morning and hopefully the fuel issues will be resolved and go from there.... Strangley it did smoke a little on its first start and then stopped completely and then chuffed some out yesterday.... :frustrated:
Title: Re: Fuel Leak
Post by: bradster on June 17, 2020, 09:34:31 PM
I had the fuel tap leaking ,running out the airbox an all the other symptoms.....result one smoky engine full of fuel an it ended washing the bores an burning oil like a two stroke ...

My advice on this is buy those replacement fuel taps non vacuum  type ,sort out the  carbs an save yourself a top end rebuild piston and rings etc ....best thing i have done to my old bike ...and fj1200 advice is pretty much on the money ...
Title: Re: Fuel Leak
Post by: garym on June 18, 2020, 12:32:26 PM
Had a little bit of tidying to do with the fusebox and the fired her up. Is definitely starting easier every time. :smile: Running a little rough but again appears a little better each time, or that may be wishful thinking... About a minute and a half in started to puff a little smoke out of the offside pipe but :rolleyes: nothing like Tuesday evening... Fuel leak or should I say petrol that was generally running out of the bottom of the airbox appears to have stopped... :beg: Going to let her sit all warm for around ten minutes and then restart to see if the smoke from the pipe is the same / better / worse.... :popcorn:

Hello all.....

Well fingers crossed we officially have another xs1100 back on the road..  :yipee:

Tinkered and pulled the current fuse box around so all was tight and working, in truth does need to be changed in the very near future..   :rolleyes: The fuel leak and also the oil burning again appears to have subsided.....  So at approximately two pm yesterday I put the seat back on and after warming her through earlier fired her up for a second time…  :cool: Helmet, Jacket small rucksack complete with basic tools and small 'Fire Extinguisher ' :evil:  not taking any chances after tidying this for near on 11 weeks....  Rode it for a approximately 8 miles and all good ..  :clap:  Didn't go above 55 mph and smoking does appear to have cleared, however haven't really pushed her yet so yet to be seen... Had a smile like my ears where going to fall in to my mouth on the way back.. Soooo good to have her back on the road, wound my clock back about 20 years at least....  Back to the lockup and away....  :grin:

Picked up 'Wingman' Xavi ( my nine year old ) who has on and off generally helped out with the recommission and he decided he wanted to take the plunge and 'pillion' for the first time ever.. Talked him through the basics and showed him positioning etc and also gave him an understanding of not moving around quickly on the seat and away we went...   His Words .. 'Dad that was the best day of my life !! , when we returned ..  Only did about 4 miles but he was like a dog with two d*cks....   So when is the next meet...   :cheer: :cheer:

OK, took the Old Girl for a slightly longer run today circa 40 miles... Didn't push her hard and not above 65 on the Dual carriageway.... When I stopped around halfway and parked up I have a weep / dribble of an oil / petrol mix coming out of the bottom of the air box..... Put my finger over it and definitely oil with a little petrol.... Site glass still showing oil over the max so should I drain some down and see if that cures it??

Post by: garym on June 28, 2020, 05:24:50 PM
According to the MOST history the mileage is accurate showing currently just under 14K.... Guessing I have just inherited my job for the Winter Season... If the oil were over filled would that push a little back from the breather into the air box?
Title: Re: Fuel Leak
Post by: FJ111200 on June 28, 2020, 05:30:38 PM
I think it would have to be seriously overfilled for that.
14k miles is nothing for sure but it's an age thing for the rubber o rings, diaphragms, etc.
I know Gary, it's always oh fukin no, pain in the ar$e time, but i'd like to look on the bright side for you, maybe someone else might be able to shed a bit of optimistic light  on it.
Title: Re: Fuel Leak
Post by: garym on June 28, 2020, 08:11:48 PM
Where might the oil be coming from and why as in what is forcing the oil to the bottom of the air box ? Not loads but some.... :popcorn:
Title: Re: Fuel Leak
Post by: FJ111200 on June 28, 2020, 09:15:04 PM
What should happen there is that when hot oil vapours come from the engine breather into the air box they are then supposed to go into those two top tubes and get fed into the air intakes for the carbs and then get burnt off in the combustion chamber.
Maybe there is a blockage in those two top tubes causing the oil vapour to collect en masse and form a pool at the bottom of the air box.
Title: Re: Fuel Leak
Post by: bradster on June 28, 2020, 10:38:21 PM
Been reading your posts , fj1200 advice is good advice ...it's difficult to diagnose faults without seeing hearing the bike etc..

I have a strong suspicion that your fuel taps arent closing off properly ,which is letting fuel seep past the needle valves ,which in turn is starting to fill your sump with petrol  this in turn is blowing up through the breather pipe into your airbox ...

The petrol thins the oil hence the higher oil level  ,the thinner oil will slowly destroy your rings , this causes more crankcase pressure and blows the already thin oil up the pipe.....

Sort out the taps, then service your carbs ,then fresh oil an filter ,

Be a shame to spoil a low mileage engine because of the simplest of jobs ....


Hope that doesn't sound like a lecture ,not meant to be .... :cheers:
Title: Re: Fuel Leak
Post by: garym on June 29, 2020, 08:35:26 AM
All sound pretty sensible so will be getting my hands on two sets of tap refurb kits to start.. Not looked yet but I imagine Yambits will be hearing from me.. 

I will ask this however... If the fuel is by demand 'Vacuum' does it follow that the fuel can still exit the tank even if the engine isn't running and creating the vacuum?  Noting that I only have Prime /On /and Reserve only on these taps and no Off position !! 
Title: Re: Fuel Leak
Post by: Tom on June 29, 2020, 09:49:12 AM
Surely its an easy job to test your taps to see if they shut off, before ordering repair kits?

If you have no vacuum from the engine coz its not running then the taps should be "off"

If you need a genuine "off" position in case the vacuum diaphragm and plunger are not working there is a mod that can be done to the taps to give you an off. Remove the front chrome plate and file off the tab that stops you turning the tap lever vertically upright - the "off" position.
Title: Re: Fuel Leak
Post by: garym on June 29, 2020, 09:53:21 AM
How about if I pull both the fuel lines off and let them drain into a collector of some type over a day or so I imagine that would give some indication if they are letting fuel by naturally??

By the way Tom had realised it was simply a stop that needed filing....  :rolleyes:

They did have an off, they are vacuum taps that are "off" until the engine vacuum turns them on.
Title: Re: Fuel Leak
Post by: garym on June 30, 2020, 11:13:31 AM
So Tom based upon the thread do you think it may be worth me attaching two pipes one to each fuel tap with a collector at the bottom and pop it onto the centre stand and see what happens over night?
Title: Re: Fuel Leak
Post by: Tom on June 30, 2020, 12:16:22 PM
Exactly!

Surely its an easy job to test your taps to see if they shut off, before ordering repair kits?

If you have no vacuum from the engine coz its not running then the taps should be "off"

Put your tank on a bench and see if it drips

I'm not saying anyone else is wrong, it s all good advice, only before buying stuff check whether you need it! :hitme:

I have a vac-tap that gave trouble, it clanged as each vacuum pulse pulled on it, I'm guessing the diaphragm has a pin hole. Enough petrol gets through to run perfectly but the clanging noise through the tank had me thinking the crank was destroying itself. I just run it on PRIME now, leaving the other side as reserve indication. I've also found this a good way to use the taps regardless of failures, when you go onto reserve its only on two cylinders - much safer in traffic, and as my right tap is on PRIME its the left I have to swap to reserve with my free hand leaving my throttle hand keeping the bike safely moving.
Title: Re: Fuel Leak
Post by: garym on June 30, 2020, 03:29:11 PM
Will whip the Tank off tomorrow evening..... Thanks to all for the input.....    Tom little bit confused and I read it a couple of times.. You typically ride with the right tap on prime and left on reserve?   Why not both on Prime or have I missed something and are being dim.. :hitme:
Title: Re: Fuel Leak
Post by: Tom on July 01, 2020, 09:11:08 AM
I ride with right tap on PRIME, and left to ON, that way I have a RESERVE option on the left side, which lets me know when fuel is low. If I rode with both on Prime I have no low fuel indication and theres nowt worse than running out of petrol.

Using only the left for ON and then RESERVE means I get a low fuel notice (misfire on 3 + 4 cylinders) but only have to switch left tap over, easy with throttle hand still in use.

I do try to remember to set trip to 0 when filling up, my different XS1100s have different ranges, which also change with load and headwinds.

OK shot round during lunch and de-Tanked her...

Propped the tank at the same position approximately as it would sit on the Bike and turned the taps both downwards to the 'On' position.... No leaks.. :rolleyes:  Turn them to 'Prime' and it pi**es out... Turn it all away round to 'Reserve' and no weep... However for a split second in-between 'Reserve' and going back to the downwards 'On'  position it has a little squirt on both taps, should that be happening ? .. As soon as I get it to the bottom 'On' position it stops... So for about 5 mm of travel it dribbles..  Going to leave it over night … 

Anyone have any thoughts.. :popcorn:
Title: Re: Fuel Leak
Post by: Tom on July 01, 2020, 03:51:22 PM
Thats the construction of the tap, theres little galleries that fill with petrol, when you're swing it round past the openings that bit of fuel drips out, but doesn't refill as the fill hole is blocked off in that position

OK, tank off all night and up until around 1.00pm so circa 26 hours... Not a drop in the bottles 🤔 Won't get to to ride it until possibly Sunday so will look again then.... Mmmm as the oil sight glass is showing over with oil, might it be pertinent to drain a little ??
Title: Re: Fuel Leak
Post by: garym on July 03, 2020, 11:25:31 AM
Could it be me and because the oil has been around combustions as such, am infact smelling burnt fuel and it is infact my sump being over filled hence why I asked should I drain some off.  Unless anyone else has had an experience they could consider similar?
Title: Re: Fuel Leak
Post by: FJ111200 on July 03, 2020, 04:45:36 PM
OK, i'll reply.
The rumour is that oil thinned by petrol increases the chances of the crankshaft bearings spinning out of their seats and that's not good. If it has been diluted by a small amount who knows what the volume could be to cause the spun bearings. A little amount might not do anything, who knows, would you like to find out?
If it was me and considering the price of an oil and filter change, i'd change them because the cost would outweigh the price of a fukked engine.
There you go, that's my opinion.
Title: Re: Fuel Leak
Post by: garym on July 03, 2020, 05:24:29 PM
I agree with the Oil Filter and Oil Change... However I only changed them around 3 weeks ago and was confident I put the correct amount of oil in …  :frustrated:  Think I will drain it down completely anyway and measure the amount of oil that is in the collector.... At least that would be a second thing ticked off the list ..  :tongue:
Title: Re: Fuel Leak
Post by: garym on July 06, 2020, 10:07:04 AM
Whoops, Drained the sump down and removed the oil filter which had only been on around 3 weeks max and OMG how much oil had I put in.... I measured close on 5 litres what a  :muppet:  Even my nine year old 'Wingman' asked should there be so much... No idea how I miss calculated that...  :hitme: However fresh oil and tidied her all up and out for a circa 50 mile run..  :sunny:  Small and I mean very small weep from the air box on our return, but Boy did she run different, felt much more lively and responsive... So going to put some fuel ads in for a month or so to see if it improves the general running of the engine , which in truth isn't that bad at all at the moment... Fingers crossed...

On a foot note, excuse the pun.. My Boy had his third proper ride out yesterday and when we were almost back at the lock up tapped me on the shoulder and said 'Dad don't be mad at me and pointed down.. On the nearside exhaust was the remains of the bottom of his white boot type thing which he thought had been on the peg and was in fact resting partially on the pipe... Bless true Biker was more concerned about the bike then his boots  :rofl:

I accidently checked my oil while the bike was on the sidestand one morning ( after nightshift is my excuse) and topped it up. Ambled along the highway quite happily until we headed for the hills and put some load on the motor. It started to misfire a bit going up a long climb (2 up) and looked in the mirrors to see big clouds of smoke coming from the pipes. pulled in at a servo at the top of the hill to investigate and there was oil dripping from the airbox. Sightglass was still reading full though, so after cleaning out the bottom of the airbox, I aborted our mountain cruise and limped home. Drained out about the same amount you stated and ordered a new air filter as this one was soaked. I also attributed the problem to a quite worn motor getting excessive blowby under load and pumping the oil vapour into the airbox. Just saying :frustrated:

Get that! But strangely I wasn't rideing like James Bond... :grin: Did have the misfire mind and still have a little weep at the moment after correcting the oil level etc.. My bike has 13+K miles on it and if you go by records suggests it to be reasonably accurate, unless anyone on the forum knows differently :tongue:  May be the case that where she has sat for such a long period it has had a negative effect.... :popcorn:
