Engine cutting out. Now home, updates to symtoms

[radguzzi]

Well this is not great...!

I am heading Northeast toward Maine and after 2100 miles the V11 Jackal engine started missing badlyminor  first the slight hiccup was only once in whiee and it has progressed to very often.
The first thing I have done is change plugs in the off chance that was the issue... possibly the 87 octane I was forced to fill up with at a poorly timed fuel stop.

No joy, next I stopped and bought some contact cleaner to spray Ingo the TIPS, that seemed to work for a few miles with only minor hiccups but now it is back.

I am at a rest stop in Crossville, Tenn. And was hoping for Roanoke tonight but I do not know whether I should continue or not.

I.know this is not much to go on but if you have any advice on what to check I would appreciate a call.

Thanks,
Rob

I will be here for a few more minutes and then check in at tbe next fuel stop.

What is the status of your side stand cut out switch?

[Cam3512]

Bad gas?  Dump in some SeaFoam...

[pehayes]

Does the Jackal have a sensor in the right side of the bell housing?  If so, that picks up clutch swarf and gets dodgy.  Easy to remove and wipe clean.

What does your gravity fuel flow look like?  There is a huge filter for the FI system.  However, upstream of the pump is the tank's petcock and that petcock has a tiny filter about the size of a pencil.  Tank debris can clog that filter easily.  When you stop, the debris falls off.  Next time you run the bike, it seems fine for a bunch of miles until the debris gets up into fuel and again sucked onto the filter screen.  Pull the fuel hose from the petcock and turn on the key.  It should flow fuel just like any gravity petcock.  Remember, in a FI system, the pump is always circulating fuel just like the water in a fish tank.  Thus, much easier for debris to get at this little filter.

The sidestand switch is unplugged.

I thought about bad gas but I have running four tanks a day...

I need a place to tear into that fuel system in the event that something unexpected breaks, the rest area is no place for repairs.

I am heading back out and I'll check in later.

Thanks'

What about the electric fuel petcock?

If you still have one, it could be restricting fuel flow.

I know my Bassa cut out and acted strange before totally dying on me with the electric petcock gone bad.

[Kent in Upstate NY]

Does the bike seem to run out of fuel or does it just die? If it does the former it could be your petcock filter.

http://www.powersports-pro.com/ Corban Eells is good - (865) 255-2188  Maryville, TN, if you're heading east on I40.  Cut over on 321 through Lenoir City.  If you get stuck at Corbans or near, drop me a PM, I'll be around off and on.  Corban is good.  I also know places to avoid. Corban probably has time to run you through quick, but Willis in Knoxville is very good, too.  Busy busy.

I agree with the petcock as a possible suspect, also the kill switch on these can be an issue. Restriction at the petcock should change the sound of the fuel pump.

[Karl Von]

I had a similar issue on a trip awhile back while riding my centauro,  ended up being a bad coil cutting in and out.

[Dharma Bum]

You might try pulling and reattaching as many electrical components as you can reach.  I had the same symptoms on my 96 Cali.  The connections at the coils turned out to be the culprit.

[radguzzi]

The power loss is as if the bottle just falls out for a split second and then I can power through it. 

I will try checking all connections but I'll fear this may be a show stopper.   If this totally craps out at a bad time then it could be a dangerous situation.

I still want to make it to Roanoke.

If I have to catch a flight back and find a place to leave the Guzzi for pick up from a shipping company I can do it from there.

Man, this is not good .

[Kiwi_Roy]

When I bought my EV in Denver I found it would run out of power on the hills, it wouldn't actually cut out just bog down. The fuel filter was blocked, I took it off and shook it up with the fuel remaining then let it run back out the inlet this was enough to get me back to BC.

If it's cutting right out like loss of electrics remove the side cover and hot wire to the ECU relay, second from front, this will bypass all the interlocks, ignition switch, kill switch.
The first fuse from the rear of the bike is the petcock fuse, if you can get 12 Volts there the ECU should be happy
The hot for that fuse comes from the stand relay normally closed, from kill switch from ignition switch
I would remove the stand relay and poke a wire from the battery into the center small socket, if there's no connector in there it may use the 87 connector (large one in the middle)

In the case of an intermittent electrical I always suggest to monitor the petcock fuse with a small 12 V lamp. It's the last point before the power goes to the ECU relays, even if you have a manual petcock chances are Fuse 1 is still wired. If you pass a Radio Shack or automotive parts outlet get a small 12 V lamp with wires attached, jamb one wire in with the fuse the other to chassis.

Is it sensitive to the throttle position?
Sounds like a bad spot on the TPS.

[Kiwi_Roy]

I agree with the petcock as a possible suspect, also the kill switch on these can be an issue. Restriction at the petcock should change the sound of the fuel pump.

Is the pump unusually noisy?

It's easy to check the fuel flow, uncouple the return hose where it joins the tank at the front by the headstock (its the one with a connector nut) and direct it into a bottle. you should get a full pipe flow several gallons per minute.
If you just get a dribble there's the problem.
If its cutting like loss of electrics hot wire the sucker as per my previous.

Take note next time it cut's out, does the tacho return to zero while the engine is still spinning?

One other thing, my EV came with resistor type HT lead. it started to miss on one cylinder then cut out with throttle opening getting progressively worse over a couple of days, there was a gap in the core at the coil end, the temporary fix was poking a strand of wire into the core to bridge the gap.

[Greenman]

replace the micro iso relays.

[yrunvs]

is it heat related. does the bike run fine cold and then acts up when its warmed? I dont own one but does a guzzi have an ignition coil?

It has 2 coils so a failed coil will only take out one cylinder

[Groover]

Sounds electrical. Go in a dark place make sure nothing is shorting when you throttle through the rough spot (like a loose or rubbed bare spark plug wire). I also suspect a bad coil. Good luck!

Get it to the closest u-haul dealer, rent a one way van. Has to be cheaper than the above.

But do NOT tell U-Haul folks what you want to put in their truck ... or you'll be renting an empty truck to pull a trailer. 

BTDT.  [Imagine angry & tearful emoticon]

Don't use U-haul as they are the most expensive. Try Budget. Oh, and tell them you are hauling "household" goods.

First of all try and find a Guzzi shop that has the equipment to diagnose what is wrong. Misses and cutting out are hard to fix on the computer.

Good luck,

Rad,
I'm an hour ENE of Roanoke (Lynchburg) Have pup & trailer, I can come & pick you & the bike up. Have tools, a few parts & place to work on/store bike if needed. also spare bedroom.  Let me know if i can do anything to help, (434)993-3841.

And that is the best solution thus far. Way to go.

TPS is my bet.

[Rich A]

TPS is my bet.

My Jackal was dropping rpms and popping at low speeds like the whole system had a short. I replaced the TPS and that fixed the problem. I have the old TPS, which would probably get you home. I could Fed Ed it to you.

Sorry for the late post....  I have been out running the rain.

So the thing straightened out for a tank full and now it is back to the same tuff...

More later, I just got in to Waterville, no Marriott rooms in Roanoke.

Thank you all.  Back when I can type on the iPad...

Seems to reason fuel component related then, fuel filter or something that gets moved around and then gets sucked back into place and causes fuel starvation. A loose connection somewhere but to go a whole tank regular running and then when new gas is added? Filter.

Not sure where Waterville is, but if north of Roanoke you are not that far from Winchester Motosports -- http://www.winchestermotosports.com -- where a very fine Guzzi wrench (Mike) works.

Most likely the petcock filter. When mine clogged a full tank of gas relieved the symptoms. The crud had gathered around the petcock filter but gas got through the top, like a straw.
