For future memory, i would like to know which ones are, in your estimation, the "bestest", fattest, no-compromise Coils for my 1000 SP.
Ebay has these http://www.ebay.co.uk/itm/BOSCH-12-v-Super-Ignition-Coil-Moto-Guzzi-Bosch-Part-00012-BLUE-3-3-Ohms-/371724312327?hash=item568c7edf07:g:mHAAAOSwvg9XdXI9 They seem the same as in this video (from 10:27 to "I'm bitchin', not braggin' " ;) , and the chap is obviously very satisfied). I am ready to spend more for the peace of mind linked to a name like Bosch. https://youtu.be/8w1P9bgm2zs It would be good to find someone who sells these in Europe. Then I found these https://www.amazon.co.uk/Bosch-0221119027-Ignition-Coil/dp/B003NDX684/ref=sr_1_fkmr0_1?ie=UTF8&qid=1474707727&sr=8-1-fkmr0&keywords=Bosch+12v+super+ignition+coil Much cheaper, but they look "thinner" and, I assume, "weaker" and I am not even sure they are meant for motorcycle use as the seller only says "car" (not sure there is a real difference, either). On Ebay and elsewhere I found other products, like Lucas, but they do not look as "fat" as the Bosch ones on top and I understand "fatter" coils is guarantee of better cooling and better general quality. If and when I change the coils I would like to spend the money once and know I have the fattest ones around. Not that I am doing it today, but Christmas is coming... Thanks for your help! O |

Thanks to you both.
Ken, are you happy with your Lucas Gold? The specs says the output is 40,000 volt, the Bosch apparently have 50,000. Can't make a comparison because I have non-descript "Chinese" ones which seem to work well (for now) but no frame of reference. For all I know they might have 30,000 volt or less... O

The actual Voltage will be dictated by the spark plug gap, and the air density in the combustion chamber at the moment of ignition. Usually something like 20,000 Volts as a maximum is perfectly adequate. Unless you're running extreme compression ratios for some reason. Those high Voltage coils sound like they're more for competition usage.

Exactly, in practice it will make no difference to the average engine.

Thanks again to both!
What about the cooling issue: is it true that the "fatter" coils will resist heat better? My use is not extreme, but I'd still like to run a bike 12 hours in a day, or 8-10 hours without stopping (done several times already) without having to worry about heat issues.... Or I could put it in a different way: if I fork more money for the "fat" ones, what advantages do I get? Reliability? Life span? Heating? Anything else? I mean when comparing products from reputable producers, not the baddest fattest Bosch with the non-name chinese... M

Larger diiameter should mean larger surface area to radiate heat, but the difference is negligible I would think. Heat can also be sunk by conduction through the clamps as well of course.

The Bosch ones could easily also be made in China, and sold plus a price mark-up, or they could be made in India, like their plugs!

Bosch is no guarantee of quality.
When I was recommissioning my Alfa Spider I put a Bosch HT coil on - it consistently failed to give me hot starts. I replaced with a slimmer Pertronix Flamethrower - works every time. Guzziology recommends these too for Guzzis. |

Thanks to both again.
I have seen there are several types of FlameThrowers available 40,000 volts 1.5 or 3.0 Ohm 45,000 volts 0.6 Ohm 45,000 volts 0.32 Ohm Is any of those good or must I pay attention I do not buy the wrong ones? The dimensions would appear the same and I am noticing whatever works on old VW bus/ Beetle might work here? Thanks O |

I think you're worrying a bit too much. My 750 is still running on its original coils from 1975, and that includes years living in Italy with pretty fierce temperatures, commuting through London and cross continent touring. The Lucas coils already mentioned will work fine and won't break the bank.

Ah yes, I worry a lot! ;)
The idea is that whatever I buy for the bike should be top quality in order to avoid "spending twice", and if I travel with it abroad (as I hope to be able to do next year) it would give me additional peace of mind. But in this case I also have another problem: as I don't know much of electrics (I remember hearing about Mssrs Volt and Ohm at school, but I forgot what they were about) I have no idea whether the product I might be buying would work on my bike, or whether it would be the wrong one because it has the wrong Ohm (or, even, the wrong dimensions, though to me they all seem to be the same). But yeah, I am the anxious type. I will spend more for added peace of mind. O |

I'm the same.
Which is why I never got meself a Benelli. And have only bought new bikes. Spanner men would not know this anxiety. |

Very true, RLO!
I have already been left stranded six or seven times because of electric or electronic problems (almost all with a Guzzi V11 with gremlins, plus once with a Triumph Thunderbird Sport) and tend to dislike the hours-long wait for the recovery service.... particularly abroad (happened too, but with a BMW). So coming back to the topic, if I bought these Would they work on my Spada? The seller lists a lot of (car) models, and I do not know whether I am running the risk of doing something wrong here. You will notice there is a menu with the type of car you have, and it does not fit, for example, the Beetle that I thought is the usual reference, therefore I wonder. Yes, I am that ignorant in such things... M
