Guzzi Diag LH injector test

Now looking for a 1200 fuel pump.

My pump says it is part number 06107200 which says its an 1100 pump? Is this correct?

EBay will show up a plethora of pumps. Not the whole assembly as it is sold by Piaggio but just the pump. They are usually available for under £20 I think. As for the filter? Once again many aftermarket options.

With the hose make sure the replacement is a hose rated as fully submersible. Ordinary FI hose won't do the trick, at least not for long.

If the assembly as been water affected, as it looks like, I'd also suggest checking the pressure relief valve carefully as these can rust their spring out and fail.

Lastly. Make sure that both the tank vent hose and, most importantly, the gutter drain from the filler, are clear and able to flow. It looks like your tank has had a lot of water getting in to it and the commonest cause for that is a blocked gutter drain.

(Edit.)All the GRiSO fuel pump assemblies are the same but as I said you don't need the whole, stupidly expensive, thing. Just the pump, which is a generic Chinese part available on eBay.

To whit.

Pump looks really rotten. Probably safer to find a good used one. Which part number to use? my part number is 06107200A which searching says it from an 1100?

Same pump in 1100 & 1200. Guzzi part number is 887423.

Glad you found the fault

Note what Pete says about water in the tank - the drain from the gutter around the filler is very likely to block where the pipe leaves the tank at the back - if it is blocked rain water will get into the tank

Yes its blocked so currently soaking the tube with white vinegar. Tank vent is ok.

I had to 'open' mine with a 1mm then 2.5mm drill rotated by hand
Nb you don't want to drill through the pipe behind it into the tank!

Been soaking in vinegar all day How big was your blockage?
Will try a drill bit too. cheers for the tip.

Nb the connectors to the pipes are meant to unscrew from the tank - which would make cleaning easier.  Mine was just rotating and not undoing hence I attacked it with a drill

It was blocked with white salty crystals for about 20mm with 1mm drill. I think that the 2.5mm found crystals for about 25mm.

That far towards the plastic inside felt worrying - but no problems.

(I was going to blame the crystals on UK road salt - but i guess you don't get much of that in Bahrain lol)

Late to the Party (as usual).
I was just about to start a new Thread, but thought it best to just add to this one.

I had the same issue back in July, on a 2017 (registered) Norge GT.

R/H Injector puffed away nicely in the GuzziDiag Test, nothing from the L/H one, although is 'felt' exactly like the R/H one in my Hand, I could feel a 'clicking/pulsing' through the Body.
Because the Bike ran fine, I thought it was probably just a 'glitch', and so thought no more about it.


Fast Forward to a few days ago.
Was helping out a friend with his 2008 Stelvio.

It had been running fine, then one day it just wouldn't start.

It seemed to be firing on one Cylinder, when it did fire, and opening the Throttle a tiny bit helped, but it just wouldn't catch.

Tested the Injectors with GuzziDiag, and similar to the Norge I did in July, the R/H one puffed away nicely, nothing from the L/H one.
Swapped them over L-to-R, same result, nothing from the L/H one. but the R/H one puffed, when the L/H one was selected . . .
Thinking about it now after what Mark said above, the Norge was probably doing the same, but I was working alone, so only had one side at a time removed from the Inlet Fitting.

I contacted Bernd, he created GuzziDiag.

He replied . . .

I never heard of this.
But I don't know how many people ever did these tests.
At the time of implementation it was working correctly, but I cannot remember which bike it was.
I will have a look in the 5AM code to check this and ask a friend of mine with a Norge 2V to make a cross check.

Then around an hour later I got this from him . . .

Ups ...

You found a bug.
I will fix it asap.

Bernd

So there we go, soon we'll be able to test both sides via GD.

You still can if you use v0.47. I've not had the need or desire to update to v0.60.


¯\_(ツ)_/¯

V0.06 added the ABS 'Bleed' Function for the Bosch and Conti Units, or was supposed to.
Apparently the ABS Unit on mine won't 'play' . . .

I don't think I know of anyone who's used the ABS option successfully. Doesn't mean it doesn't work...might be just my shit memory.

You don't have an ATE ABS module by any chance? You wouldn't be the first Stelvio owner without a Bosch or Conti module.

OPs who end a problem string with the final problem and solution are a gift to all of us

Thank you sir
