Hello folks, I acquired 2007 Breva 1100 some time ago that i can't start the bike. Hoping to find out what is the issue before taking her to the nearest MG dealer in Brooklyn, NY, which is 3 hr drive away...
So here it goes: The bike has only 1000 miles on it and looks new (I am not the original owner, bought off insurance auction, so no prior history is known). Initially, I couldn't get the starter turning. I ran the current straight from the battery and the starter turns fine, crankshaft is turning fine, but no ignition. The fuel pump primes fine when ignition is on. No malfunction light on the dash, the instruments come up fine. Spark plugs are there, all fuses are intact and spark plug wires appear intact. I though the side stand switch might be faulty, but in neutral, clutch lever squeezed - still nothing. I was advised this might be a Hall sensor issue (as a former BMW R1150 owner I know faulty Hall sensor can cause exact the same symptoms). I was wondering what do you think it can be, other that Hall sensor. How would you test Hall sensor. There must be no voltage at injector when cranking? Thank you for all inputs!

Can you hear the starter relay clicking when you press the start button? The starter relay is under the seat, and it's the only one that has a yellow wire attached. If it's clicking but the starter solenoid is not reacting, then it's probably bad battery, or poor connections on the battery or the ground strap (under the starter cover).
Watch the voltmeter on the dash, or better still connect an external one across the battery while you attempt the start. If the battery voltage doesn't drop to a low reading, then connect a wire to the positive on the battery, and then when the starting is attempted, brush the other end of the wire on the back of fuse B.
If this gets a reaction, then you have the classic "startus interruptus" symptons. Do a search for "Modern No Crank Starting" on the GuzziTech website for the solution.

Dave,
I had the startus inperruptus issue (starter solenoid clicking, not turning) and did startus interruptus fix exactly as you describe. That cured the starter issue. Now the starter is turning strong and turning the engine, but I can't get an ignition. I am thinking it is a separate issue from startus interruptus.

Clogged petcock, junk in fuel lines/filter? Spark?

The standard fuel filters are known to fail.

Look in the tank for swirling fuel when first turning on and the fuel pump priming, if so hose or filter open. Also look at the plugs after cranking to see if wet or dry, dry means no gas. Mine had the filter come apart and the bike died immediately.

Where are you - there may be recommendations for closer Guzzi shops.

Thanks guys! I am near Atlantic City, NJ

Bit of a long shot, but Tip over sensor? I've had the experience of trying to get the bike to start for 10 minutes after it tipped over with no results. I don't have the starter system bypassed so it just didn't do anything whatsoever when I pushed the button I finally just grabbed the bike and gave it a series of hard up and down pushes and it started. The tip over sensors are very crude affairs on the Breva IIRC.

Spare Parts in Philly or Sun Cycle in Manasquan NJ. I don't have personal experience with either but have read some positive things about them both on WG. When I lived down the shore, I would not have wanted to go to Brooklyn for anything routine due to traffic and roads. You'll find huge knowledge on WG so you're in good hands. Nic

If you decide you need help, I don't think Spare Parts works on something as new as a CARC bike.
Never heard of Sun Cycles.
They can be arrogant as hell, but FBF would be able to fix it for sure.
Maybe close to same distance as Brooklyn but Coopersburg Eurosports could handle it too.

Finally got back to my Breva this morning. I removed outer spark plugs, which were covered in black soot, not grey-sh as they should be. I installed some new Bosch plugs that I had in my garage and voila - the engine fired up :D It ran very rough with different sound with clutch lever squeezed. I took the bike for short spin and it did feel underpowered and was shaking excessively and the exhaust was sneezing. Reminded my old VW Jetta that was running on 3 cylinders most of the time. I ordered correct NGK on Amazon (nowhere to be found in local autoparts stores). At this point at least I know fuel delivery is probably OK. I wonder if this could be due to wrong outer plugs, or inner plugs might need to be replaced as well? I wonder what could have happened to a bike with just over 1000 miles on it for plugs to be in such a shape.
-
I think once you have all four correct plugs installed and fresh gas you are going to have a sweet runner ! Did it sit since 07 with fuel in it??
Next stop:
all metal fuel filter, correct submersible fuel lines, and oetiker clamps

2007 with only 1000 miles on, do you think the previous owner may have got frustrated and given up?
Running rough could be an electrical problem.

If it continues to miss-behave with new plugs monitor the output of the ECU relays (29) Red/Black wire then relay (30) pin 3 with a small lamp.
I'm just thinking the ECU may be dropping out because of an upstream fault/loose connection.
Wrap a small wire around the relay pin. Have the lamp at the bars where you can safely keep an eye on it.
If there's any sign of a flicker in the lamp while the bike is missing you have an important clue.

Put in correct plugs, as much fresh gas as possible, check valves, and run her for several miles. Might need some waking up.
-
Installed correct plugs and put fresh gas. She seems to warming up to me! does not feel underpowered any more. There are few issues that worry me, though. I took little cell phone video of the bike and posted on youtube here:

Let me know what you think.
1. There is noise from valve train that appears very similar to an engine with worn camshaft lobes. Perhaps you can hear it. More pronounced on cold engine.
2. There is a noise from transmission when clutch-in, as if the throw out bearing was bad.
3. I went through settings on the instrument cluster. When selecting "gearshift selector" (I suppose in this mode it shows which gear the bike is in), the tachometer hand jumps up to approx 8500 and 8400 is displayed on the LCD screen. Also, LCD appears fading out on lower left corner. Not a good sign...
So this is so far. I rode the bike more today and it is quite a different animal from my BMW r1200 sport tourer. Lots of character, surprisingly tall geared and feels very light. With the the same lean angle as with BMW, center stand (or something else) would touch the asphalt, though

Sorry bout that
That is all I get after clicking on your link mate
The Guzzi dry clutches make different sounds according to whether or not the lever is pulled to the bar. In that position they are rattley ;D

Sorry, should be public now

Can you elaborate on what you did there, did you bypass something?

Sounded fine to me, both the engine noise and the dry clutch. I haven't owned a Breva and its been about 6 years since I had a V11.
But nothing stood out to me.

Dry multi-plate clutch rattle sounds perfectly mormal

Sounds a lot like my 1200 Sport, with similar engine .... just a few more cc's. I was concerned over similar noises when I first bought the bike in 2010. I think I can find the video I took on YouTube. If so I'll send you the link.
Bob
EDIT: Here's the link I posted to this forum in 2010. I think you'll find my 1200 Sport and your Breva 1100 sound quite similar. I'm at 54000 miles, and she still makes lots of mechanical noises!

I've never ridden a Breva 1100, but there is no 'what gear am I in?' display on these bikes. I think what you were seeing is where (at least on my Sport) you can set the point where the 'redline' light begins flashing.
