looking for a more elegant solution.......

[AussiXS11G]

thats the stuff.....Threebond "Super Engine Conditioner"

and ....
the initial problem was that the #4 side of the tank goes to reserve before the #1 side - I dont use a centre stand, the tank is, well, less than a perfect shape at the mounts (having been crashed several times) - all this conspires to have less fuel in the #4 side of the tank as the level goes down.....
solution......join the taps under the tank - presto problen solved....thanks very much.

With regard to fuel running up hill... the configuration of the filters being low hasn't changed for some 10k's of km so I am not concerned about that.

the "yanks" use something called sea foam,, can't find any one who stocks it here,, I use carby clean on the bench , but wouldn't spray into carbs with motor running, haven't tried but would imagine you'd get a peak rev pretty quick, and won't clean what you want either

Whats the foam thats sprayed imto chambers to clean them where can you get it Regards Coops

Yep, she wins. -5? You can keep that to yourself. But how about a 12 hour boat ride accross Bass strait & 10 - 15mtr swells before the four days of rain? does that give any kudos? Man those first few days were cold. Guess I should have known better than to take just a summer jacket, draggin jeans & only 1 pair of summer gloves to Tassie in Feb, their warmest time of year......

i finally took some pics, here's the link http://s1106.photobucket.com/albums/h378/XS1100Aus/Bluedayts%20RH/

Hope I done it right so you can see the photos. It's a bit rough & yeah, I like cable ties (being a sparky I have an endless supply & just can't help myself). I'm going to do some more resto work on the bike this winter so will sex it up then.
As you'll see i've also connected up the Primary as well. I did this because I thought the rear outlet was the reserve outlet until Melbxs kindly told me it wasn't. When I get some spare time to tinker I'll blank them both off and put a link pipe between the two Tee pieces. The way I have it now needs both fuel taps to be working, with a link pipe it won't matter if one tap craps itself.


Cheers

mrs steptoe said 4 degrees  ,is cold ?? also said get a grip   
has personally been -5 with wind chill,  bawling telling me to stop 

we did eventually,,  was not a popular boy

will wait for the pic

Hey Steptoe, Tassie gave us all her glory this year. From gale force winds and unrelenting rain so wet that words fail me to picture perfect warm sunny days were had and enjoyed (along with plenty beer & fantastic food). As one mate pulled up at Derwent Bridge for lunch on our way from Strahan to Hobart she told me it was 4 degrees and there was snow on the mountains in the distance. Never before have I been that cold.....The last four days though were fan-fuggin-tastic (even gave a bloke on a sportsbike (06 Fireblade) a lesson as I went round him in the twistys on the last day.... ).

Fuel lines? I've cable tied the "T"s to the frame rails under the tank, run lines from there to each petckock then down to the carb inlets. I'll take a photo and post it soon, maybe tonight. And yes, all fule lines are kept well above the Carb inlets, so are well and truly above the bowls.

[steptoe]

ay john,,
2000k in 7 days, in tassie,, that's some time spent on a bike,,hope the wind and rain was good to you,

so with your fuel plumbing,, your saying even your filling "t"'s are pointing up yes??

and no fuel line is below the top of the carb bowl

[bluedayt]

hey guys,

seems like there's a lot of over engineering being discussed here. I have an RH, just returned from a 2000km 7 day road trip in Tasmania and my fuel lines are set up like this: LH petcock feeds Carb 3 & 4, RH petcock feeds Carb 1 & 2. that's it. I do not have a link pipe between them and have thrown the Vac lines to the shizenhaus ages ago. Since getting the old girl on the road in October last year I've done nearly 5000km and never had an issue with fuel. When I run onto reserve (around 200km depending on how heavy the right wrist gets) there's about 2.5ltrs left in the tank (RH's have the small 15Ltr tank remember). It's a very basic set up and when I work out how to post photos I'll post it. There's even enough length on the lines for me to lift the tank high enough to not have to remove it when balancing the carbs.

I'm not sure who's photo it is of the fuel lines but running them below the carby bowls will give you dramas with air pockets and cause fuel starvation issues. Always keep the fuel lines above the carb inlets and gravity will keep everything in check.

Just to clarify....Bryans is a Standard ...albeit with aftermarket fuel taps.I assume he s running the standard original carbys as well.
Anyways.....let s not get bogged down with dibs and dobs..........all responses are there to help fellow xs ers with a prob.......one way or the other.I have often read topics that stray a little from the original title....and found something in there thats worth while either as something i didn t know or is a different way at solving/lookingor testing a problem.
Back on topic of fuel stavation....would the addition of extra fuel line as well as the larger surface area of the fuel filters all sitting in what i would see as a fairly dead air space and copping the full heat from the cylinder heads and possibly having one of the fuel filters comming in contact with the cylinder fin be such a good set up?Just a thought for what it s worth.I would hope that they are made of teflon or other and not just a fuel resistant plastic.

[makzy]

Yeah Steptoe, rh's and specials have a different tap and line setup than std's, I still think that linking the lines would be a good idea, wouldn't hurt anyway, but i think Bryan's problem is because not using std taps with diaphrams he's not getting enough fuel pressure to the needle and seat when the tank is getting low. i'v struck this sort of problem before with engines that originally used diaphram type taps running from different tanks or taps than std cos they need more fuel pressure
     Mines doin a bit of that at the moment on the left 2 carbs cos my diaphrams are old and dry and stiff, ( bit like me) anyway we'll see how he goes hey, will give you a call about gettin to your place on the weekend if thats ok,  Cheers

differ away Jeff 

bryans and mine are a lot different from yours,, which I have never had the opportunity to look closely at,, now with makzy close by I'll get that chance

[excess.11]

Beg to differ Steptoe...the original post was to do with the problem of fuel starvation on carbys 3 & 4 and looking for a (less messy) or elegant  solution.My 1100E Standard has the original fuel tap set up with no link between the taps.as per original manufacture......and i have no probs .My point is the problem lies elsewhere and the fuel lines should nt need to be linked at all......Find the problem....and then there isn t a need to add extra fuel lines and joiners.Melbxs..........the fuel taps on the standard model have the vac diaphram cut off in the taps.

[melbxs]

The vaccuum cutoff is built into the valve unit in the octopus anyway rather than into the taps themselves. Certain of this.

[steptoe]

come on fella's,, , go back down the posts,,

lucrezia doesn't have standard taps any more, ,, ergo no diaphrams,,

the prob was the unlinked fuel lines, hence the long ugly fuel line mess    and the initial post
