PostSubject: GRiSO 1200 injector replacement??   Tue Aug 02, 2016 7:31 am

Hi guys,
Help needed ....broken injector where the conector mounts to the body need a replacement Sad
Anybody know if this is a standard car part or generic to other models of bike so can be obtained cheaply or is it a Guzzi only part?
cheers

What year? There were 2 different ones on the 8V. In US PN # 976555 is around $250 and PN #CM074706 is around $86. To cross it over you need the stamped number on the inj then search it as a Weber Marelli part.

Thanks Steve, it's a 2011 just pulled the injector it's an IWP190 Weber I think.

Have just done same i.e snapped off connector at injector body. Grr. Large difference in price with earlier one ( mine of course) really expensive. Mine is an IWP 189. Anyone know technical differences and why the change from one 8v to another and whether the later model will fit / be compatible with 2010 ? - I can find spec sheet for 189 but not 190.

Just checked info on the 189

[You must be registered and logged in to see this link.]

Here in US the Dodge dealers are an importer, good luck doing that but haven't tried it yet.

I believe the mount hole is the same for both, checking the difference if I can find it. I would use the later & cheaper one

After some more search it appears to be a VRod Harley part, read here---

The 189 is also used on some ducatis, might get one used from a breaker.

look here:

If you use the cheaper type then change left and right. You would think that a map change should be done too, if you are sensitive.

The why will be mistery forever, for cost or spray pattern?

this is the newer iwp 190:

Thanks Steve / Paul. -

Have crosschecked that info and (adjusting for units quoted by thr Harley guy) can't see any differences in spec.
Paul : not quite clear on the reason for suggestion to swap left and right ?
Beetle: do you map differently for the different GRiSO 8v injectors, or notice any differences ?  I'm assuming as I have closed loop back on it will probably try and compensate OK even if a little different. I'll rebalance and reset learning p's in any case.  

As aside I pulled plugs to check while I was there cleaning thtottle bodies etc chasing the high idle.Bit rich so i might recalibrate closed loop for slightly higher afr, maybe 12.5-13.2.   Nothing gappens until injector arrives. Did I say Grrr?

The snap event happened trying to release fuel line pressure so I could get tank off. No luck with a few starts with pump disconnected.  Tried guzzidiag firing of injectors for a number of cycles and still stuck. Went back to my normal method of popping injector off its hose but just got hamfisted. At least the quick release on tank popped of easily..

what I meant, is when you swap the broken one for a cheap newer one, then the other side should get the same, always use same injector left and right.

No. It's nothing to be concerned about unless the spray pattern is radically different.

Aha - tks Paul - yes thats certainly the plan - two matching bright shiney new ones.
Tks Mark. Both are 12 hole cones at least and seem to have identical flow specs.

If you have the two different models, connect then and use the injector test in guzzidiag to let them spay, you should easy see the pattern. Getting a picture of each pattern for us is more difficult I think. Or a youtube video made with your phone.

I had tried that before Paul when trying to check if I had blockages and have some slomo video. If I work out how to post I'll put that up. Here's a still frame from it.

I've probably got a spare rolling about in the toolbox if you're interested? I'l have a look this morning if you like?

Paul - yes thats the 189.
Pete - thanks - Mario is chasing the new pair for me - price for the cheaper ones is pretty good. If I get stuck with lead time though I'll request a toolbox dive...,

190's arrived and fitted. Not quite sure what differences are internally but externals are obvious - 190 has 6 larger holes instead of the 189 12 fine holes. Maybe thats what drives $200 per injector ??

In bike so far ok though maybe a bit rich. ( high idle still unresolved despite tb clean - 2300 rpm constant now, painful)

Have rebalanced. No change to idle problem. Reloaded Beetle's standard Ago map with Lambda off.rebalanced and idle behaviour back to normal though coughs and splutters a bit. Will see how she goes on longer run tomorrow. Smiley faces for now.

Yuck. I don't like the look of those 190's. Hole & spray pattern could well be different enough to require remapping. Poo.

Hi Mark, don't know which injectors you have in your bike, but since there are two types in the 8v engine, why not do a test logging with both types to see what difference there is. It must be notable.
Could bring another finetuning in mapping.

in parts manual, Guzzi lists,
189 for ZGULSE - ZGULSJ - ZGULSU
190 for ZGULSG

The stelvio only has 189 in the first series from 2008, the ones without ABS
The norge 8v has 190
1200 sport 8v has 189

Egads.

Change injectors and log all the different maps again, for both flatties and rollers. Then have every person I've sent a map to tell me whether they have 189 or 190 injectors. Nightmare.

No thanks.

Great run this morning. Very sharp, no stumbles at old 3krpm point. Maybe injectors were part of original problem somehow. No high idle. Really good. Went to start for journey home but no go. Cranks but won't fire and now service lndicator up. Dash flicks on/off while cranking. Ho hum. Fuses all ok but will need to hookup GD in morning, check connections etc
