Ignition control module

Postby Kama » Fri Jul 06, 2012 12:25 am



I've been reading up on the 3 yellow wire issue (which i randomely stumbled across) and it sparked a memory of something I noticed with my GL1100. When I was working on the carbs I noticed what looked like some of the ignition control module's insulation material had melted off the unit and dripped down onto the frame and radiator hose below. Is this normal something that normally happens? This bike was taken all across the US by my Grandfather so I know its been in 120+ degree weather.

On another note, I'm doing a brought back to life and stripped this gl1100s naked. Is ther a list anywhere of all the known design flaws that I need to know about for this model? He put over 50k miles on it and never had an issue an now during my restoration I'm trying to catch any known problems before they bite me. As usual all help is appreciated and I love all the knowledge I'm able to gain here. This was a bike my grandfather spent a lot of his life riding and it's put a gleam in his eyes seeing it on the road again (and me as well for being able to share it with him) and to have his grandson appreciate it. I'd love to keep it that way for years to come as well.

Found the exact same thing on mine. It looks as if the dielectric insulation overheated and melted out. and I think my haynes manual called them "sparking units"? I have not changed them out yet, but it is on the list.. :D

I wasn't sure what it was, I had to look it up on the parts lookup to find out what it was. It hasn't hurt the function or performance so I was thinking about filling it in with JB weld and calling it good.

Mine did that too.Just gently scrape the loose stuff out and fill the gap with your favorite sealer.I used black silicone.
Known issues......Here's a list
Replace the timing belts!!!
Check the water pump bearings
Put in a new thermostat.
Tighten the steering head nut properly
Flush ALL the old brake fluid out,replace with dot4
Clean or solder every electrical connection that attaches to the stator and regulator..Soldering is preferred.
Check the fork seals for leaking,and at least replace the fluid.
Pay close attention to the carbs.They must be clean and synced really good.

When it's right,the 1100 can near separate your arms from your shoulders....

Turn OFF the gas at the end of the day..There is always a chance of a weeping carb one day and it will hydrolock the engine.

A few questions about the list. On the timing belts, are there high quality alternatives to OEM? I pulled my thermostat and it was functioning correctly at the appropriate temps, should it still be replaced? You said DOT4 not DOT3, why? Everything else has already been done (except the yellow wire solder).

Dot 4 is preferred on the bike.it has a higher temp value and doesn't absorb moisture as much as dot 3. You can use dot 5 also.
I use Gates belts from Napa.
As long as the thermostat is good, leave it be.Some "mechanics" have a notion to just remove them
Monitor the voltage at the battery contacts.Walmart has a digital one that's $16 I've used on all my bikes.I watch for voltages while running to stay between 13.2 and 14.5 volts.If they climb too high or drop real low,I know there is impending problems I'll have to deal with.

Ok, I was just curious since it says use dot3 only. You wouldn't happen to have a part number on the belts would ya? We have a napa here and that beats ordering any day lol. With mine being a naked GL, I'll have to come up with a creative way to incorporate a voltage meter.

Under "search" look up reference part numbers.
The digital meter is 3/4" thick 3"x4" and is surface mount.red LED type.

It's a common failure that happens with age - just scrape as much of the goop out as you can, fill them up with epoxy, and call it good for another 20-30 years.
