I'm experiencing a similar problem with my bike. Difficulty is I have an M-Unit fitted which makes it hard to diagnose the problem. It may turn over a couple of times then click, click, click in quick succession. It seems to happen totally randomly as well.
I have a new Valeo starter motor fitted. From what I can remember when the problem occurs I've tried jumping it (making a connection on the solenoid) and sometimes it'll start but sometimes it still has the same problem. it turns over a couple times then click, click, click. The last time I got stuck I connected it to a battery charger and it started immediately (while connected) and I rode happily for hours. Went to take her out the other day and a slow turn over then click, click, click. I gave up immediately. This has always indicated a weak battery right? But I swapped batteries with another Guzzi a few years ago and that battery now works fine in that machine and now my current battery is doing the same thing (after working fine for a year or so). It makes no sense at all. Do you think getting a new solenoid will solve this?

'click, click, click in quick succession' usually means knackered battery, it's not holding a charge. When the solenoid activates, the Voltage drops too low to hold it so it drops out, this allows the Voltage to recover, solenoid activates again, Voltage drops, solenoid drops out, and so on ad infinitum. |

Yes, I’ve had that on a BMW oilhead with Valeo starter motor. The solenoid contacts eventually weld themselves together if not addressed.

Yes, that machine-gunning is usually the battery, exactly as Mike explained. Or you have some poor connection which causes the same result. That connection would have to be close to the battery, or the battery/frame connection. It would have to affect the 12v through the solenoid coils. You said that changing the battery cured the "fault" for a year or so. No doubt this replacement isn't as good now as it was then.

Makes sense. I've bought a new smart charger to see if I can repair the current battery. If the problem continues and it is indeed the battery and not a bad connection (which I've checked many times), do you have any recommendation that's bullet proof?
All of these batteries have eventually had the same problem over the past few years: Odyssey AGM 18Ah Excide AGM 30Ah Excide wet 30Ah It's worth noting that the 2nd battery I had is now in another Guzzi and works fine. That part makes no sense to me

There are Smart chargers available on e-bay £13-£17 they work on all batteries and will recover AGM batteries, mine did when the AGM battery showed under 9v .... a campervan had left interior lights on.
It took over 10 hrs to get it over 12V ..... These chargers pulse a battery and show the actual Battery Voltage / The %age charge of Battery / The charge rate in Amps then Volts. Connect to a battery with no 240V input and it will display battery Voltage and %age charge. I was undecided BUT after it recovered a very sorry AGM battery I was convinced. I use it to check my caravan leisure battery and to check the state of my spare leisure battery. I have the spare battery hooked up via a timer switch so it comes on overnight and keeps the battery healthy. Charging when needed, popping a load to create a discharge and pulsing to stop plates sulphating. At one time a bike battery would last 7+ yrs but I have experienced modern batteries giving up in 2 yrs, in fact I had one that died in 26 months BUT had a 36 month Guarantee, The company I got it from did honour that too so I got a new battery for the cost of return postage. Few people keep battery receipts, I always write the date fitted on a battery and where I got it keep them in with the log book

If your old battery is still working on another Guzzi, maybe your bike is not charging properly. Or does it have a parasytic drain on the battery when left? There is no doubt that allowing a battery to deeply discharge kills them very quickly, so if you do have a parasytic drain, better to disconnect the battery when leaving the bike for any time. Obviously it also pays to have a battery with the highest possible capacity in AH.

This is right. It’s one of the battery going flat due to a drain, or not charging, or a bad connection somewhere, if the battery has recovered enough to work fine in a different bike. |

Remember an electric clock is enough to discharge a small bike battery in a matter of weeks.

Saying this whilst touching wood so I am.
In the 90s my local car sparky did the mod to my bike. Sometimes it still just clicks. Time to change relay or clean contacts. Remember a wee dash of contact cleaner in the start button What I noticed recently was that the power wire into the fuse box was loose. Added a new connector and so far ( still touching wood ) it has been more reliable. Still keep the 4" nail in my rear footrest though. Cheers Min

One other thing rare but has happened the earth strap on the battery box fixed BUT the tag had cracked causing intermittent failure top tip fix earth to gearbox bolt
Also at one time the braided link from the solenoid to actual starter had a crack in it, these are rare BUT take time to actually find worth looking closely |

Last year I had a starting problem on my BMW airhead which has similar electrics to Guzzis of that era - after fitting a new starter the problem turned out to simply be a bad electrical contact at the earth strap on the gearbox. The bolt was tight but there was resistance between the cable eye and and the gearbox…..
The earth and power cables that carry the high currents to the starter can also break down with time and modern low resistance alternative cable sets are available, at least for BMWs.
