Strong fuel smell in the ST1100
« on: October 27, 2014, 02:14:00 PM »
Hi Guys, last Wednesday I went for my first ride since the restore of my 2000 ST1100, after parking the cycle for a short time in the sun upon return I noticed a very strong smell of fuel, a quick look about could not disclose a leak anywhere so I decided to return home, whilst riding the machine the fuel smell became more evident so I stopped to carry out a further examination nothing obvious could be located however, I did notice that the breather tube end was sitting in the rubber compartment under the tank cap and the end was exposed, question, is this the normal position for the tube ? should there be some type of fitting on the end to eliminate fume smell ? should there be a one way valve attached ?        Regards, Muf

A picture is so much easier.......the hose just sits on the fuel cap as shown.......it's a vent hose with the other end coming out beneath the bike somewhere. There should be a little spring clip on the end of the hose as well.

That's exactly what it looks like in the photo, thanks for that, I will search further to locate the other end of the tubing, I was of the opinion that the bloke I purchased the cycle off might have just screwed an unknown item to block the breather.   Regards, Muf

Check the little return fuel elbows under the carbs for splits. Especially the one over the alternator :eek

Thanks Guys, must say other than this small problem, I am very impressed with the ST1100s, great machine, still waiting for the decals to arrive from the States, been four weeks now, should look smart then, they were ordered in silver to go over the pearl burgundy two pack with five coats of clear to top it off, feel liken a rat with a gold tooth now, sold a 1983 Goldwing that I found was too heavy for me and must admit, the ST is by far a better cycle to ride         Regards, Muf

Find that fuel leak now!!!
Mine had a strong smell of fuel just before it burst into flames (see Disaster, Sadness, Tears). Did you only smell the fuel after filling the tank? Does the fuel smell come when the key (and therefore the fuel pump) is on?
Please fix this before we lose another of these great machines.

Stevo, mate couldn't locate the problem at all, went for a 130 kilometer ride today and no hint of fumes from the machine, initially the smell was both when the cycle was parked then more obvious when riding so much in fact that the fumes had entered the full face helmet and burnt the eyes {not impressed then I tell you suffered big time after I arrived home, wife thought I was on the beverage because of the red eyes and feeling half sloshed} sorry to hear the news of your machine, you must have been devastated

Hi Muf, Item 8 is the suspect hose, the fitting on vacuum shut off is larger diameter than the hose ID causing the hose to split and directly over the alternator.

So at what age does this "old enough to know better" kick in?

Thanks for the Yorkie, advise taken, might just strip all plastic fairing off and do a thorough search, I replaced all hoses I thought required attention however, no doubt I should have been more thorough lesson learnt I guess.     Regards Muf
