I'm a traveler. I go out and go far with a very limited budget and am always asking myself what if.I'm wondering if there is a cheaper coil that can be used in my K100. Something like the Dyna coils I use in my Moto Guzzi. Mine are fine at the moment but I like to know these things so if I need a fix on the road I can do what I need to do. There doesn't seem to be too much info out there on this so I thought I'd ask.

I know of someone who has successfully tried coil-overs on a K1100 engine. He told me the manufacturer / type he used but I never wrote it down and now I've forgotten. Sad

Does this ring any bells?

This is the only thing I could find before I wrote the original post in this thread.It doesn't sound too promising .

The technique and parts discussed in thread link I provided seemed to have worked. Maybe I should read between the lines. Laughing Coil failure doesn't seem common though. If yours fail and you don't have spares, just think of the interesting people you'll meet trying to sort it.

Oh I meet interesting people when I get stuck for sure.Last time was in 2015 .I was heading up to the Adirondacks on my1975 Moto Guzzi 850-T when this very problem took out one cylinder,a bad coil ! This guy on an MG rode past and turned around .He said if I couldn't get it going he'd come back in a truck and help me, This was at 9AM he told me he couldn't come back until after 5PM. Gave me his phone number and told me about a lawnmower shop about 5 miles away. I limped there but they couldn't help.Called him back and waited all day.He came back with a truck we loaded the bike and then asked where my friend lived.I told him I had a friend about a hundred miles away and the guy insisted on taking me there so I could spend the night someplace safe and have help getting either the part or a rental truck. I wanted to pay him ,he refused.I finally got him to at least let me buy the fuel for the trip.The road is a wonderful place.But, I like to be prepared and be able to deal with things on my own.I did fix the bike but needed to truck it home to do it .Was back on my way the next day .

Having things like coils crap out can ruin a trip on an old bike.

For my own peace of mind when I'm a couple thousand miles from home I have a box of things that can keep the engine from running and are hard to find in remote locations. Stuff like coils, fuel pump, and hall effect sensors. They are all packed in a USPS Flat Rate Box ready for my wife or whoever has it to address it to wherever I happen to be.

Having this stuff ready to go saves me having to describe to my wife what I need, where to find it, and the marital stress those conversations can cause while it saves her having to find and pack it. Streamlines the whole process so that in most cases I can have the part I need in two or three days.

Together with a few critical spares like a clutch cable and headlight bulb that I carry with me, I can handle almost anything short of a blown engine, drive shaft or final drive failure on the road.

I've got an even better system, if I have the spare I get a mate to come and get it. If I don't have the spare he will as he has a couple of parts bikes. I often borrow bits while I am waiting for a parts order. Beside the Matiz I was wondering if you could fit three small coils that would fit under the OEM cover?
Regards Martin.

In 1983 I made a return journey on my then 850cc 1977 Moto Guzzi Le Mans Mk1 from Sydney to Perth, Western Australia. The 850's have twin coils. All went well until I was leaving Ceduna, South Australia to cross the Nullabor Plain. I was some 15 km out from Ceduna and lost ignition to the Left cylinder. limped back to Cenuda at a stately 80km/h and phoned the Western Australia Moto Guzzi dealer, Stalaski's. They listened to my problem and said, "We'll put a coil on the bus, and when you get to Perth you can pay us and tell us about your trip. Coil arrived by bus, coil fitted, Le Mans in rude 2 cylinder health, proceeded to Perth and paid Salaski's. On return journey just before Dubbo, New South Wales, the Right cylinder stopped firing. Dubbo is approx. 400 km from my then home in Sydney. I proceeded home to Sydney on 1 cylinder - 80 km/h on the flat and down to 60 km/h crossing the Blue Mountains. After returning to Sydney a new coil restored the Right cylinder. Speaking of Dyna coils, a Dyna III electronic ignition was many of the improvements I made with that bike... I bit like having a Brick - great machine when made, but always room for improvement...

I have my 75 Moto Guzzi 850-T fitted with the Dyna electronic ign and the Dyna coils.I did have one of those coils fail after around 30,000 miles so now I carry spares . I've had everything fail at one point or another on just about every motorcycle I have ever owned .This is why I want to know what I can use as a spare for the K100. I always carry some spare parts when I go off wandering, I usually make it home under the bikes own power no matter how far I wander.

The 2 coils that failed were originals before I fitted the Dyna III ignition/coil system. As you say any coil can fail, including Dyna III's.

Because of the available room in the trunk of the sidecar, I always carry spare parts. But at home, everything is neatly (Or it was) pack and mark in plastic bags. If on the solo K, I break down far away from home, I can call my wife and ask her to send a specific part by courier. She doesn't know anything about bikes but she can read (Please NO comments about this statement as she may read my post. Twisted Evil ).

That's a clever way to replenish beer supplies when travelling.
