Dyna 111 Electronic Ignition for Guzzi '74-96 Big Twins.
I know it could have been posted in 'sport and tour tuning and fixing', but this is a RAVING of the higest degree, if fact I probably need councelling, read on...
The electronic ignition was a headache to get going, easy to install though.
I fitted it all up and the bike fired up first pop, ran OK for about 10mins. And got up to temperature nicely.
I was just hooking up my timing light to fine tune the timing and she bloody stopped on me and wouldnt go again.
Rechecked EVERYTHING
I had also got into the wiring whilst waiting for the ignition to arrive. Fitted an aftermarket kill and start switch, highbeam relay, tidyed up all the fuse box inputs with heat shrink over every connector, got the horn working with a new relay, and replaced the starter relay as that looked old as too, and to top it off- the new ignition.
So to say I spent at least 2 hours with a circuit tester is no exaggeration.
Recharged the battery ready to test fire again.
Couldnt find anything wrong, my work passed the double check.
Fired her up, again- started first pop.
After 5 mins this time, she bloody stopped on me and wouldnt go again.
Cant be electrical, no way.
Weird, been turning it over till the battery karked it and I can't smell any petrol!!!
Yeah, I drained most of the tank to make it lighter when I took it off, she ran outta gas!!! :brick:
Up the road to fill the tin, charge up the battery again - those car size starters in the old Guzzies suck the juice. :yeah:
Gas in the tank, juice in the battery.
Fire her up and second turn of the flywheel roars to life.
Cool!
This time the bitch ran for 15 mins, got to strobe set the right cylinder, and was just fettling up the left-
You guessed it, no go, at all :brick:
Head scratching time, cant be fuel or electrical, at least Im not checking everything again, no way.
Just have a little re read of the instructions, while I calm down.. :angry2:
Oh! this is interesting-In the instructions it says ' The Dyna 111 is designed to work with stock coils or aftermarket ones with at least 5 ohms of primary resistance'
As we all know, the lemon Mk1 coils have 3.4 ohms primary.
So I cooked the coils. :brick:
My local bike shop just happened to have a set the exact same size [ space is at a premium in that compartment] and after running my tester they came up with 5.4 ohms primary. Perfect! :2thumbsup
Fitted them up and hey presto, she roars back into life again first pop.
Quickly got to temperature, and I set the left cylinder with the strobe, lovely!
Oh, not quite, its flippin stopped again.
Plugs out, earth to motor, one blue spark, one orange.
Oh dear. Plugs stuffed. :ar15:
Check manual- wrong heat range as well.
Up the road again, 2 proper plugs.
Fitted them, and well, the story has a happy ending with me cruising off into the sunset last night, big grin, more grey hair :done:
