1100GS refusing to play...

[Dragon Master]

Right, last weekend (01:30 Sunday) I was about two miles from home having just ridden back from Mousehole, about 440 miles, when the bike just died.
No warning, no coughing and spluttering, it was pulling up a slight gradient about fifty in fifth, and somebody flicked a switch off.

I had a fuel problem a few weeks back, but on advice from Roy at RGM I fitted a new filter, that problem cured. But even with a knackered filter it would run to some extent. But not this time.

It turns over OK, the injectors are working and it's got sparks. And it primes on turning the rear wheel. Basically it's as though Lord Voldermort has hit it with the Avardcadavera curse, it seems in totally healthy condition, it's just dead.

Any ideas out there?

I said the injectors are working. Sort of. When I checked them during the fuel problem, they had a nice aerosol spray. Now it's more of a dribbly squirt, a jet with droplets.

Oh, I did change it from Red to Black a couple of weeks before the Cornwall trip...

Cheers,

Dave.

Did you fit the filter the right way round? It sounds like symptoms you would get if the filter had collapsed inside.

Yep, it's got a bloody great arrow on it pointing the direction, and my German is good enough to understand 'AUS', even though the other writing does say 'Ducati'. (As recommended by a thread on here...)

If you take the plug caps off and turn it over, it will have a similar affect to what's going on.

Hmm.. that post above sounds a bit sarky, doesn't it? Not meant to be, I was having a go at my own ineptitude rather than the reply.

When the filter went back in June, it did a similar 'death', but once on the hard shoulder I got it started. It ran roughly and didn't like anything over 3k revs, but it got me home, about sixty miles, a few days commuting to work at 30 miles per day, then a round trip to RGM (~80 miles) before I put the new filter in.

Roy suggested then that the filter had collapsed; when I examined the old one the 'out' end plate was loose. Not enough to come off, but I imagine enough to let fuel pass, so reducing the pressure in the system.

I've done a couple of weeks' commuting followed by an 1170 mile trip to and around Cornwall and back with no problems until Saturday night. There's fuel from the injectors, so I feel it would at least try to fire if it was another filter problem. there's just nothing.

Mine did something similar to this, it was a blown fuel pump fuse. After a replacement Hall's and fuse I have had no more problems!

Check the fuel pump,sounds very similar to a problem I had on mine.Pump was priming but not holding pressure,so everything sounded good,but it didn't work.

Bloody Hell, is it a month since I looked at this thread?

Well thanks all for the advice, eventually had a look yesterday, and it turns out I hadn't fitted the filter securely on the inlet pipe, and the pressure had spat it off. Fitted it back on properly this time (I hadn't pudshed the clip past the bulge on the pump outlet) and it fired up first time.

But... now the fuel pump is screaming at me. It's quiet enough when I start up, but after travelling a mile or so, it starts screaming. And I tend to get a very slight mis-fire when I relax the throttle a little to control speed. Any ideas on this?

I'm thinking that if the pump has been working to get enough fuel past the 'loose' connection to the filter, it might have been over working and is basically getting knackered. It did run for over a thousand miles on a trip to Cornwall before spitting the filter off on the way home.

It was all nice and quiet when I got the bike last year, seems to have been slowly getting noisier since about Christmas, maybe with having to work harder to get enough fuel through the original leaking filter?

Ideas/thoughts appreciated. And where do I get one of those Audi pumps I've been reading about?

Cheers,

Dave.
