Hi Waynester, welcome from Southern California! I'm not familiar enough with the 1200 systems, but there are plenty here who know them well. I would suggest you start a new thread in the 1200 subforum of the Shop Talk & References section (https://www.classicgoldwings.com/forum/viewforum.php?f=24 and click the "New Topic" button), and give any and all information you can - has any work been done on the bike, has it been sitting long, when did the problem start... We'll get it figured out with you!

welcome to classic.... try taking gas cap off vent could be cloged and creating vucuum that stops the gas flow

Welcome aboard. Are you forgetting to turn off the choke?

Is it a fuel injected model? welcome from Oz

 

[waynester]

not injected gas cap clear choke off 10min, no spark etc ... have been working on bikes for many years but ofcorse this ones mine ...

They had a problem with the pickup coils at the crankshaft, under the timing belt covers. They would get hot and quit working - not sure if they would work after cooling down. I think someone installed a set from a 1500 with very little modification. I don't remember if it was here or on the Saunders site...

 

[detdrbuzzard]

check the fuses, old fuses can sometimes expand from heat so there is no connection. once the cool down all is well until they get heated up again

 

[joedrum]

well i wouldnt be to discourage ... seems like everything else is fine ... you will get this beat

 

[slabghost]

Check your other thread some good suggestions there.

Interesting problem. Here are some things you can do to help narrow down the problem area. Photos of pictures are in order of the way to do them. Happy hunting and let us know what readings you get. Highly unusual for both pulse generators or both coils to go out at the same time which leads me to believe that it may to loosing the coil ground up on the front of the frame. Honda switches the ground on the electronics to turn things on and off so you could also have problems with the kill switch or the starter button. I would do these checks when it refuses to start with no spark.

Might be good to merge the 2 threads.

Threads merged.

Switch gear does make sense, maybe bypass ignition/ coil circuit with a relay.
