I wouldn’t hold much stock in frame numbers relating to when they were actually used. While visiting the factory I met with the club coordinator and asked if they could date mine (chassis 1015) and got a chuckle in response. Back then, a big pile of frames would be delivered and used randomly - no “first in, first out”. It’s also partly why the early bikes vary - mine has the choke down by the carbs, other bikes I know with numbers between 250 and about 500 had it on the steering stem. I subsequently found the build ticket on the bike, very faded but early May 1993. The corresponds to date stamps on various other bits. A buddy has 502 chassis and it’s about 6 months later build
Oh that’s not the full frame number just the last three digits, mines a L plate so anywhere between 93-94. I hold no merit or value in having a lower value frame number, I don’t buy motorcycles as investment merely to enjoy.
Yep, it looks like part 17 connects via pipe 16 to the spigot next to the fuel level sensor which this one’s not connected to. This one’s had part 17, the fuel cock, bolted via an adapter into where the drain plug should be. Anyway, now I know what’s what, and thank you all for your input, I’m going to leave it as it is - it works - and seal off the spigot that has started dripping fuel, not with JBWeld but something better (yet removable).
? you said yourself, that this is a very early Monster? The fuel petrol cock is in the place that it's supposed to be! i.e. - that location was used for the fuel outlet before it was a drain plug.
Just seal one end of rubber hose and clamp it to the leaking spigot. The tank on mine is from a much later model hence the differing outlets etc.
Aha, ok, so in that case there’s no seperate drain plug ? Which brings me back to - what is that 3rd spigot for? Clearly as it’s leaking fuel it’s directly connected to the inside of the tank? Aaaargh this is doing my head in
See if you can follow it with a mirror and good torch looking through the filler cap Paul? as Mark first suggested, or blow through it/rod it through if possible to try and confirm but probably a drain line? a drain that happens to pass through the tank for ease and aesthetics reasons, but just mustn't get perforated throughout it's life, because it will end up "dribbling" fuel and not as intended.
when you manage to track down which one it is Paul, you will have to either make good the flexible, or also block it up where it emerges at the fuel filler cap. They tend to block up quite well on their own at this point but there is still a risk that you could get water in the tank if you rode in the wet. I know we often find a small amount of water at the lowest point in a tank for various reasons, but just a thought.
Well ..... I'll be dipped in doo-doo ! I kept staring at the photo and just couldn't see any screw holes anywhere . But thanks for posting back Chris ...... as the saying goes .... " Everyday is a school day ! "
...and because it's an "O" ring seal, and seals around the engagement bore periphery, it needs no downward clamping so is perfect for this attachment, just like a lot of plumbing seals on a boiler.
I had drained and removed the tank so I could fix the leaky spigot and look what came out of it. It seems someone had done what was suggested above and had slathered a machine screw with 3Bond and gummed it in there . Once it was out I could insert a fine carb cleaner brush and see how blocked it is. It’s quite blocked, the thin carb jet cleaners will go in but anything from about 1/2 the internal diameter of the spigot won’t. It could be there’s more 3Bond up there. I am convinced it was the fuel supply, it got blocked and a previous owner simply removed the drain plug and screwed the fuel cock into the drain plug hole using an adapter and some ptfe tape . Anyway, if the 3rd spigot is/was the original fuel supply outlet it’s no good now so I’ve had to blank it off with some fuel hose. At least it no longer leaks and I can reassemble the bike.
As an aside, you’ll note in the photos above the fuel level sensor cable is broken. I thought I’d remove the fuel level sensor and see if it was repairable. Errr, I guess not. Why someone would just cut it off I’ve no idea.
all the Ducati Monster build assy programmes and diagrams can't be wrong Paul, If someone had fitted a later tank to your bike then it's a possibility but I notice you haven't managed to get any shots of the tank interior to show the tube runs as they emerge into the tank/where they run to as this is the only thing that would confirm one way or the other.
I have one in my Monster tank, it’s redundant as the previous owner didn’t wire it into the Translogic dash. It’s possible like many of the fuel sensors it lied continually to the rider and when it finally broke it got cut.
